Contrary to traditional planar flexible piezoelectric nanogenerators (PNGs), highly adaptable hemispherical shape-flexible piezoelectric
composite strip (HS-FPCS) based PNGs are required to harness/measure non-linear surface motions. Therefore, a feasible,
cost-effective and less-time consuming groove technique was developed to fabricate adaptable HS-FPCSs with multiple lengths.
A single HS-CSPNG generates 130 V/0.8 μA and can also work as a self-powered muscle monitoring system (SP-MMS) to measure
maximum human body part movements, i.e., spinal cord, throat, jaw, elbow, knee, foot stress, palm hand/finger force and inhale/
exhale breath conditions at a time or at variable time intervals.
