| However, traditional power supply equipment--batteries------still exsisting some short comings, such as big volume, limited life span, needing to take charge from time to time, etc. greatly constrains the portable electronic products application. It is believed that the effect method to solve the energy source of the low-powered portable electronic products if batteries could convert the mechanical energy into electrical energy anywhere and anytime. |
