Pengisian Baterai Handphone berbasis Piezoelektrik

Abstract

Handphone is a recently communication device that is used in daily life. The application of handphone certainly can reduce the resource of battery continuity. It makes the practices characteristic of handphone is decreased because user needs AC resource to recharge the battery on one condition. By adding the DC-DC converter, piezoelectric can be usefull as recharging battery that can be used in emergency condition. Based on measurement dan examination, the value of voltage’s piezoelectric is varied (can be changed) because the energy of mechanic that accepted by piezoelectric is varied too, when it is influenced to the mass of something. The energy of electric that is produced from piezoelectric is only temporary, piezoelectric will produce the energy of electric while it gets the frequence (pressure). The value of op-amp output of voltage is not bigger than it’s saturation voltage. The measurement of output voltage of boost converter has reached above 5 Volt. The boost converter circuit will be used if the input of voltage have to bigger than or same with 3 VDC. The conclusion is the battery charging of handphone system based on piezoelectric, by using diode circuit, op-amp, and boost converter with applied in the shoe. The energy of electric that is produced from peizoelectric can be used as the alternative of resource in emergency condition, but the of recharging battery needs a longer time, because the current that is produced of piezoelectric still a little bit, although the voltage has been reached the wanted value.
