科學家研製出可伸縮觸感材料人造皮膚
Researchers Create Artificial Skin With Sense of Touch
Artificial robotic hands are getting increasingly better at emulating human hands and the most advanced can even be controlled by thoughts.
人工機械手臂在模仿人手方面正越發完美而且最為先進的機械手甚至可藉由思想進行控制。
But people who wear bionic hands must rely on their sight to know what they are touching or grasping.
但穿戴仿生手臂的使用者必須依靠自身視覺才能獲悉碰觸或抓握的感覺。
Now, though, researchers in South Korea and the U.S. saythey have created a stretchable artificial skin that can register heat, pressure and moisture.
而現在韓國和美國的一組研究人員表示他們已經研製出一種可感知熱力、壓力及溼度的伸縮人造皮膚。
This polymer-based elastic material is not designed to replace damaged human skin, such as in burn victims,but rather to provide high-resolution sensory capabilities for prosthetic limbs or for the limbs of humanoid robots.
這種聚合物為材料製造出的彈性材料不但可以作為諸如燒傷患者等的人類受損皮膚替代品,而且能夠為假肢或人形機器人提供高解析度的感官功能。
Team leader Kim Dae-Hyeong, a professor at the Seoul National University School of Chemical and Biological Engineering,says its sensors are an exact copy of human skin.
該組團隊的領導人，首爾國立大學化學與生物工程學院金大恆教授表示這種傳感器精確複製了人類皮膚。
The skin can feel pressure, temperature, strain, humidity.Also it is soft, just like human skin, and embedded with heating elements that can make itself warm.
這種皮膚能感受到壓力,溫度,壓力及溼度。同樣它也很軟,就像人類的皮膚,而嵌入式的加熱元件可以使自身產生熱量。
Kim says the artificial skin is made of a combination of rubber, polyamideand silicon with sensor density of up to 400 per square millimeter.
金表示這種人造皮膚是由橡膠、聚醯胺和矽製造而成，而傳感器濃度達到每平方毫米400。
An artificial hand wrapped in the new skin could distinguish between dry and moist objects and measure the pressure of the grasp.
新皮膚包裹下的人工手臂能夠區分乾燥和潮溼材質並且對壓力進行測量。
But Kim says what it still can not do is send those signals to a human brain. That, he says, is the scientists』ultimate goal.
但金表示它仍然不能將這些信號發送給大腦。他稱這是科學家們的終極目標。
I hope a robotic limb with this synthetic skin can be used by disabled people.For industrial uses, it can be applied to various types of robots, like a humanoid robot.
我希望機器人義肢與這種合成皮膚可以為供殘疾人帶來便利。而在工業用途中,它可以應用到人形機器人等各類型的機器人。
Scientists say with this sensitive skin, robots may someday be able to type on keyboards and even change a baby’s wet diaper.
科學家們表示憑藉這種感知肌膚機器人可能在未來能夠從事打字工作,甚至替嬰兒換尿布。
