Abstract
This paper reports the design and implementation of piezoelectric mat to harvest energy from human walking and jumping activities on the mat. The mat consisted of a rubber mat loaded with an array of piezoelectric chips. These chips produced electrical voltage when receiving a pressure. Connecting these chips to a closed electrical circuit would let the electrical current flows. The current was flown to a rectifier, and the respective electrical charge could be collected in a super capacitor. The module was also complemented with a human machine interface to monitor the capacitor�s voltage. This application was programmed in Java platform and was integrated with a serial communication RS232 and a microprocessor that function as a data acquisition module. Evaluation of the overall module consisted of chip characteristic, capacitor charging and discharging. The chip characteristic test helped to select the piezoelectric type t use underneath the carpet. The selected chips were covered by resin to protect them from excessive pressure. The ability to charge capacitor was tested by performing walking and jumping on top of the carpet in 5 minutes. These activities generated in 1.1V potential at the capacitor. Varying and intensifying these activities produced 3V and managed to light of � Watt LED. On the other hand, the time constant of capacitor discharge was 76.92 minutes.
