چکیده
A 2015 NRDC research study revealed that electronic devices consume alarming amounts of energy. To reduce theenergy consumption these devices, this project proposes a novel energy-harvesting keyboard design allows acomputer to charge as the user types on it. The generates electricity via piezoelectric materials. novelkey structure and transducer circuit were proposed integrate piezo materials in transform theelectricity generated through keystrokes into usable form. prototype with 9 keys was used for testing.Data collected two rounds; first round tested power per keystroke. It determined thatthe average from single key press 0.342 μW. second testing involveddetermining after typing at constant rate 5-25 seconds. peak electrical output occurredat 25 seconds typing, during which total 2.38 mW. Thus, typing,62% 22μF capacitor can be charged. This is nearly times higher than theexpected output. Given expected value calculated using higher-quality one usedin prototype, it concluded significantly increased generated. Althoughthe needs computer are not fully met, may applied hybrid charging system utilizing boththe plug-in charger keyboard.
