A Rain Powered Electric Umbrella

LightDrops looks like an ordinary umbrella but don’t let that fool ya. There’s more than meets the eye here. As water pours over the surface, potential energy from raindrops slamming onto the conductive membrane called polyvinylidene fluoride (PDVF) transforms into electrical energy powering embedded LEDs sending your umbrella ablaze with light. The heavier the rain, the brighter the light to help you see your way.
This working principle behind this umbrella is Piezoelectric Effect i.e. Certain materials produce electric charge when mechanical stress is applied on them.
Totally an ingenious idea to use the piezoelectric effect to light the way while raining.
