Wearable sensing textiles with continuous
temperature
monitoring,
tactile feedback, and motion perception are highly desirable for personal
safeguarding in extreme environments, such as fire scenes and extreme
sports. However, it remains challenging for current wearable sensors
to maintain reliable performance and provide point-of-care monitoring
in harsh environments, such as high- and low-temperature or high-humidity
conditions. Herein, a robust temperature and pressure sensing textile
(TPST) with a hierarchical triple-weaving structure is developed using
industrial weaving technology. The well-engineered interlacing configuration
of the polyimide binding yarns in the triple-weaving structure tightly
solidifies the carbon-based sensing yarns between two weaving layers,
forming an integrated textile sensing array. The TPST not only exhibits
excellent sensing sensitivity, reliability, and rapid response to
pressure and temperature stimuli but also shows robust mechanical
properties, flame resistance, and wearing comfort. Moreover, we demonstrate
the application of the TPST for continuous temperature monitoring,
human motion mapping, and vital sign monitoring. This technology offers
significant potential for enhancing autonomous rescue operations and
defense wearables.
