Recent survey of the electricity board of AndhraPradesh says that the: “Energy Consumed In A Month By All Mobile Phones In Andhra Pradesh For Charging Up Is Equivalent To That Required By A Cotton Mill To Be Driven For A Year”. To counter this problem we have come up with an innovative idea to charge up the cell phone by means of nanoscale mechanical and thermal energy. A novel approach converts nanoscale mechanical and thermal energy into electric energy for self-powering nanodevices. In our own work, we've used piezoelectric zinc-oxide nanowire (ZnO NW) arrays and thermoelectric nanowires of nanoporous silicon cages to demonstrate a novel approach for converting nanoscale vibrations, room and body temperature into electric energy, which in turn could be used to charge the mobile phone. Using piezoelectric material, we could create nanowires that generate electricity from the vibrations suffered by the cell phone. The piezoelectric effect is a phenomenon certain materials exhibit in which when a physical force applied to a piezoelectric material, it emits an electric charge and vice versa. Piezoelectric nanowires might provide power to nano-size systems in the future. Thermoelectric devices can convert heat into electricity. Various researchers are working to produce inexpensive and efficient thermoelectric materials that can change waste heat into electricity. Recently there was an announcement that researchers at Berkeley had made silicon nanowires that convert heat into electricity using a thermoelectric effect. One possible use of these is to charge portable devices. The wires could be simply be knit as the panel of cell phone and thus the panel could become a charging station. Using the body temperature and room temperature as the source of energy, it could generate the electricity.
