Engineers have created electronic skin that recognizes touch without sensors

A team of engineers from the University of Glasgow (Scotland) has developed an electronic skin that recognizes touch and proximity without sensors.
The skin is based on miniature solar cells – they are responsible for both power and tactility. These cells recognize proximity by the shadow of a moving object. The moment of the lowest light is considered to be the touch.
Typical electronic skin consumes a lot of energy, so it is not practical for use with fully autonomous robots. A new development solves this problem. See how the technology works in practice in the video below.
