Battery technologies are well established and widely used technology but they offer several disadvantages like weight, volume, large internal resistance, poor power density, poor transient response. On the other hand, due to advancement in the material and other technology, Supercapacitor or Ultracapacitors or Electrostatic Double Layer Capacitor (EDLC) are a most promising energy storage device. They offer a greater transient response, power density, low weight, low volume and low internal resistance which make them suitable for several applications. This paper summarizes recent research and development in the field of supercapacitor technology. This paper gives a brief insight into the design, characteristics and applications of the supercapacitor.

The Internet of Medical Things (IoMT) is the subset of the Internet of Things (IoT) that connects multiple medical devices, collect information/data from devices, and transmits and process data in real-time. IoMT is crucial for increasing electronic device accuracy, reliability, and productivity in the healthcare industry. IoMT has emerged as a next-generation bio-analytical tool that converges network-linked biomedical devices with relevant software applications for advancing human health. Adapting IoMT and associated technologies has fixed several problems using telemedicine, remote monitoring, sensors, robotics, etc. However, adopting IoMT technologies for a large population is challenging due to extensive data management, privacy, security, upgradation, scalability, etc. Although significant research has been carried out in this domain, identifying emerging trends and highlighting the technological advancement and challenges within IoMT is required for its success. Moreover, it will aid policymakers, scientists, healthcare practitioners, and researchers to measure the pertinence of IoMT in healthcare sectors more efficiently. This review discusses the evolution of IoMT, Machine Learning Integration, Security, and interoperability challenges of IoMT devices.

Smart shoes have ushered in a new era of personalised health monitoring and assistive technologies. Smart shoes leverage technologies such as Bluetooth for data collection and wireless transmission, and incorporate features such as GPS tracking, obstacle detection, and fitness tracking. As the 2010s unfolded, the smart shoe landscape diversified and advanced rapidly, driven by sensor technology enhancements and smartphones’ ubiquity. Shoes have begun incorporating accelerometers, gyroscopes, and pressure sensors, significantly improving the accuracy of data collection and enabling functionalities such as gait analysis. The healthcare sector has recognised the potential of smart shoes, leading to innovations such as shoes designed to monitor diabetic foot ulcers, track rehabilitation progress, and detect falls among older people, thus expanding their application beyond fitness into medical monitoring. This article provides an overview of the current state of smart shoe technology, highlighting the integration of advanced sensors for health monitoring, energy harvesting, assistive features for the visually impaired, and deep learning for data analysis. This study discusses the potential of smart footwear in medical applications, particularly for patients with diabetes, and the ongoing research in this field. Current footwear challenges are also discussed, including complex construction, poor fit, comfort, and high cost.
