Shape Changing Surfaces and Structures: Design Tools and Methods for Electroactive Polymers.
2019
Electroactive polymers (EAP) are a promising material for shape changing interfaces, soft robotics and other novel design explorations. However, the uptake of EAP prototyping in design, art and architecture has been slow due to limited commercial availability, challenging high voltage electronics and lack of simple fabrication techniques. This paper introduces DIY tools for building and activating EAP prototypes, together with design methods for making novel shape-changing surfaces and structures, outside of material science labs. We present iterations of our methods and tools, their use and evaluation in participatory workshops and public installations and how they affect the design outcomes. We discuss unique aesthetic and interactive experiences enabled by the organic and subtle movement of semi-transparent EAP membranes. Finally, we summarise the potential of design tools and methods to facilitate increased exploration of interactive EAP prototypes and outline future steps.
