What is Self-Powered Sensor for Composite Impact Detection about?

This document describes a study that developed a self-powered triboelectric sensor to detect impacts in composite structures. The sensor uses polyvinyl fluoride and polyvinyl pyrrolidone nanofibers as triboelectric materials. Composite plates were subjected to impacts from 2-30 J using a drop weight machine. The triboelectric sensor measured the electric responses in terms of voltage and current. Results showed that the electrical signals increased linearly with impact energy, demonstrating good sensitivity
