Energy consumption level shows a never-ending increase since the industrial era. Towards sustainability objectives, it is of outstanding importance to reduce the amount of wasted energy, that typically comes as waste heat, as a consequence of non-unitary efficiency of any thermodynamic process. Here a breakthrough in conversion of low enthalpy heat into electricity is presented, based on a liquid state device that operates through multiphysics effects: thermomagnetic advection, triboelectricity, pyroelectricity and Ludwig-Sorét effect. A synergistic interaction between ferroelectric surfaces and a complex composition colloidal suspension is evidenced, owing to an enhancement of the generated potential of 365 % in comparison to pyroelectric effect and 267 % in comparison to triboelectric effect, while the the current extracted is 54 % higher than the pyroelectric effect only and the power extracted by induction remains substantially unperturbed. The impact of this technology on society is also analyzed, on the basis of a set of practical applications, by means of a computational analysis.

Fungi cells can sense extracellular signals via reception, transduction, and response mechanisms, allowing them to communicate with their host and adapt to their environment. They feature effective regulatory protein expressions that enhance and regulate their response and adaptation to various triggers such as stress, hormones, physical stimuli such as light, and host factors. In our recent studies, we have shown that Pleurotus oyster fungi generate electrical potential impulses in the form of spike events in response to their exposure to environmental, mechanical, and chemical triggers, suggesting that the nature of stimuli may be deduced from the fungal electrical responses. In this study, we explored the communication protocols of fungi as reporters of human chemical secretions such as hormones, addressing whether fungi can sense human signals. We exposed Pleurotus oyster fungi to hydrocortisone, which was directly applied to the surface of a fungal-colonized hemp shavings substrate, and recorded the electrical activity of the fungi. Hydrocortisone is a medicinal hormone replacement that is similar to the natural stress hormone cortisol. Changes in cortisol levels released by the body indicate the presence of disease and can have a detrimental effect on physiological process regulation. The response of fungi to hydrocortisone was also explored further using X-rays to reveal changes in the fungi tissue, where receiving hydrocortisone by the substrate can inhibit the flow of calcium and, as a result, reduce its physiological changes. This research could open the way for future studies on adaptive fungal wearables capable of detecting human physiological states and biosensors built of living fungi.

The bacterial skin studied here is a several centimeter-wide colony of Acetobacter aceti living on a cellulose-based hydrogel. We demonstrate that the colony exhibits trains of spikes of extracellular electrical potential, with amplitudes of the spikes varying from 1 to 17 mV. The bacterial pad responds to mechanical stimulation with distinctive changes in its electrical activity. While studying the passive electrical properties of the bacterial pad, we found that the pad provides an open-circuit voltage drop (between 7 and 25 mV) and a small short-circuit current (1.5–4 nA). We also observed by pulsed tomography and spatially resolved impedance spectroscopy that the conduction occurs along preferential paths, with the peculiar side-effect of having a higher resistance between closer electrodes. We speculate that the Acetobacter biofilms could be utilized in the development of living skin for soft robots: such skin will act as an electrochemical battery and a reactive tactile sensor. It could even be used for wearable devices.

Designing antennas suitable for generating highly directive electromagnetic signals has become a fundamental task. This is particularly relevant for the development of efficient and sustainable point-to-point communication channels, and for energy transfer. Indeed, these are nowadays expanding areas of research. In order to deal with said particular wave phenomena, an extension of the electrodynamics equations is taken into account, where exact solitonic type solutions are admitted. These waves may have compact support and travel along a straight line, without dissipation, at the speed of light. The result suggests the design of biconic type antennas having specific properties that are numerically examined in this paper. The cones, supplied with an oscillating source, are embedded in a dielectric material of suitable shape, with the purpose of driving the signal in the proper direction. The computations based on the extended model are aimed toward simulating the possibility of generating peculiar wave behaviors, in view of practical implementations in the framework of point-to-point communications or wireless power transmission.

Technological development in robotics, computing architectures and devices, and information storage systems, in one single word: cybernetic systems, has progressed according to a jeopardized connection scheme, difficult if not impossible to track and picture in all its streams. Aim of this progress report is to critically introduce the most relevant limits and present a promising paradigm that might bring new momentum, offering features that naturally and elegantly overcome current challenges and introduce several other advantages: liquid cybernetic systems. The topic describing the four orders of cybernetic systems identified so far is introduced, evidencing the features of the fourth order that includes liquid systems. Then, current limitations to the development of conventional, von Neumann‐based cybernetic systems are briefly discussed: device integration, thermal design, data throughput, and energy consumption. In the following sections, liquid‐state machines are introduced, providing a computational paradigm (free from in materio considerations) that goes into the direction of solving such issues. Two original in materio implementation schemes are proposed: the COlloIdal demonsTratOR (COgITOR) autonomous robot, and a soft holonomic processor that is also proposed to realize an autolographic system.

