Stress Buster gadget converts your tension into energy

A new “piezoelectric” design that could capture the imagination of stressed techies everywhere caught the eye of Tech Boutique the other day.

It may sound ultra-technical, but the idea is a simple one, based on the principle that energy is never created or destroyed – only transformed from one state to another.

Indian freelance designer Saravanan Nagasundaram recently published his Stress Buster designs based on this principle for a punching bag, kicking column and squeeze ball that house lamps, which are powered by energy stored in a built-in rechargeable battery every time they are used.

Each gadget has been designed with a piezoelectric layer that has the ability to generate an electrical field or electric potential in response to applied mechanical strain. So, the more you kick, punch or squeeze them, the more energy you can store. They can all be used as small green power generators, as each has been designed with power outlet sockets.

All in all, an ingenious concept that could consign the humble rubber stress ball to the bin if it finds a route to market.
