Scientists have made a step forward in their ability to mimic the sense of touch.
A team from the US and China made an experimental array that can sense pressure in the same range as the human fingertip.
The advance could speed the development of smarter artificial skin capable of “feeling” activity on the surface.
The sensors, which are described in Science magazine, could also help give robots a more adaptive sense of touch.
Using bundles of vertical zinc oxide nanowires, the researchers built arrays consisting of about 8,000 transistors.
