The mechanical stress applied on the touch screen of cellular phone while using is converted to electrical energy using the proposed transparent piezoelectric transducer. The location of the transducer is proposed for its attachment at the back of the cell phone screen. Though it may not generate enough power for successful running of the cellular phone, the method generates sufficient amount of power for automatic and gradual cell phone charging. The charging through such proposal increases the battery life of the cellular phone for longer use time. Copyright@ International Science Community Association
