A research team from the University of Bristol has designed a touchscreen that can be sprayed to any shape via a combination of sprayable electronics and 3D printing.
The technique, called ProtoSpray, allows for displays to be created on surfaces in a variety of shapes and was designed in collaboration with the MIT media lab to develop interactive objects.
Ollie Hanton, PHD student and lead author of the research, University of Bristol said: “We have liberated displays from their 2D rectangular casings by developing a process so people can build interactive objects of any shape. The process is very accessible: it allows end-users to create objects with conductive plastic and electroluminescent paint even if they don’t have expertise in these materials.”
The development marks a breakthrough in attempts to create a machine that can 3D print and spray automatically onto 3D printed objects.
Hanton added: “3D printers have enabled personal fabrication of objects but our work takes this even further to where we print not only plastic but also other materials that are essential for creating displays. Using 3D printing of plastics and spraying of materials that light up when electricity is applied, we can support makers to produce objects of all shapes that can display information and detect touch.
“Our vision is to make screen/display a fundamental expressive medium in the same way people currently use ink, paint, or clay.”
