Breathable, wearable electronics on skin for long-term health monitoring

ScienceDaily.com: Nanotechnology News - 17 июля, 2017 - 18:05
A hypoallergenic electronic sensor can be worn on the skin continuously for a week without discomfort, and is so light and thin that users forget they even have it on, say scientists. The elastic electrode constructed of breathable nanoscale meshes holds promise for the development of noninvasive e-skin devices that can monitor a person's health continuously over a long period.

Researchers develop new transistor concept

Nanowerk.com - 14 июля, 2017 - 21:09
The researchers use metal nanoparticles which are so small that they no longer show their metallic character under current flow but exhibit an energy gap caused by the Coulomb repulsion of the electrons among one another. Via a controlling voltage, this gap can be shifted energetically and the current can thus be switched on and off as desired.
