Please visit the campaign page to see more photos of the stickers and to see how they can be used.
Here, I will write a bit about the background story, tech details, and manufacturing processes that went into making them.
Circuit stickers are peel-and-stick electronics for crafting circuits. In a nutshell, they are circuits on a flexible polyimide substrate with anisotropic tape (or “Z-tape” — so named because electricity only flows vertically through the tape, and not laterally) laminated on the back.
The use of Z-tape allows one to assemble circuits without the need for high-temperature processing (e.g. soldering or reflow), thereby enabling compatibility with heat-sensitive and/or pliable material substrates, such as paper, fabric, plastic, and so forth.
This enables electronics to be integrated in a range of non-traditional material systems with great aesthetic effect, as exemplified by the addition of circuit stickers to fabric and paper.
