使用容易获得的材料和可重复的技术手段,单向变体(uniMorph)利用简单的单驱动原理,这种原理可以在双金属结合铜的热电特性和超高分子量聚乙烯以及聚酰亚胺的不同热膨胀率(UHMW-PE)中发现。单向变体(uniMorph)使可塑性薄片进行主动和被动的形状变化。

无源驱动可以利用获得的热量,就像一个灯泡的热量,来创建简单的形状变换。更加复杂的主动形状变化可以通过在一个可调节电路系统中设计一个电阻加热模型。这一电路系统也可以允许额外的电子器件例如传感器、LED、甚至是微型控制器。

所有应用的例子均在Arduino中进行编程并且在定制的Arduino拓展板上运行。在某些案例里,灵活的电路设计可以使Arduino微型控制器(ATMega328P)直接焊接在上面。

Created by Felix Heibeck, Basheer Tome and Clark Della Silva with supervision from Hiroshi Ishii at the MIT’s Tangible Media Group, uniMorph is an enabling technology for rapid digital fabrication of customized thin-film shape-changing interfaces.

Working with easily available materials and reproducible techniques, uniMorph project leverages the simple unimorph actuation principle that can be found in bi-metals and combines it with the thermoelectric characteristics of copper and the vastly different thermal expansion rate of ultra-high molecular weight polyethylene (UHMW PE) and Kapton. uniMorph enables passive and active shape-actuation of thin flexible sheets and circuits.

Passive actuation can leverage access heat, like the heat from a lightbulb, to create simple shape transformations. More complex and active shape-actuation can be achieved by designing resistive heating patterns into a flexible circuit. The use of flexible circuits also allows for additional electronics such as sensors, LEDs, and even microcontrollers.

The examples of application have all been programmed in Arduino and run on custom Arduino compatible boards. In some cases, the flexible circuits were designed so the Arduino microchips (ATMega328P) could be soldered right on top of them.

The shape-changing actuation is enabled by a temperature driven mechanism and reduces the complexity of fabrication for thin shape-changing interfaces. UniMorph composites can be actuated by either environmental temperature changes or active heating of embedded structures and can actuate in different shape-changing primitives. Different sensing techniques that leverage the existing copper structures can be seamlessly embedded into the uniMorph composite.
