Singapore researchers have developed "electronic skin" capable of recreating a sense of touch, an innovation they hope will allow people with prosthetic limbs to detect objects, as well as feel texture, or even temperature and pain.

The device, called Asynchronous Coded Electronic Skin (ACES), is made up of 100 small sensors and is about 1 sq.cm in size.

The researchers at the National University of Singapore said it can process information faster than the human nervous system, is able to recognise 20 to 30 different textures and can read Braille letters with more than 90 percent accuracy.

According to research team leader Benjamin Tee, humans need to slide to feel texture, but in this case the skin, with just a single touch, is able to detect textures of different roughness. AI algorithms let the device learn quickly, he added.

 

A demonstration showed the device could detect that a squishy stress ball was soft, and determine that a solid plastic ball was hard.

Tee said the concept was inspired by a scene from the Star Wars movie trilogy in which the character Luke Skywalker loses his right hand and it is replaced by a robotic one, seemingly able to experience touch sensations again.

The technology is still in the experimental stage, but there has been "tremendous interest", especially from the medical community, Tee added.

Previously, the team developed similar patents such as a transparent skin that can repair itself when torn and a light-emitting material for wearable electronic devices./.VNA
