(PhysOrg.com) -- Space seems exotic, forbidding, and remote, but imagine trying to survive winter without a heated shelter or warm clothing. Our ancestors developed these technologies because they needed room to grow; without ...
Researchers are studying data from a recent suborbital flight test to better understand lunar regolith, or moon dust, and its potentially damaging effects as NASA prepares to send astronauts back to the lunar surface under ...
The whirling blades on drones flying above Mars may cause tiny electric currents to flow in the Martian atmosphere, according to a NASA study. These currents, if large enough, might cause the air surrounding the craft to ...
A new report on Science Advances developed by Mirco Kaponig and colleagues in physics and nanointegration in Germany, detailed the very basic concept of contact electrification between two metals. In a new experimental method, ...
A stretchable system that can harvest energy from human breathing and motion for use in wearable health-monitoring devices may be possible, according to an international team of researchers, led by Huanyu "Larry" Cheng, Dorothy ...
An innovation turning waste material into stretchable devices may soon provide a new option for creating self-powered biomedical inventions.
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users. The ...
In approximately 600 B.C., the Greek philosopher Thales of Miletos discovered that rubbing certain materials together, such as amber and wool, can cause both to become electrically charged, one positive and one negative. ...
Have you ever walked across a wool carpet in leather-soled shoes on a dry winter day, and then reached out toward a doorknob? ZAP! A stinging spark leaps between your fingers and the metal knob.
Nanoscientists have developed a wearable textile that can convert body movement into useable electricity and even store that energy. The fabric potentially has a wide range of applications from medical monitoring to assisting ...
