人造皮肤技术的下一步发展可将其灵感归功于甲壳虫翅膀。研究者试图研制出一种柔性传感器,能像甲壳虫休息时翅膀上互锁的微毛发所触发的皮肤感知触碰一样检测到机械压力。“你可以想象得到,在互锁中会发生一个大的界面接触,这是一个灵敏的传感器的优秀特点。”首尔大学首席研究员卡帕·杨·苏(Kahp Yang Suh)在邮件中写道。因为接触到这么多表面区域,一个依赖于纳米纤维连接的传感器甚至能检测到改变纤维相对位置的极小扰动。
The next step in the development of artificial skin technology owes its inspiration to the Beatles’ wings. The researchers sought to develop a flexible sensor that senses mechanical stress the same as a skin-sensory touch triggered by interlocking hair on the wings of a Beetle resting. “As you can imagine, a large interface occurs in interlocking and this is an excellent feature of a sensitive sensor.” Kahp Yang Suh, chief researcher at Seoul National University, wrote in his email Road. With so many surface areas exposed, a nanofiber-based sensor can detect even small perturbations that change the relative position of the fibers.
