Abstract/Executive Summary

Energy is one of the necessities in life. The Philippines has abundant energy resources; however, as the energy demand increases, energy reserves are diminishing faster than they can be replenished, and alternatives remain underutilized due to cost and ethical challenges, resulting in a shortage in energy production. To combat this, bio-piezoelectricity, which transforms mechanical forces into electrical energy through an organic material, offers a secure substitute for current energy resources. This study aims to determine the efficacy of queen pineapple crown leaves (QPCL) as a bio-piezoelectric generator in energy generation, harvesting, and conversion efficiency. The leaves served as the primary material of the three (3) fabricated QPCL-BPEG, designed to absorb applied force and convert mechanical energy to electrical energy, measured in voltage. Each QPCL-BPEG is subjected to varying weights, ranging from 0 g to 100 g, until maximum voltage is reached. Subsequently, the measured voltage output of the QPCL will be compared to the voltage output of biologically-based, specifically those of plant waste fabricated piezoelectric generators. The results revealed a maximum voltage output of 1.57 V using a 1 kg mass on the QPCL-BPEG, and a minimum output of 62 mV produced without any weight force. Thus, these results suggest that QPCLs may be a viable energy source through a bio-piezoelectric fabrication process for energy generation, harvesting, and conversion efficiency despite the lower output compared to other biological-based BPEGs.
