Robust superhydrophobic wearable piezoelectric nanogenerators for self-powered body motion sensors

The self-powered piezoelectric nanogenerator (PENG) sensor is superhydrophobic with self-cleaning and anti-bacterial abilities, enduring 36 h immersion in corrosive liquids, 24 h ultrasonication, and 168 h high-humidity erosion. The high sensitivity, flexibility, and robustness of the sensor was then successfully integrated into shoe insoles for human gait monitoring.ga1
