智能形状变化材料可以适应不同的用途，这已经被用于HCI中的动态启示和按需触觉反馈。然而，这些材料的适用性往往受到其复杂制造和编程局部和可单独寻址的响应的挑战的阻碍。在这项工作中，我们提出了一个工具包，用于设计和制造可编程变形对象使用现成的环氧树脂。我们的方法涉及改变交联剂与环氧树脂的比例，以控制变形温度从40 ℃到90 ℃，跨越形状记忆器件的不同区域或跨越器件。功能组件（例如，导电织物、磁性颗粒）也与环氧树脂结合用于感测和主动重新配置。一个工具箱的制造方法和一个原始的设计库，以支持设计构思和可编程变形。最后，我们展示了应用程序的例子，包括变形玩具，形状变化的输入设备，和一个积极的窗口快门。
Smart shape-changing materials can be adapted to different usages, which have been leveraged for dynamic affordances and on-demand haptic feedback in HCI. However, the applicability of these materials is often bottlenecked by their complex fabrication and the challenge of programming localized and individually addressable responses. In this work, we propose a toolkit for designing and fabricating programmable morphing objects using off-the-shelf epoxies. Our method involves varying the crosslinker to epoxy resin ratio to control morphing temperatures from 40 ℃ to 90 ℃, either across different regions of a shape memory device or across devices. Functional components (e.g., conductive fabric, magnetic particles) are also incorporated with the epoxy for sensing and active reconfiguration. A toolbox of fabrication methods and a primitive design library are introduced to support design ideation and programmable morphing. Finally, we demonstrate application examples, including morphing toys, a shape-changing input device, and an active window shutter.
