“…Self-folding robotics is a domain dedicated to developing autonomously self-assembling robots, often inspired by origami folding patterns [13,26,27]. In contrast with other electromechanical methods for self-assembly, self-folding robotics focuses on shape actuation material actuation mechanisms instead of motors or other external devices [13].…”

“…While some use external actuation energy like baking [26] or local light absorption [23], some researchers leverage the advantages of joule heating with thin copper traces for local heat actuation [4]. Previous work on reversible material shape actuation for sheets using nitinol [13] and electroactive polymers [27] is impossible to reproduce without expensive equipment. Piezoelectric actuators can be found in the same thin-sheet form factor [24], but have drawbacks that make them impractical for shape-changing interfaces.…”

“…Thus far, design of these components has been separated from overall mechanism design. Shapechanging flexible circuits have been shown in robotic works [4,27], however the presented composites are either nonreversible one-time actuation [4] or impossible to reproduce with common lab devices [27]. By combining the thermoelectric characteristics of copper with the high thermal expansion rate of ultra-high molecular weight polyethylene (UHMW PE), we are able to actuate flexible circuit composites directly.…”

Figure 1. uniMorph contributes a rapid digital fabrication approach enabling designers to print custom shape-changing composites. With its multitude of capabilities for transformation and integration of electronics it facilitates a wide range of applications in shape-changing interfaces. ABSTRACTResearchers have been investigating shape-changing interfaces, however technologies for thin, reversible shape change remain complicated to fabricate. uniMorph is an enabling technology for rapid digital fabrication of customized thinfilm shape-changing interfaces. By combining the thermoelectric characteristics of copper with the high thermal expansion rate of ultra-high molecular weight polyethylene, we are able to actuate the shape of flexible circuit composites directly. The shape-changing actuation is enabled by a temperature driven mechanism and reduces the complexity of fabrication for thin shape-changing interfaces. In this paper we describe how to design and fabricate thin uniMorph composites. We present composites that are actuated by either environmental temperature changes or active heating of embedded structures and provide a systematic overview of shapechanging primitives. Finally, we present different sensing techniques that leverage the existing copper structures or can be seamlessly embedded into the uniMorph composite. To demonstrate the wide applicability of uniMorph, we present several applications in ubiquitous and mobile computing.

“…To improve the performance of these actuators overcoming problems of fragility, multilayered actuators were proposed (Hara et al, 2006;Kaneto et al, 2008;Kaneto et al, 2009), in which several thin conducting polymer films and an electrolyte (ionic liquid-soaked paper) are used to develop a compact and scalable longitudinal actuator with a high work output (Ikushima et al, 2009). Also folded films with Origami shapes provide good linear movements (Okuzaki, 2008).…”
