Abstract:

This paper presents a design idea for an electric charging device designed to sit underneath the keypad of various mobile devices using piezoelectric and similar effect materials. It discusses the benefits of such a device and the current problems associated with developing one. The basis for the device is that multiple piezoelectric materials placed under the keypad are subjected to repeated loading from activities such as 'texting' or 'menu browsing'. This causes a variable voltage generation which can assist in charging or other suitable function of the device. The paper shows the ways to achieve this goal and examine current piezoelectric generators. Copyright © 2009 by ASME.
