Wearable sensors using PU - Developed in India

Dr Dipti Gupta from IIT Bombay has developed low-cost soft, flexible, and wearable sensors with potential applications in robotics, prosthetics, as well as minimally invasive surgery and identification of tumour/cancerous cells. A very simple, low-cost approach was found for the fabrication of a pressure sensor based on polyurethane (PU) foam coated with the graphene-silver composite ink for highly conductive wearable electronics applications. The technology which can be used to monitor the pulse waveform of a human radial artery in real-time is aligned with the 'Make in India' initiative, and Dr Gupta has applied for 3 national patents for these sensors.
