Abstract/Executive Summary
Nowadays, nanogenerators are being developed to be alternative renewable energy sources by harnessing energy from ambient vibrations and mechanical motions. From this, several state-of-the-art designs have hybridized piezoelectric nanogenerators (PENGs), triboelectric nanogenerators (TENGs), and electromagnetic generators (EMGs) for integration into tiles, pavements, and shoes to capitalize on the biomechanical energy exerted from human footsteps. However, existing devices featuring hybridized nanogenerators lack the ability to harvest bulk mechanical energy while being portable simultaneously. Hence, this research aimed to design a portable triple hybrid piezoelectric, triboelectric, and electromagnetic portable mat generator that could harvest ambient mechanical energy from multiple sources at once. The constructed device, “Pow3rSteps,” was capable of being folded for easier transportation and deployment at various locations and was composed of 6 modules, each with 6 PENGs, 2 TENG stacks (a total of 8 TENG pairs), and 2 EMGs. When compared to an existing study that featured the same types of generators implemented in a shoe design, one module of the mat was found to produce 156% more peak voltage, 53.56% more peak current, and 212.56% more peak power. Meanwhile, in terms of energy storage for the whole device, it was found that it could store up to 6.88 V in 10 seconds when stepped on at 120 BPM by a 60 kg person. Overall, the results from this device indicate its potential as a sustainable alternative source of renewable electricity that paves the way for the creation of future hybridized nanogenerator technologies.
