a–g Demonstration of PEG/SIS piezoelectric sensors for wearable sensing applications. a Structural diagram and physical diagram of PEG/SIS piezoelectric sensor. b Voltage response of the PEG/SIS piezoelectric sensor under different longitudinal loads. c–g PEG/SIS piezoelectric sensor for joint bending monitoring and gait analysis. The sensor is capable of real-time monitoring of bending motions in the knuckles, elbows, wrists, and knees, as well as capturing changes in gait frequency under the sole of the foot. h, i Schematic diagram, physical diagram, and voltage response of the PEG/SIS piezoelectric sensor under different stretching strains.
