Adafruit Product Code: 1324
Conductive hook & loop tape is just like the "Velcro" you've seen on clothes and bags, but is coated with silver to make it fully conductive. Originally this was designed to the manufacture of static-safe clothing, but its great for wearable applications as well. For example an on-off switch or sensor.
Each order ships with three inches of BOTH halves, its easily sewn or cut.
