The present invention provides a paper-based self-powered sensor patch for glucose monitoring in sweat and for the prevention and management of exercise-induced hypoglycemia.


The technology demonstrates the sensing concept for self-powered, wearable, and disposable glucose monitoring in sweat. The fuel cell-based sensor is composed of three functional layers: the anodic layer with a conductive reservoir, the sweat reservoir, and the air-cathode layer. When attached directly to human skin, sweat is wicked by using capillary forces and monitored an electrochemical current generation as a transducing output signal for glucose monitoring in sweat. Thus, it eliminates the requirement of exterior batteries and advances readout instrumentation.
