现实版画皮:新型人造皮肤具有真实感知体验

[复制链接]

A new form of artificial skin, threaded with a network of artificial sensors, could recreate the sense of touch for people wearing prosthetic limbs, researchers revealed on Tuesday.

据美国《时代周刊》报道,研究人员12月9日透露,一种植入传感器网络的新型人造皮肤能让戴假肢的人重获感知体验。

Researchers in Korea and the U.S.have developed a new form of ultra-thin sensors that can pick up sensations of heat, pressure and moisture, MIT Technology Review reports. The sensors are malleable enough to be woven into a thin layer of polymer. The breakthrough, researchers say, came when they packed the skin with enough sensors, up to 400 per square millimeter, to recreate the sensations of human touch.

据美国《麻省理工科技评论》杂志(MIT Technology Review)报道,韩国和美国的研究人员研发出了一种超薄型传感器,能感知外界的温度、压力和湿度。这种传感器有足够的柔韧性,能被植入一层超薄的高分子聚合物。研究者表示,这种高分子聚合物材质的突破性进展在于,其每平方毫米的传感器数量高达400个,足够让假肢获得真实的感知体验。

If you have these sensors at high resolution across the finger, you can give the same tactile touch that the normal hand would convey to the brain,” said contributing researcher Roozbeh Ghaffari.

该项目研究人员鲁兹贝·加法里(Roozbeh Ghaffari)说:“如果手指假肢能够配置拥有如此高分辨率的传感器皮肤,大脑就可以接收到与正常手指几乎相同的触觉反馈。”
