While walking our human legs will make some pressure under the feet. With this concept I made this mini project.
Piezoelectric disc that converts vibration to electric current and when electric current passes the disc get vibrates. I fix this disc in my shoes and my foot make pressure when I tends to walk. Presented this as my first year project in Sharp'15 at Coimbatore on January 2015.
Output : AC
Power : 0.5 Amps & 1.5- 3.7 volts
