Moving things with a wave of the hand: thanks to Empa technology this dream could soon become real. A sensor made of electroconductive piezo-resistive fibers integrated in a wristband measures wrist movements and converts them into electrical signals, which can be read by a terminal device and interpreted. This can be used to steer drones or other electronic devices without a remote control. A wave to the left: the drone moves to the left. A wave to the right: the drone turns right. Clench your hand into a fist and it lands gently on the table.
Although motion sensors are nothing new, until now movements were primarily recorded using...
