IIT Bhubaneswar creates wearable sensing system to track health

Scientists of IIT Bhubaneswar have developed a flexible and wearable sensing system to track human health.

The research team of IIT Bhubaneswar has come up with a flexible and wearable sensing system that uses light to take a precise reading of human health. The wearable patch can read pulse rate, temperature, and bending or stretching measurements of the body and it can easily be put on any part of the body. The IIT Bhubaneswar's team of scientists is now working to add a blood pressure check feature in it.

"Wearable electronics devices have advanced significantly, but their accuracy and longevity have been largely limited. Alternatively, flexible and wearable optical sensing systems hold the potential to overcome such challenges while satisfying the user needs," said Rajan Jha, physics professor of IIT Bhubaneswar, as reported by TOI.

"We are introducing a fully bendable and wearable sensor that is capable of measuring body temperature, joint bending in different directions, and tracking limb activities, facial motions, respiration and pulse rate," said Jha, who is heading the work in IIT Bhubaneswar at Nanophotonics and Plasmonics Laboratory in School of Basic Sciences.

Wearable patch can measure multiple parameters accurately

He also added that as the patch measures parameters based on light rather than current as in electronic devices, the measurements are more accurate.

"We are currently extending our technology's capabilities to detect multiple physical properties over a wider range by changing factors such as the structure of the optical fiber, the coating on the probe area, and using biodegradable/biocompatible materials to make the system environment-friendly and sustainable," said researchers Pratik Mishra, Subrat Sahu and Kalipada Chatterjee.
