韩国研究人员研制出一种新型电子感应器。这种感应器由两层薄膜叠加在一起形成,总厚度在1毫米左右。每层薄膜的表面都像“刷子”一样布满细小的纤维,每根纤维直径约100纳米,长约1微米,其表面覆盖着发挥导电作用的金属。把这两层薄膜有“刷毛”的一面相向叠加,其纤维之间的接触就会形成导电通路。如果这种感应器受到外力,大量细 South Korean researchers developed a new type of electronic sensor. The sensor consists of two layers of film stacked together to form a total thickness of about 1 mm. The surface of each film is covered with tiny fibers like the “brush”, each with a diameter of about 100 nanometers and a length of about 1 micrometer. The surface of the film is covered with a metal that acts as an electrical conductor. The two layers of film have “bristles” side of the stack, the contact between the fibers will form a conductive path. If this sensor by external force, a lot of fine
