“…1,2 Due to the ability to realize the mutual conversion of mechanical energy and electrical energy, [3][4][5] piezoelectric materials have aroused great interest in practical applications, and are widely used in sensing, energy storage, electronics and other elds. 6,7 For example, Li et al 8 demonstrated a non-lead (ZnO) piezoelectric device powered by heart movement. Cheng et al 9 reported a self-powered PVDF sensor for blood pressure monitoring.…”
