摘　　要：As future soft robotic devices necessitate a level of complexity surpassing current standards,a new design approach is needed that integrates multiple systems necessary to synchronize the motions of soft actuators and the response of signals,thereby enhancing the intelligence of flexible devices.Herein,we propose a liquid crystal elastomer unit cell-based platform that organizes the cells in a group to create expandable functions.One unit cell behaves like a flexible module that can expand biaxially into a specific,stable,and controllable pattern.Collaborating the unit cells in different manners results in an adaptable soft grasper,a half-adder for information processing,and a tunable phononic bandgap.This implies a high level of reconfigurability and scalability in both structures and functions by elegantly reassembling the unit cells.This design strategy has the potential to integrate multiple functions that traditional soft actuators cannot accommodate,providing a platform for developing intelligent soft robotics.未来软体机器人设备的复杂性远超当前标准,因而需要建立新的设计方法.该方法需整合多个系统,以同步软执行器的运动和信号响应,从而增强柔性设备的智能性.本文提出了一个基于液晶弹性体(LCE)单元的平台,该平台将单元整合成组,以创建可扩展的功能.每个单元的行为都是一个柔性驱动模块,可以在特定、稳定和可控的模式下进行双轴膨胀.通过以不同的方式组织LCE单元,分别实现了自适应性的软夹持器、信息处理的半加器和可调的声子带隙.这表明通过精巧地重新组装这些单元,可以在结构和功能上具备高度的可重构性和可扩展性.这种设计策略有望整合传统软执行器无法具备的多种功能,为开发智能软机器人提供平台.
