Electric Paint Puff Sensor

Experimentations with Electric Paint and puff ink

Earlier this year the team at EJ Tech blew us away with their flexible MIDI controller, and are now experimenting with Electric Paint and puff ink! They tried mixing the two materials (puff ink is normally used for printing textured surfaces onto t-shirts). This combination allowed for a puffy, conductive material that can be turned into a sensor once connected to a microcontroller such as the Touch Board.

Remember that mixing Electric Paint with another material will decrease its conductivity. Check this tutorial to see how adding water changes the performance.

Materials To begin you will need:

1 x Electric Paint 50ml Jar
Puff ink for screenprinting
Hot Gun / Hairdryer

hairdryer and making materials on white background

Step 1

Mix the Puff ink with Electric Paint in a 1:1 ratio

Step 2

Apply the mixture onto your chosen surface generously – it can also be screen printed.

Step 3

Heat with the hot gun for about 3 minutes. Be carefully not to keep the gun to close to your surface or you will burn it! The surface of the paint with start to expand!


Step 4

Check out the video to see the process in action!
