Electronic spray turns any surface into a touchscreen

ProtoSpray is a new type of touchscreen display created at the intersection of 3D printing methods and sprayed electronic technology by scientists at the University of Bristol (UK).

The video shows how ProtoSpray works when sprayed onto a cube, hemisphere, and flexible Mobius strip, demonstrating the flexibility of the new process.

These objects combine a 3D printed substrate, attached electrodes, and an evenly distributed layer of electroluminescent (EL) ink. Their goal, the researchers said, is to give people a new understanding of displays as plastics or paints.

When an electric current is applied, painted surfaces partially light up or react to simple sensory touches, which can be used, for example, to open doors or create luminous signs for museum tours.
