System and method for a power sustainability keyboard with piezoelectric energy harvester device

A wireless keyboard comprising:

• a wireless keyboard microcontroller;
• a wireless keyboard radio to wirelessly communicate with a host information handling system;
• a power management unit (PMU) to provide power to the wireless keyboard microcontroller and the wireless keyboard radio, the wireless keyboard PMU operatively coupled to a battery and an ultracapacitor, wherein the wireless keyboard PMU switches between the battery and the ultracapacitor to power the wireless keyboard;
• a piezoelectric energy harvester device having a fixed end and a displaceable end of a piezoelectric material diveboard structure operatively coupled to the ultracapacitor and placed under a first key formed on the wireless keyboard to charge the ultracapacitor when the first key is actuated by a user, where the displaceable end of the piezoelectric material diveboard structure is flexed with actuation of the first key;
• the wireless keyboard microcontroller, to determine when a threshold time period has expired since a user has last actuated a key on keyboard based on the keyboard engagement data received to the wireless keyboard microcontroller and place the wireless keyboard in a standby mode and the wireless keyboard PMU to switch power to the ultracapacitor from the battery in the standby mode;
• and
• the wireless keyboard microcontroller to detect when a key on the wireless keyboard is actuated based on input from an actuation/engagement sensor and provide keyboard engagement data to the wireless keyboard microcontroller indicating presence of the user to switch power from the ultracapacitor to the battery.
