For a long time, paint has pretty much had one simple purpose: changing the color of objects. But with the future comes a whole lot of new uses for a whole lot of old objects. For example, we now have paint that absorbs room odors. And the London-based Bare Conductive Ltd. has created a paint that conducts electricity.
The non-toxic paint is called Bare Paint and it dries at room temperature. Created in part by students at the Royal College of Art, the paint offers a number of usages, from the artistic to the practical. From having a working light switch drawn on paper to a sound-producing billboards, Bare Pain truly electrifies painting.
It’s got a surface resistivity of about 55 ohms/square at 50 microns layer thickness. Though water-based, the paint isn’t waterproof and can be easily painted over with waterproof paint or varnish. This is helpful, since it only comes in black.
"We generally split applications into two simple classifications, signaling and powering," said the inventors. "Signaling could include using the Paint as a potentiometer while interfacing with a micro-controller, as a conduit in a larger circuit or as a capacitive sensor. Powering a device would include lighting LED's or driving small speakers. The most interesting stuff happens when you combine these properties into something new."
