"generates 2.34 watts per square meter of electricity... hand tapping on 3cm by 4cm piece of fabric continuously light up 100 LEDs, or charge capacitors... continuous stable electrical output... harness vibration energy... potentially extend lifetime of a battery or even to build self-powered systems. To our knowledge, this is the first hybrid perovskite-based energy device that is stable, stretchable, breathable, waterproof, and at the same time capable of delivering outstanding electrical output performance"
