A Nanowerk Spotlight

Nanopiezotronics describes the coupled piezoelectric and semiconducting property of nanowires and nanobelts for designing and fabricating novel electronic devices such as nanotransistors and nanodiodes.

Biomechanical energy is one of the main energy components in biological systems. Developing an effective technique that can convert biomechanical energy into electricity is important for the future of in vivo implantable biosensors and other nanomedical devices.

Longevity gene may also boost memory

The same molecular mechanism that increases life span through calorie restriction may help boost memory and brainpower.
