Jiacun Sun · 2012
When under pressure, the piezoelectric materials produce electric charge on its surface, the foot continuously produce pressure on the earth when human is walking, if the shoes fitted with piezoelectric ceramics, piezoelectric ceramics is continuously under pressure, and Continuously generate charge, The electrical energy is stored by the electrical energy storage circuit, after be stabilized, the electrical energy can recharge the rechargeable battery.This paper studies the body acquisition principle of the piezoelectric ceramic energy, the piezoelectric ceramic energy acquisition experimental setup is designed, the device structure is simple, experiments were carried out, and experimental results show that the device is ideal for charging to the mobile electronics, power or other portable medical devices power.
