Flocking Masks

This spring I’m making a series of custom masks for my four closest friends that will respond to their facial gestures by activating features on the outside surface. This project is called the “Flocking Masks” and will hopefully yield some fun summer shenanigans later this year! Any hoo… the way in which I’m making these masks reactive involves a somewhat simple capacitance circuit that exploits the properties of the materials forming the circuit. Connected to my circuit are several copper pads; one to act as ground, the other two for sensing. The charge of your body effects the charge on the pads, so the amount of skin contacting the pad relates to a degree of capacitance, and can act as a granular trigger! While this works nicely in a bread board with some red LEDs, I need to mount these pads inside of a mask and test the viability of…
