“…Human power is a viable source which can be used to charge cell phone devices, transformation can be extracted by piezo electric material. However, number of significant contributions are done like key pressing on cell phone [1], Hand crank generators [5], to name few. A prototype was also suggested named as Human Powered Contactless Charger for CellPhones (HCCC),the device includes a Human Power Harvester (HPH) and a Receiving Unit (RU) along with gears and clutch as shown in the Figure 1.…”

Micro-scale energy harvesting solutions are highly demanded globally in almost every field.Specifically, when it comes for a cell phone battery life. The imbalanced situation between battery technology and cell phone evolution is getting worse. However the efficient system is needed which is able to charge a cell phone when we are off from the power source.The researchers put forwards the attention towards the readily available energy sources to be harvested for charging purpose.For making such efforts, number of solutions have been proposed but many hurdles lies in it which includes the design, compatibility and most importantly the different parameters of every cell phone device.This paper demonstrates the specifications of different cell phone models and a datasheet is produced which includes the minimum output power requirement during standby and talk time.

Frequency Scaling based energy efficient MBCCS is implemented in this paper. In this design, if battery's voltage or current is less than threshold then battery will continue charging. Whereas, if voltage or current is more than threshold then it will ring Overcharge Alarm. With Frequency Scaling, we reduce frequency from 1THz to 25GHz, where 125GHz, 625GHz are intermediate frequency value. There is 97.50%, 100%, 97.54%, 97.48%, 20%, 96.48 % reduction in clock power (CP), logic power (LP), signal power (SP), IOs power (IOP), leakage power and total power dissipation respectively when we scale down frequency from 1 THz to 25GHz.