Energy consumption, environmental impact and sustainability fastly rose through the rank, achieving the first places in driving investments, policies and concerns of all Countries at any developmental stage. Energy transformation, though, must cope with non‐unitary efficiency of devices and processes, which results in a distributed production of waste heat. A reduction of emissions, implying a conversion of waste heat to more noble forms of energy and a concurrent increase of efficiency of the same devices and processes, is of paramount importance. In view of the enthalpy content and distribution of the different sources of waste heat, low grade/low enthalpy sources below 200°C are considered the most fertile field for research and development, with an impressive industrial growth rate. Thermodynamic cycles and thermal conversion devices based on the most relevant physical effects are here introduced and briefly described, including both solutions that already achieved industrial maturity, and less developed systems and devices whose study is still in progress. A specific focus on three application domains, selected in reason of their economic relevance, is done: industrial processes for the vast energy and capital availability, automotive sector for its permeation, and wearable devices for the market size. Limits and opportunities are critically discussed. This article is protected by copyright. All rights reserved.

Energy harvesting from extremely low enthalpy sources can play an important role in increasing the sustainability of future energy applications: low temperature differences are common and offer an abundant source, available both in the natural environment and as the result of a many industrial process. This paper presents the first closed-loop thermomagnetic hydrodynamic energy harvester, based on thermomagnetic advection and exploiting a commercial ferrofluid. The lab-scale prototype has a toroidal geometry adopted from the well-known tokamak inertial machines. Peltier modules are used to control the thermal gradient that is harvested and converted directly to electric energy, while permanent magnets trigger the advection. Temperature sensors are installed along the toroidal walls (thermistors) and are placed in contact with the rotating fluid (thermocouples). To extract and ensure the electrical energy output, the structure is wrapped-up with induction coils. Two coil configurations (purely poloidal and mixed poloidal/toroidal windings) are tested, in a heterogeneous two-phase flow from the combination of water carrier and ferrofluid packets, reaching a maximum extracted electrical power per unit of temperature difference of 10.4 μW/K. This positions the device close to 20% of the ideal Carnot efficiency of a thermal machine working on the same temperature drop. Numerical analysis of the system has been performed developing a Fortran™ code in a Eulerian framework, using a mixed Fourier-Galerkin/finite difference spatial discretization. The harvester is suitable for producing electricity from running engines, appliances, warm gas exhausts, exothermic processes.

Digital manufacturing of electrically conductive lines on flexible, soft polymers represents a key step for the 3D integration of electronic devices. Yet, the trade‐off between throughput and performance, once substrate and conducting materials have been fixed, is an often‐missing step in literature. Here, Ag conductive lines printed on a soft polymer are realized by means of piezoelectric inkjet printing, and three printing methods are compared to benchmark their output: drop on position, print on fly, and shingle method.

A liquid-state pyroelectric energy harvester is described and a remarkable capacity to convert a thermal gradient into electrical energy is demonstrated. Increasing the sustainability of energy generation can be pursued by harvesting extremely low enthalpy sources: low temperature differences between cold and hot reservoirs are easily achieved in every industrial process, both at large and small scales, in plants as well as in small appliances, vehicles, natural environments, and human bodies. This paper presents the assessment and efficiency estimate of a liquid-state pyroelectric energy harvester, based on a colloid containing barium titanate nanoparticles and ferrofluid as a stabilizer. The liquid is set in motion by an external pump to control velocity, in a range similar to the one achieved by Rayleigh–Bénard convection, and the colloid reservoir is heated. The colloid is injected into a Fluorinated Ethylene Propylene pipe where titanium electrodes are placed to collect electrical charges generated by pyroelectricity on the surface of the nanoparticles, reaching 22.4% of the ideal Carnot efficiency of a thermal machine working on the same temperature drop. The maximum extracted electrical power per unit of volume is above 7 mW/m3 with a ΔT between electrodes of 3.9 K.

Nowadays, energy-related issues are of paramount importance. Every energy transformation process results in the production of waste heat that can be harvested and reused, representing an ecological and economic opportunity. Waste heat to power (WHP) is the process of converting the waste heat into electricity. A novel approach is proposed based on the employment of liquid nano colloids. In this work, the triboelectric characterization of TiO2 nanoparticles dispersed in pure water and flowing in a fluorinated ethylene propylene (FEP) pipe was conducted. The idea is to exploit the waste heat to generate the motion of colloidal TiO2 through a FEP pipe. By placing an Al ring electrode in contact with the pipe, it was possible to accumulate electrostatic charges due to the triboelectric effect between the fluid and the inner pipe walls. A peristaltic pump was used to drive and control the flow in order to evaluate the performances in a broad fluid dynamic spectrum. The system generated as output relatively high voltages and low currents, resulting in extracted power ranging between 0.4 and 0.6 nW. By comparing the power of pressure loss due to friction with the extracted power, the electro-kinetic efficiency was estimated to be 20%.

