Knit jersey conductive fabric - Product 1364 - Details

Post by n_pyman »

I'm looking for a datasheet/ linearity property details of the knit jersey conductive fabric (https://www.adafruit.com/products/1364) - Change of resistance vs strain/load applied. Any help or any other reference to this particular aspect is much appreciated. Thanks.

No details aside from the description about makeup, resistance and stretch direction.
This knit jersey conductive fabric is 63% cotton, 35% silver yarn and 2% spandex. Use small pieces for soft switches, plush keypads, capacitive touch sensors, and other textile interfaces. It's very soft and matte, perfect for ironing onto wearables with double sided interfacing. This conductive fabric has different resistance in each direction: 46 ohms per foot across the rows (stretchier direction) and 460 ohms per foot across the columns (less stretchy direction). This is because a knit is comprised of a single strand of fiber that travels back and forth across the fabric.
However, there is a datasheet for the Silver 20cm fabric square that might be helpful.

Thank you. Looking for additional information on linearity characteristics on this one. Someone would have carried out some initial tests (??) on these characteristics and thought I can refer to that one.
