Singapore researchers say they have developed a form of electronic skin that can create a sense of touch. They hope their invention will give people with prosthetic hands (假肢手) the ability to identify different objects.
The skin device measures 1 square centimeter. The system contains 100 small sensors that attempt to recreate things like texture (质地), temperature and even pain. The researchers call the device Asynchronous Coded Electronic Skin, or ACES, which can process information faster than humans' nervous system. Machine learning methods trained the device to recognize 20 to 30 different textures. It can even correctly read Braille letters most of the time, the researchers say.
The system does not require the users' movement to work. 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.
A demonstration showed that the device could identify the difference between a soft ball and a solid plastic one. "When you lose your sense of touch, you essentially become numb and prosthetic users face that problem, " said Benjamin Tee, leader of the research team. "So by recreating an artificial version of the skin, for their prosthetic devices, they can hold a hand and feel the warmth and feel that it is soft."
Tee said his idea for the device came from the movie Star Wars, when character Luke Skywalker loses his right hand and it is replaced with a robotic one. In the film, the new hand is able to experience touch sensations just like the real one.
The artificial skin technology is still going through experiments and development. But Tee said there had already been a lot of interest in the system, especially from the medical community. Tee said similar inventions that his team has developed include see-through skin that can repair itself when torn and a material for wearable electronic devices that gives off light.

Barcelona is a city of contradictions: old and new combined, beautiful and industrial, traditional and modern. Bordered by France to the north and the Mediterranean Sea to the east, Barcelona is one of the most “European” of Spanish cities. Stroll Las Rambles, one of the city's most famous and busy avenue. Students taking a gap year in Barcelona will find it to be a very cosmopolitan(世界性的) city that combines the latest trends with the most typical Spanish traditions. Barcelona offers museums, cinemas, restaurants, the beach, the mountains, and people from all over the world. Although local people speak both Spanish and Catalan, the mixture of local residents and international visitors makes it an easy city to understand and makes yourself understood. Barcelona exposes students to several cultures, languages, and world views; but then again, what else could be expected from the complex city of Barcelona? |
