Rotospray (ProtoSpray) – a new touch display, created at the intersection of 3D printing and the coating of electronic technology by scientists at Bristol University (UK).
The video shows how ProtoSpray works when spraying on the cube, hemisphere and a flexible tube in the form of a möbius strip, demonstrating the flexibility of the new process.
These objects combine 3D printed substrate, attached to it electrodes and uniformly distributed layer of electroluminescent ink (EL). According to the researchers, their goal is to give people a new view on displays as plastics or paints.
When an electric current painted surface is partially light up or respond to touch-simple touches that can be used, for example, for opening doors or creating illuminated signs for Museum tours.
