In today's hectic lifestyle, health has been seriously hampered due to sedentary work. This paper represents an idea of walking based wearable piezoelectric device that provides an alternate means for powering mobile phone batteries. Moreover, it simultaneously serves another purpose of providing an emergency torch. Since, the mechanism of the device is based on walking; the device promotes human metabolism as well as physical fitness. Hence, it can be seen as an e-health gadget that encourages walking exercise as a means to power emergency torch and mobile phone batteries. The portable device comprises of a piezoelectric power generator, connectors for charging different mobile phone batteries and a Light Emitting Diode (LED) embedded in shoe for providing emergency torch. Piezoelectric circuit harvests energy from user's trotter movement. This energy is amplified, rectified by using a DC convertor and then regulated to 4.2 volts which is required by a Li ion mobile battery. By using this device, a man weighing 60 Kg can charge a 800mAh capacity battery in 2.6 hours by normal walking.
