Electrick Spray-on Stick-on or 3D Print Touchpad Technology

Spray on or stick on your conductive layers with a small attached electrodes to measure current, and voila! Just touch! You and even use this technology to make 3D printed objects that are touch sensitive. This is not exactly as precise as what we see on our traditional touchscreens nowadays, but I can see this tech going a long ways in a very short time. This comes from the Future Interfaces Group at Carnegie Mellon University.

We introduce Electrick, a low-cost and versatile sensing technique that enables touch input on a wide variety of objects and surfaces, whether small or large, flat or irregular. This is achieved by using electric field tomography in concert with an electrically conductive material, which can be easily and cheaply added to objects and surfaces through a variety of fabrication methods such as painting, 3D printing, injection molding etc.
