Pune researchers fabricate a flexible nanogenerator for wearable electronics

Producing wearable electronics that uses a portable nanogenerator which generates electric power when pressure or twist is applied got a shot in the arm, thanks to research carried out by Pune researchers. 
●    The nanogenerator, which was fabricated by them, produced 14 volts when thumb pressure was applied. 
●    The results were published recently in the journal Advanced Materials & Interfaces.
●    To demonstrate the potential of the nanogenerator to power small electronic devices, pressure equivalent to thumb pressure was continuously exerted on the nanogenerator for 20 minutes by using a vibration producing motor. 
●    14 volt that was generated was stored in a capacitor and used for charging a mobile phone.
●    Currently, there is considerable research emphasis to develop flexible or wearable devices. Such devices should be portable, lightweight, shock-resistant, and inexpensive. 
●    And the devices should ideally be powered by harvesting easily available mechanical or vibration energy, making battery or related wiring redundant.
