Due to the recent advancement in wireless technology, the demand on power sources has increased dramatically. Personal electronics like cell phones, mp3 or electronics devices like wireless keyboard, both are dependent on batteries as the source of energy. However, with the ever-shrinking electronics, existing battery technology imposes a limitation on size, weight and often times maintenance. Technology like energy harvesting from ambient sources like solar or vibration is believed to play a critical role in these devices and can act as power source for uninterrupted operation. In this paper we discuss, energy harvesting from personal devices like cell phones or keyboards. Since, most of the signal generated is in the form of pulse, an energy harvesting circuit for energy extraction from pulse is discussed. Conventional energy harvesting circuits for this kind of signal are also evaluated in terms of efficiency.
