A woven panel is provided that utilizes grip yarns in the weft direction in a first area to increase the coefficient of friction of the woven panel. The grip yarns are interlaced with a plurality of non-grip yarns to form a repeating pattern of floats on the woven panel, that when sewn into a garment, provide additional traction and friction for securing the garment to a wearer's body.

A weaving apparatus comprising a shuttleless loom with a weft insertion device. A transfer device and retaining disc are connected to the weft insertion device such that the retaining disc holds the weft fiber in a fixed orientation as it traverses through the shed of the loom. A plurality of sensors which are part of a microcircuit are mounted on the retaining disc for measurement of the weft fiber's position. A signaling circuit is mounted on the shuttleless loom and an electrical connector is connected to the signaling circuit to allow for external monitoring or display of the weft fiber's position. The measurements from the plurality of sensors are communicated through the electrical connector to an external device such that the position and orientation of the weft fiber can be monitored or displayed as the weft insertion device travels through the shuttleless loom.

A wearable, nanoconductor technology for smart electronic applications. A novel nano-scale geometry is achieved for nanoconductor circuits on the order of the size of a single thread or smaller, which are easily integrated with clothing and provide smart applications for wearable electronics. The nano-scale fibers provide improved material characteristics and the fixed geometry and orientation of the nanoconductor structures allow easier interface of nanoconductor electronics integrated with the clothing or with electronics external to the weave of the clothing. Novel electronic circuits based on the size and fixed geometries of the nanoconductor fibers which allow configurable functions that can be employed for different uses through logic circuit configuration or serial programming during wear are disclosed.
