That could change soon, as researchers at Carnegie Mellon University say they’ve come up with a way to make many kinds of devices responsive to touch just by spraying them with conductive paint, adding electrodes, and computing where you press on them. Researchers at Carnegie Mellon University have found a way to make objects responsive to touch using conductive paint and brushes . The system , called Elektrick , can be applied to most surfaces , including metal , silicone and even Jell - O , to make non - interactive objects touch sensitive . The team sprayed the objects with the conductive paint , placed electrodes and connected them to a sensor board and laptop , which was then able to detect touch . The method could be used to make touch objects more sensitive , as the devices were 99 % accurate at determining touch and accurate to within one second of touch - tracking distance .
