Abstract: An element generating electric energy by vibration when an impact is applied, as can be described a piezoelectric sensors device. Presently, these piezoelectric sensors devices are used to power station equipment and LED lamps on bridges, where they are installed at the floor around ticket gates and bridge decks. However, one disadvantage of these piezoelectric sensors devices is that the generated electricity is too low because of little present current. Experimentally, the developed power generating shoes have been evaluated for their validity under various types of piezoelectric sensors devices, shoes and secondary batteries. Currently, it is found out that only up to 1.5% mobile phones can be charged which is indeed very low. So, we take piezoelectric sensors and after placing them in the soles of shoes, we run or walk. The energy produced by the sensors passes through bridge rectifier and gets converted to DC. The DC is stored in rechargeable battery which in turn charges the phone. To increase energy production, shoe designs should be improved and charge/discharge circuits created for them. Every day we all walk around going from one place to another. When we walk, we move forward by pushing the ground backward with our feet. Our project aims at utilizing this energy to generate electricity thus providing us with an opportunity to utilize wasted energy in earlier days hence bringing forth a ‘smart shoe’ as a step towards a modernized future.
