摘要
柔性电路能解决传统金属导体受到机械应力时易失效的问题,并使柔性机器人的变形与运动不再受到传统金属导体的束缚。本工作把材料结构设计与电路设计相结合,利用柔性材料在力的作用下产生的弹性形变形成不同信息通道的机理,设计出一种新型柔性电路。该电路是柔性材料和导电材料所构成的复合物,初始状态下,该复合物内部内没有任何信息通路,可通过手动方式使其变形并搭接成相应的信息通路,形成“与”“或”“异或”等多种逻辑门。该逻辑门的输入为力,输出用LED灯的“亮、灭”状态来显示。有限元仿真和实验表明,该柔性电路能够稳健地实现既定的逻辑功能。在未来,可将这种柔性电路嵌入机器人、传感器或驱动器中,有望使得这些装置产生与环境相适应的决策智能。
The flexible circuits can solve the problem that traditional metal conductors are easy to fail when subjected to mechanical stress,which makes the deformation and movement of the flexible robot no longer constrained by the traditional metal conductor.In this work,a new type of flexible circuit is designed by combining material structure design with circuit design,using the mechanism that flexible materials form different information channels under the action of force.The circuit is a complex mixture of flexibe materials and conductive materials.In the initial state,there is no information path inside the mixture,which can be deformed and bonded into the corresponding information path by manual means to form a variety of logic gates such as‘AND’‘OR’‘XOR’and so on.The input of the logic gate is force,and the output is displayed with the‘on and off’state of an LED light.Finite element simulations and experiments show that flexible circuits can realize the desired logic function robustly.In the future,such flexible circuits could be embedded in robots,sensors or drivers,which is expected to enable these devices to generate decision-making intelligence that is adapted to the environment.