Tubulin is a key protein of the cytoskeleton, forming networks of microtubules (MTs). These networks are vital for many aspects of a cell, including intra-cellular transport. It has been suggested by others that this network could be responsible for sub-cellular information processing, which naturally raises the question of whether such a system could be exploited for more artificial constructs. In this endeavour, this paper studies the electrical properties of Taxol-stabilised MT ensembles. Electrical experiments were conducted on samples containing MTs. Measurements were made using iridium-coated needle electrodes on a droplet. Cyclic voltammetry was performed, by sweeping through a DC voltage range of [-1.2,+1.2] V. AC measurements were also taken, between 1 kHZ and 10 MHz, and with a DC bias. Separately, pulse train stimulation were conducted, with an amplitude of 0.5 V and duration of 1 ms. Cyclic voltammetry experiments reveal that the MT droplets act as electrical switches, under the experimental conditions. This is partly revealed in a substantial hysteresis. The stimulation of a MT droplet with a positive fast-impulse resulted in oscillation of the droplet’s resistance, not observed in control experiments. Taxol-stabilised MT samples proved to be mem-resistive/mem-inductive, therefore the history of their electrical characterisation is able to change their response and behaviour. If the history of electrical stimuli is the same, so is the response. These findings pave a way towards future designs of MT-based sensing and computing devices, including data storage featuring liquid states.

Liquid cybernetic systems with embodied intelligence solutions mimicking biologic systems, in response to future increasingly distributed sensing and the resulting data to be managed, has been proposed as the next cybernetic paradigm. Storing and computing information inherently pushes research toward extremely high packing densities, shifting from classical into quantum (particle, molecular) physics, chemistry, and materials science with the drawback of requiring very expensive equipment and exotic matter or matter states. Solutions represent a cheap and easy‐to‐handle platform for data storage and readout in liquido, where a physical structure able to change configuration under electrical stimuli reversibly exchanges entropy with the external environment. Tectomers are proposed as a candidate for such an adaptive structure. A tectomer is an oligomer made of few oligoglycine units with a common center. Tectomers undergo pH dependent assembly to form a single layer supramer across a surface. Tectomers represent a stable paradigm, in their amorphous or crystalline forms, reversibly influenced by solution pH, whose electronic properties are studied herein. Through a reasonable hypothesis, how solvated cybernetic systems can be exploited in the rush for zettascale computing will be looked upon.

This article reports on the effect of silver nanoparticles (NPs), used as active fillers, on the piezoelectric response of polymer composites. In particular, it is demonstrated that the application of a periodic electric field drives a collective drift of surface atoms of the NPs along the field direction (“electrokinetic effect”) which, in turn, creates macroscopic reversible tensile states. Overdriving the system, in high‐field conditions, the electronic current is counterbalanced by a massive injection of Ag+ ions into the matrix, producing a metastable exceptional expansion of the device. For similitude with the converse piezoelectric effect, it has been called the converse piezo–electro–kinetic effect. By using in situ spectroscopy, vibrometric analysis, real‐time UV‐visible spectroscopy, in situ electrical transmission electron microscopy, and in qualitative form ab initio and finite element method numerical simulations, i) the injection of ions from the NPs to the matrix, ii) the surface migration‐induced NP reshaping, and iii) the NP migration and consequent percolation path adjustments are shown. The implications of this study are significant for the development of ultrafast soft ionic actuators and create the premises for a broad range of applications in smart materials and devices.

Electron devices are components used in ICT where information is encoded in the electronic charge channel. Among them, those manufactured through digital printing, benefited from a tremendous research effort for the creation of a palette of functionalities provided by solution processed materials, to achieve dielectric, metallic and semiconductive behavior. The degree of metallicity of available printable inks very seldom goes below the threshold of 200 mΩ/□ which is fundamental for the fabrication of high quality conductors. Here we describe the formulation of a ink, based on Diamine Silver(I) Carbonate, Ammonium Formate and Polyols, providing several physicochemical characterizations and describing the process leading to sheet resistance below 200 mΩ/□ after a annealing at 120 °C for 5 minutes.

Resistive switching devices are considered as the most promising alternative to conventional random access memories. They interestingly offer effective properties in terms of device scalability, low power-consumption, high read/write operation time, endurance and state retention. Moreover, neuromorphic circuits and synapse-like devices are envisaged with resistive switching modeled as memristors, opening the route toward beyond-Von Neumann computing architectures and intelligent systems. This work investigates how the resistive switching properties of zinc oxide thin films are related to both sputtering deposition process and device configuration, i.e. valence change memory (VCM) and electrochemical metallization memory (ECM). Different devices, with an oxide thickness ranging from 50 to 250 nm, are fabricated and deeply characterized. The electrical characterization evidences that, differently from typical nanoscale amorphous oxides employed for resistive RAMs (HfOx, WOx, etc..), sub-micrometric thicknesses of polycristalline ZnO layers with ECM configuration are needed to achieve the most reliable devices. The obtained results are deeply discussed, correlating the resistive switching mechanism to material nanostructure.
