In this class, we made a soft switch. It contains three layers: one conductive layer, one layer of velostat, and one thick layer of cloth in between to create the space.

It is used for the protection of items or devices that are susceptible to
damage from electrostatic discharge.
And we noticed that the velostat is super sensitive, as can be seen from the serial here
