Engineers turned drawings on the wall into “buttons” for controlling devices

Engineers from the Massachusetts Institute of Technology (MIT) turned drawings on the wall into “buttons”

device management. To create the graffiti, they used special airbrush ink.

The SprayableTech system allows you to create interactive graphics of any size on any surface. Drawings can be used to, for example, turn lights or a TV on and off.

First, an interactive drawing is created in3D editor. The system then generates stencils for application to the surface. After this, various inks are applied - conductive copper, dielectrics, phosphorus, etc. Finally, a microcontroller is attached.

The bulk of the work when creating suchcontrols are performed when designing stencils. After all, you can’t just put paint on the wall and hope that it can do something. To facilitate the application of their technology, engineers develop off-the-shelf modular stencils.
