Abstract
This study examines the suitability of piezoelectric floor mat systems for harvesting energy in high traffic areas like the student centers. The study is aimed at solving the problems of small energy production, toxic materials and the ability to scale up current piezoelectric energy harvesting systems. The study involves experimental simulation of using 40 piezo transducers, a 2W02G rectifier, two 2F, 5.5V super capacitors for energy storage, an ND0603PC booster amplifier for output regulation and two LiPo batteries in series, to supply stable power to a case study Centre. Both the supporting circuit diagram and MATLAB/Simulink simulation were utilized to show that this system works well for independent power generation. Simulations and tests on circuits reveal that the system delivers an average output power greater than the required standard, 400–600 μW per step versus 134.2 μW per step. Rectifying the energy from 1,000 steps yields AC voltages varying from 20–80V which are then changed to DC at 18–75V. At the beginning, the super capacitors charge with 5–6V to last for 10–30 seconds before leveling off at 3.7–5.5V and the LiPo batteries provide about 5–20 mAh after being active for 10 minutes. Trials show that the device produces constant electricity under various stress tests, showing good conversion, storage and release of energy for powering small electronic devices. The results confirm that piezoelectric floor mats can be used affordably to produce energy anywhere in busy areas, thereby aiding efforts to make urban environments and the planet more sustainable. In the future, more experiments and improvements are required for deploying the technology on a wider scale.
