Interdisciplinary researchers from Chinese universities have developed a miniature continuous glucose monitoring system using an organic electrochemical transistor (OECT) with a microneedle array and hydrogel. The system, comparable to market-leading devices like Dexcom G6, promises enhanced sensitivity, reliability, and wearability. OECTs operate in aqueous environments at low voltage with low power consumption, making them ideal for detecting weak biosignals. The researchers plan to advance their system for clinical use. In the market, Chinese companies SiBionics and Zhejiang POCTech offer CGM systems, while Dexcom is releasing the G7 with Bluetooth connectivity to the Apple Watch. Singapore introduces a hydrogel-based sensor for monitoring diabetes and heart conditions.
