    Hi Lavanya

    yes, it is definitely possible

    The same principle is used by EnOcean for their battery-free switches. The pressure of the finger on the switch is converted by a piezo-electric component to energy that powers up the RF transmitter.

    However, the amount of energy harvested is very limited and I don't think it's going to be enough to charge you laptop battery
