Pressure-Sensitive Conductive Sheet

Pressure-Sensitive Conductive Sheet (Velostat/Linqstat)

If you’re thinking of creating sensors and wearable projects, this conductive material, also known as ‘Velostat’ or ‘Linqstat’, is an excellent addition to your kit. Shaped like a sheet, this material is pressure-sensitive. In fact, when compressed, its resistance decreases, making it ideal for creating flexible sensors. Furthermore, it is much cheaper than the standard pressure or bend sensors available on the market.

Each pack of this product includes a 28cm x 28cm (11″x11″) sheet with a thickness of 0.1mm (4 mil). To make it easier to post, the sheet may be folded into four sections. But don’t worry – if you want to remove any creases, simply lay it flat on a flat surface and place a heavy book on top to flatten it.
