India Unveils Non-Invasive Glucose Monitor Using EM Technology

By analyzing changes, the device accurately determines the glucose level, all by using electromagnetic technology and without a drop of blood being drawn.

Researchers at MNNIT Prayagraj, in collaboration with Dr Ram Manohar Lohia Institute of Medical sciences, Lucknow, have developed a glucose monitoring sensor that does away with painful needle pricks.

The innovation was developed by researchers from the Department of Electronics and Communication Engineering (ECE) at MNNIT, including Professor VS Tripathi and his research students, in partnership with Dr Shiv Shankar Tripathi and Dr Swagat Mahapatra from RMLIMS.

By analyzing changes, the device accurately determines the glucose level, all by using electromagnetic technology and without a drop of blood being drawn.

The research was published in the Defence Science Journal and the technology has also received a patent and the project also received financial support of INR 8.94 Lakh from the Council of Science and Technology, Uttar Pradesh.

According to scientists, electromagnetic waves travel from one medium to another, and by measuring changes in frequency, the sensor can detect glucose levels by reading the dissolved sugar level in the blood between the skin and flesh.

Tripathi said, “We just connect the device and the changes in the frequency of the electromagnetic waves will provide the precise reading without a single prick or any pain thereof.”

The sensor is designed to be placed between the thumb and first finger and has two parts. The sender emits radio waves, which pass through the skin and are then captured by the receiver.

Then, by analyzing changes in the electrical frequency, the device accurately determines the glucose level, offering continuous glucose monitoring and making diabetes management easier.

According to Tripathi, the technology will be especially useful for patients who require frequent monitoring, as it allows for real-time tracking and timely treatment.

Additionally, the sensor is also designed to be cost-effective with an expected retail price of not more than INR 500, making it easily accessible for the lower-income groups.
