JODHPUR, March 21 -- Researchers at the Indian Institute of Technology (IIT), Jodhpur are developing next-generation flexible semiconductor devices for continuous health monitoring, early disease detection, and physiological assessment in demanding conditions. The work is being carried out at the Hybrid Electronic Sensor Technologies (HESTECH) Lab, led by Dr Akshay Moudgil, assistant professor in the department of electrical engineering. The research focuses on soft, flexible, and intelligent semiconductor devices that can monitor important physiological and biochemical signals from the human body in real time. These wearable sensors are designed to measure parameters such as heart rate, muscle signals, body temperature, and skin pressure while remaining comfortable for long-duration use. "Across India and the world, many health conditions are detected too late because continuous monitoring remains limited outside specialised settings. Our goal is to develop semiconductor devices that can monitor body signals continuously and comfortably, so that early warning signs can be identified and acted upon in time," said Dr Moudgil. A key component of this work is the Organic Electrochemical Transistor (OECT), a class of semiconductor device particularly well suited for interfacing with biological signals and fluids, he said. Unlike conventional rigid electronics, OECT-based platforms can support both electrical and biochemical sensing in flexible formats. The HESTECH Lab is developing low-power wearable sensors using biocompatible hybrid semiconductor materials that can be fabricated on thin, flexible substrates. This makes them suitable for skin-conformal devices for continuous and non-invasive monitoring. "Our work is exploring whether a single semiconductor platform can capture both the electrical activity of the body and biochemical signatures linked to disease. Using OECT technology, we are building flexible devices for monitoring heart activity, muscle response, and disease-related biomarkers in a compact and wearable format," explained Dr Moudgil....
