Abstract:
The development of stretchable, mechanically and electrically robust interconnects by printing an elastic, silver-based composite ink onto stretchable fabric. Such interconnects can have conductivity of 3000-4000 S/cm and are durable under cyclic stretching. In serpentine shape, the fabric-based conductor is enhanced in electrical durability. Resistance increases only ˜5 times when cyclically stretched over a thousand times from zero to 30% strain at a rate of 4% strain per second due to the ink permeating the textile structure. The textile fibers are ‘wetted’ with composite ink to form a conductive, stretchable cladding of the silver particles. The e-textile can realize a fully printed, double-sided electronic system of sensor-textile-interconnect integration. The double-sided e-textile can be used for a surface electromyography (sEMG) system to monitor muscles activities, an electroencephalography (EEG) system to record brain waves, and the like.
