Newnagy has made an important breakthrough in nanogenerator technology.  By improving technics and process, our R&D team invented a type of nanogenerator that is of low cost and easy to fabricate.  One generator of such type, made of thin film material and with a dimension of 3cm by 3cm, can turn on 300 LED lights at once.  It produces voltage as high as several kilovolts and current as much as 6.75mA.  These nanogenerators can be stacked in multiple layers to generate high power to drive many electronic devices.  It is an important invention in the field of power source for micro-nano devices.
