Abstract

Almost everyone uses a handheld device (cell phone). What makes our device so important, is that it provides mobile device charging convenience as compared to current stationary charging methods. With this in mind, is it truly possible to harvest enough energy from walking to charge a hand held device? We realized a specific experimental implication from the theoretical literature. We used a piezoelectric actuator and connected it to a full wave rectifier circuit to convert the AC electricity to DC electricity. Then, we lit up LEDs and charged capacitors and rechargeable batteries. Our results demonstrated that it is possible to charge a hand held device while walking. We were able to charge a 250 microfarad capacitor to 20 volts, which corresponds to an energy of 0.05 joules.
