Remotely Controlling Electronic Devices with Hand Gestures
From: ECN Magazine - 07/11/2017

Empa researchers headed by Frank Clemens from the Laboratory for
High-Performance Ceramics have devised a sensor made of piezo-resistive
fibers and incorporated it into a wristband that registers the hand's
movements. The piezo-resistive fiber is electroconductive, recognizes a
change in shape and converts it into an electrical signal, which can then be
read by a terminal device and interpreted accordingly. This means that robots
can be moved with a simple point of the finger, for instance.
