Abstract

The increasing demand for sustainable energy solutions has led to the investigation of alternative energy sources, including wearable energy-harvesting devices. This study focuses on the development of the Piezoelectric Power-Stride Backpack (PPB), an innovative backpack that generates electricity through kinetic energy, which converts to electrical. The research examines the efficiency of embedded piezoelectric transducers in producing electrical output based on user movement and weight load. By utilizing a pre- experimental design, the study measures the energy generated under various conditions, including transducer configuration, weight, and type of movement. Results indicate that the PPB demonstrates significant potential in generating power for small electronic devices, with higher energy outputs observed under the three conditions with a p-value of 0.002, 0.033, and 0.001. Moreover, expert and user evaluations highlight the device's performance, ease of use, energy efficiency, and its overall characteristics with a mean of 3.46, 3.63, 3.63, and 0.71 (Strongly Agree). Despite some limitations in storage capacity, the PPB serves as a possible supplementary power source, contributing to the advancement of self-sustaining wearable technology. Future research should focus on the enhancement of energy storage and material optimization to maximize efficiency.
