Developed by MSU Associate Professor of Electrical and Computer Engineering Nelson Sepulveda and his team, these devices can generate power as they are bent and folded. The devices are called biocompatible ferroelectret nanogenerators, or FENG for short. Power is generated by the device’s many layers as energy is introduced via other sources, such as the user’s motion. This could potentially lead to the ability to charge a device by simply moving around with FENG technology. Furthermore, there are potential security applications to this new tech. Since FENG material is so sensitive, it can be used as a microphone that would make it practically impossible to trick a voice-recognition system. ...
