Worldwide, around 50 million people have dementia with symptoms including loss of memory, difficulty in thinking ability, issues with problem-solving and usage of language. About 1.2 million people provide specialised care for dementia patients throughout the world, but the number of trained dementia caretakers are low in India. Traditionally, the focus of medical research has been to find a plausible cure for dementia, while solutions to ease the lives of dementia patients, their caretakers, and their families are often neglected. This paper aims to design and develop a bio-engineering based assistive device- Memhans for patients suffering from the mild and moderate stage of dementia through the help of a case study, intensive design methodologies and prototyping skills. The prototype is an RFID based module integrating a GPS chip (for location tracking) with Bluetooth and a smartwatch app which has the function of relaxing the patient with music. It also provides notifications to the patient, their family, and their caretaker via respective smartphone apps and provides for a contextual understanding by ‘object and person identification’. This device provides the patient with assistance in daily activities, safety, person and object identification, and most importantly helps them live a dignified life. It also gives a sense of security and eases the minds of the caretaker and the patient's family. This device is cost-effective and is developed for a large number of impoverished patients who reside in developing countries like India.

Design thinking (DT) can be a valuable tool for nurturing problem-solving abilities in school children. The objective of the paper is two-fold. The first is to evaluate the effectiveness of the DT process as a potential tool for open-ended problem-solving for school children; the second is to test the effectiveness of gamification of the DT process in terms of the extent of comprehension and learning of the process enabled by gamification. The paper presents a framework for IISC, a Design Thinking Process developed by the authors, and compares two gamified models of the DT process against one another using empirical studies that involved school children in the age-range of 14 to 18 (8^th to 12^th years of their twelve years of school education) playing the games. Feedback from the students and their mentors during the game was used as data for evaluation. The paper also discusses the limitations identified and suggested improvements of the two gamified models, and implications of these for designing more effective games.

Modern 3D printing techniques enable the rapid prototyping of complex mechanical structures. We leverage this capability to create customizable pressure sensors by combining soft and ferromagnetic filaments during the printing process. The resulting inductive sensors utilize a lattice structure based on a body-centered cubic unit cell, exhibiting tunable stiffness with Young's moduli ranging from 112 kPa to 368 kPa and sensitivities between −0.17% kPa−1 and −0.11% kPa−1. The sensors show minimal hysteresis and remain stable throughout 10000 compression cycles. The versatility of this approach is further demonstrated through the fabrication of a fully printed inductive joystick
