MICRO POWER GENERATION USING PIEZOELECTRIC TRANSDUCER INFOOTWEAR

The aim of this paper is to built a smart shoe which is equipped with power generating capability while wearing this footwear during walking and running. Because, low power consumption electronic devices have been increased rapidly in our day to day life. So, We try to develop a Piezoelectric transducer based power generation through footwear. That can produce pressure during walking or running and it convert mechanical energy into electrical energy to charge the electronic devices. Bridge rectifier was used to convert the AC voltage output from the piezoelectric transducers into DC voltage. Then it will be boost up by the dc-dc Boost converter to charge the electronic devices through Li-ion battery by using a switch. Here, a round piezoelectric disc with diameter of 3.5cm was used. Finally, the produced mean output voltage of standard 12V to charge the electronic devices such as mobile, smartwatch etc., It was a renewable source of energy and it was also a green energy.
