Capacitive Touch Sensor & Interface
The Knit Capacitive Touch Sensor (CTS) is a gesture sensitive functional textile touchpad interface for physical devices developed at the Center for Functional Fabrics (CFF) at Drexel University. The CTS is produced as a single piece of fabric requiring only two electrodes to connect it to a microcontroller. The CTS offers a solution for a flexible touch interface with consistent location detection, responsiveness, comfort and unobtrusiveness. It is robust and can sustain daily wear and tear. It is also washable. CFF and Apex Mills (a warp knitting manufacturing facility with over 100 machines producing 20 million yards of fabrics per year), have teamed up to develop the CTS beyond TRL 4, given its tremendous potential for a variety of markets, including developing products for commercial and military use here in the United States. Both Apex Mills and CFF are aligned with AFFOA’s mission to further the development of innovative functional fabrics products, and US manufacturing.
