In a major step toward transforming diabetes management, researchers at the Indian Institute of Technology Madras (IIT Madras) have developed and patented a low-cost, user-friendly, and minimally invasive glucose monitoring device designed to make diabetes care more comfortable and accessible for millions of patients.

The innovation, from the Electronic Materials and Thin Films Lab led by Prof. Parasuraman Swaminathan, reimagines continuous glucose monitoring (CGM) technology to offer a pain-free experience without the prohibitive costs associated with existing imported systems.
- Patented device offers pain-free, cost-effective alternative to finger-prick tests and costly imported CGMs
- Innovative modular system combines reusable electronics with disposable microneedle sensor patch
- “Success is when research truly improves lives,” says lead scientist Prof. Parasuraman Swaminathan
According to the Indian Council of Medical Research – India Diabetes (ICMR-INDIAB) study (2023), over 10.1 crore Indians live with diabetes, making affordable monitoring solutions a critical healthcare priority.
Unlike traditional Self-Monitoring of Blood Glucose (SMBG), which requires frequent finger-prick tests, CGMs provide real-time glucose readings. However, current CGM models remain expensive and reliant on smartphones or dedicated display units.
To overcome these limitations, the IIT Madras team developed a modular device that integrates reusable electronics and a low-power display with a disposable microneedle sensor patch, providing both affordability and accuracy.
“From a researcher’s perspective, the real measure of success is when an idea steps out of the lab and makes a tangible difference in people’s lives,” said Prof. Swaminathan. “In diabetes management, that difference could mean sparing someone the discomfort of multiple finger pricks a day and preventing long-term complications.”
The IIT Madras innovation—now protected by multiple patents—represents a vital leap in making continuous glucose monitoring accessible to the common man, bridging the gap between advanced medical technology and everyday healthcare needs.
