Concealed intelligent switches have significant potential for use in security and encryption applications. Recently, several four-dimensional (4D) printed intelligent devices have been designed and fabricated using 3D printing technologies and intelligent materials. These devices have demonstrated stupendous capabilities in smart switches and actuators. In this study, a concealable smart switch that combines a double spiral structure and smart materials is proposed. To achieve the desired performances, the fixity ratio is optimized to values more than 88% by comparing selected structures printed with common shape-memory materials. Furthermore, applications for non-contact circumstances without any control electric circuits (for example, hidden water valves) are also proposed. Results demonstrate that the outputs of the intelligent switches are related to their different input conditions, and the implementation rules can be further used as black box rules for security and encryption applications. Thus, intelligent devices manufactured using 4D printed shape-memory polymers can be applied in various fields such as in intelligent actuators and soft robots.

基于4D打印形状记忆聚合物的隐藏式智能开关

隐藏式智能开关在安全和加密应用中具有巨大的应用潜力。最近,已经使用 3D 打印技术和智能材料设计和制造了几种四维 (4D) 打印智能设备。这些设备在智能开关和执行器中展示了惊人的功能。在这项研究中,提出了一种结合双螺旋结构和智能材料的隐藏式智能开关。为了达到预期的性能,通过比较使用普通形状记忆材料打印的选定结构,将固定率优化到超过 88% 的值。此外,还提出了用于没有任何控制电路的非接触环境(例如隐藏式水阀)的应用。结果表明,智能交换机的输出与其不同的输入条件有关,其实现规则可进一步用作安全和加密应用的黑盒规则。因此,使用 4D 打印形状记忆聚合物制造的智能设备可以应用于智能执行器和软机器人等各个领域。
