Modular Integrated Nanofabric Enabling Crosstalk‐Free Temperature‐Force Sensing and on‐Demand Personal Thermal Management

ABSTRACT Integrating health monitoring and thermal management capabilities into fabrics is an effective strategy for preventing thermal threats for individuals. The key challenges lie in the coupling of optical and mechanical fields, as well as in the effective decoupling of multiple physical signals. Herein, mechanics‐optics asymmetric modular design strategy is proposed to achieve high integration of crosstalk‐free temperature‐force monitoring and multi‐modes thermal managing capacities. Core of the strategy is the separation of “rigid” thermal sensitive and “soft” strain sensing nanofabrics on an elastic thermochromic phase‐changing (TCM) fabric platform. The dispersed transmission of stress significantly reduces the mutual interference of temperature‐force signals (Disturbance index < 2%), while ensuring signal sensitivity (19.80 MPa −1 and 0.603°C −1 ). In terms of optic, Te nanowires are incorporated into graphene thermosensitive ink to balance conductivity and sensitivity, thereby achieving high solar radiation absorption (A PT_sun ∼93%) and low infrared emission (ε PT ∼64%) for photothermal heating (ΔT PT ∼50°C at I solar ∼600 W/m 2 ). Moreover, TCM fabric as an elastic substrate provides radiative cooling (∼4°C lower than cotton) and resists temperature fluctuations through passive modulation of solar radiation (ΔRvis ∼36.75%) and phase‐change behavior. It is believed that this work will provide inspiration for multi‐signal decoupling and on‐demand thermal management in multifunctional integrated smart fabrics.
