Energy Prediction Based on Periodic Mechanical Impact in PVDF-Based Piezoelectric Energy Harvesting: A Comparative Analysis of Machine Learning Models

In this study, an experimental setup was established to measure the energy that can be harvested depending on the frequency of periodic mechanical pulses using Polyvinylidene Fluoride (PVDF) piezoelectric material. The measured data were employed in Artificial Neural Network (ANN), K-Nearest Neighbo
