Abstract: Piezoelectric energy can be gathered from rapid pressure changes, such as those applied to keyboards when typing. A piezoelectric array is embedded within a removable keyboard cover that slides to fit any keyboard configuration (i.e. any machine with buttons). The array is attached to a battery that can store energy for future use. The battery is attached to an outlet to distribute power gleaned from the battery and to an internal lighting mechanism within each key of the keyboard cover. A regulator for the battery in the form of a switch may be used to control energy flow.
