A “fully integrated, wearable” continuous glucose monitor (CGM) is set to transform diabetes care, researchers have said.
Scientists from the University of Hong Kong, Zhejiang University and Guangzhou Medical University have developed a new CGM that is set to have better anti-noise ability, reliability, and wearability compared to other devices.
Entitled ‘OECT-CGM’, the compact, coin-sized device features hydrogels, minimally invasive tools and state-of-the-art biosensors.

The organic electrochemical transistor (OECT) is the main part of the device which enhances the signal-to-noise ratio (SNR) beyond traditional electrochemical sensors.
According to the researchers, this feature provides accurate and reliable glucose readings which is extremely beneficial for good diabetes management.
The device includes a microneedle array for subcutaneous glucose sampling, as well as a viscoelastic and diffusive hydrogel.
First author Professor Shiming Zhang said: “This fully integrated, wearable device promises enhanced anti-noise ability, reliability, and wearability compared to traditional CGMs.”

In the future, the team will explore the device’s potential applications in various health care settings.
Professor Zhang said: “This groundbreaking work not only showcases the innovative capabilities of the research team but also sets a new standard for wearable health monitoring technology.
“The team’s dedication to improving the quality of life for individuals with diabetes is evident in this remarkable achievement.”
