New research describes the first example of self-powered bioelectronics on a mask that can measure the biological glucose signal with continuous energy. In their work, the researchers demonstrate a 3-in-1 mask device that can 1) harvest energy (a biofuel cell); 2) store energy (a supercapacitor); and 3) indicate glucose concentration (a biosensor). The small biofuel cells can harvest energy from the sweat on a person's face and indicate the level of the analyte that tracks health and ...
