5.3K views | How do touchscreens respond to your finger? Most modern touch screens use capacitive sensing. Your finger, being conductive, disturbs the tiny electric fields on the screen. Sensors detect this change and translate it into location data. Engineers made these so precise that multitouch gestures—pinching, swiping, zooming—are now seamless. Its electrical fields, invisible but responsive, turning glass into an interface we can't live without. | Electricalgram | Facebook

Researchers have designed a soft tactile sensor that can detect where it’s being touched, while differentiating between different kinds of touch, with an accuracy comparable to that of human skin. Learn more from Science Robotics: https://fcld.ly/fxfrkgm | Science
