摘要

Textile-based electronic techniques that can in real-time and noncontact detect the respiration rate and respiratory arrest are highly desired for human health monitoring. Yarn-shaped humidity sensor is fabricated based on a sensitive fiber with relatively high specific surface area and abnormal cross-section. The response and recovery time of the yarn-shaped humidity sensor is only 3.5 and 4 s, respectively, with little hysteresis, because of the hydrophobic property of these functional fibers and the grooves on the surface of the fibers, which is much faster than those of the commercial polyimide materials. Moreover, a battery-free LC wireless testing system combined with the yarn-shaped sensor is fabricated, which is further successfully imbedded into the intelligent mask to detect human breath. Based on the detection of LC wireless testing system, the frequency of 50.25 MHz under the exhaled condition shifts to 50.86 MHz under the inhaled situation of humidity sensor. In essence, the functional yarns with proper structure, would be an excellent candidature to the yarn-shaped humidity sensor, in which there are good performance and wide application possibilities, eventually offering a facile method for the wireless detection of human physiological signals in the field of electronic fabrics.
