Researchers Develop Wearable Devices for Stress Detection, Skin-Powered Tech

Researchers at Carnegie Mellon University have introduced Power-Over-Skin technology, which allows electrical currents to travel through human skin to power low-energy devices like blood sugar monitors and smart wearables. This innovation utilizes complementary, internal, ion-gated organic electrochemical transistors that are more compatible with living tissues compared to traditional silicon-based electronics, presenting a significant advancement in bioelectronics. The study from UC Irvine highlights the design of these transistors to interact with biological systems, ensuring biocompatibility and flexibility essential for medical applications. Additionally, a team from Jawaharlal Nehru Centre for Advanced Scientific Research has developed a novel wearable device that mimics human pain perception, allowing it to adapt its electrical responses to stress, which could lead to advanced health monitoring systems. These developments indicate a shift towards integrating electronics more harmoniously with the human body, potentially paving the way for future medical and consumer applications. Overall, these innovations represent a step toward creating more responsive, biocompatible electronic systems.
