We created physical prototypes and 3D renders to convey the form design (shape, size, materiality, etc).
We decided to create a physical prototype with Low-Temperature Thermoplastics which is mealliable when heated and hardens when it cools. The 3D rendered images communicate how users can form the device to their wrist to ensure a snug fit. We imagine using thermoplastic polyurethane for the external material of the device. The material is similar to a silicone phone case that is long lasting and flexible, but still retains its shape.
