Figure 11. LIG-based biochemical skin electronics with multiple sensing modes for intelligent healthcare. (A) Layered view of the sensor structure; (B) Schematic illustrating various functions of the integrated sensors, including sweat UA and Tyr monitoring, sweat rate evaluation, skin temperature perception and vital-sign (for instance, heart rate and respiration rate) detection; (C) Optical photographs of a healthy subject wearing the sensing system at different body positions; (D) Real-time measurement results of multiple physiological signals from a healthy subject during a control exercise process.
