3D Porous Stacked Organic Electrochemical Transistor for Wearable Glucose Sensing: Enhancing Comfort, Breathability, and Real-Time Monitoring

With an excessively indulgent diet and irregular routine, diabetes has emerged as a pervasive and life-threatening chronic condition. Real-time monitoring of glucose levels and stringent glycemic control are imperative for the efficient prevention and management of this ailment. Organic electrochemical transistors (OECTs) have attracted significant attention owing to its mechanical flexibility and its property to operate effectively in aqueous environments. Herein, a wearable glucose sensor is developed via ionic solutions as well as for the enzyme-based detection performance. Taking inspiration from nature, we have innovatively designed a 3D porous stacked OECT to attain passive cooling and enhanced breathability, ensuring an improved and comfortable wearing experience. The device has proven successful in detecting glucose concentrations within artificial sweat, paving the way for the development of next-generation sensors.
