Measuring Pressure With The Help Of Static Electricity
On a dry winter day, shuffling across a carpeted floor often can end in a painful shock thanks to static electricity. A team of scientists would like to exploit the phenomenon behind that annoying zap to build useful devices. By harnessing the electron exchange created when certain materials rub together, the researchers developed a simple and inexpensive pressure sensor that doesn’t need an external power source (ACS Nano . . .
