Making a Low-Cost Touch Sensing Using Electric Field Tomography “Electrick”

Because electric touch sensing technology is expensive to develop and produce, you’re unlikely to find examples of it on objects much larger than a computer screen. You could theoretically make an entire wall in your apartment touch-sensitive using the same tech used in smartphones, but it would cost a fortune.

You’re also unlikely to find such technology incorporated into anything with a strange shape: smartphones are relatively easy to make touch-responsive, since they are flat. But try adding a touch sensor to the end of a hammer or corkscrew, and you’ll soon run into trouble.

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.
