Abstract
Piezoelectric energy system is one of the technology for clean energy production that
generated electrical energy from mechanical force from human locomotion. However,
this self-powered technology are not fully studies as the percentage of natural resources
depletion increasing each day. In Malaysia, the development of piezoelectric technology are
very limited due to the lack of study in utilization of waste energy from human locomotion.
Thus, this work is required to design and fabricate a smart energy reflexology tile using
piezoelectric to produce electrical energy from mechanical energy as well as to investigate the
performance of piezoelectric tile design in harvesting footsteps energy. A prototype of
piezoelectric reflexology tile is developed to measure the voltage generation and power
produced from human locomotion. Factors that involved throughout the projects are weight of
subjects exerted on it, the stepping speed, number of piezoelectric used and circuit arrangement.
The data collected is then used to analyse the performance of piezoelectric tiles in harvesting
energy. In conclusion, the piezoelectric tile with reflexology mat and attached with four
piezoelectric disks connected in series-parallel connection is able to produce the highest voltage
up to 5 V contributed by 88 kg subject. Each disk can produce power up to 0.07 mW after
connected to other electrical components like resistor. Besides that, this work also able to
produce power up to 10Mw. However, in order to increase the energy supply to supply more
power to electronic devices like wireless sensors, equipped with high harvesting circuit system
to ensure large power can be generated and the involvement from higher capacity of people are
required to step on the piezoelectric tiles with reflexology mat.
