Abstract: A warp-knitted capacitive touch sensor system includes conductive and non-conductive yarns using interlooped stitches that are interlaced, intertwined, and/or spliced into a single conductive pathway having only two connection points to the electronic interface device, across a desired width or length of the textile material.

Abstract: A garment includes a supercapacitor and/or heated fabrics including a first conductive yarn knitted to as to form a current collector and a second conductive yarn knitted to as to form an electrode that is in electrical contact with the current collector. The conductive yarns are knitted into a predetermined supercapacitor design having respective electrodes that are not in electrical contact with each other. An electrolyte saturates at least the electrode material either before or after knitting, and an ionically permeable electronic separator allows the electrodes to be in close proximity to each other without being in electrical contact with each other. A heating element may also be formed by knitting at least one of the first and second conductive yarns into a linear resistor or by knitting an insulated conductive yarn into a sheet of fabric. Such a heating element is connected to the supercapacitor via a switch.

Abstract: A planar (two-dimensional, XY location) touch sensor may include a knitted structure and supplementary method of sensing detects human touch on a fabric surface. This sensor may be fully knitted and detect the continuous planar location and contact force of human touch along the surface of the structure. The fabric may conform to any arbitrary surface and may be a rectangle for touch pad applications. This sensor may be used for applications that include robotics and human-machine interaction, smart garments and wearables, as well as medical textiles and flexible embedded sensors. This touch sensor may require as few as only two electrode connections from the fabric to sense both planar touch and pressure, which allows it to work in areas with limited space that allow for limited complexity for wiring.

Abstract: A wearable power harvesting system includes a knitted fabric rectenna including an antenna adapted to receive radio-frequency energy within a desired frequency band and a rectifier circuit that converts received radio-frequency energy into a DC current and voltage. A knitted fabric load/storage unit stores DC power from the rectifier circuit. The power harvesting system is adapted to harvest the radio-frequency energy within the desired frequency band, which may include WLAN frequencies such as the standard 2.4 GHz and 5 GHz WLAN standard frequencies.
