“…When heated or cooled, the thermochromic materials will possess a thermal memory function, then the color of those will emerge pronounced changes. Comparing the color of thermochromic materials with that of standard color, it is easy and quick to know the surface temperature of measured objects ( Li et al, 2019 ; Zhang et al, 2017 ; Geng et al, 2018 ; He et al, 2019 ).…”

Temperature reflects the balance between production and dissipate of heat. Flexible temperature sensors are primary sensors used for temperature monitoring. To obtain real-time and accurate information of temperature, different flexible temperature sensors are developed according to the principle of flexible resistance temperature detector (FRTC), flexible thermocouple, flexible thermistor and flexible thermochromic, showing great potential in energy conversion and storage. In order to obtain high integration and multifunction, various flexible temperature sensors are studied and optimized, including active-matrix flexible temperature sensor, self-powered flexible temperature sensor, self-healing flexible temperature sensor and self-cleaning flexible temperature sensor. This review focuses on the structure, material, fabrication and performance of flexible temperature sensors. Also, some typical applications of flexible temperature sensors are discussed and summarized.

Wearable sensors are emerging as a new technology to detect physiological and biochemical markers for remote health monitoring. By measuring vital signs such as respiratory rate, body temperature, and blood oxygen level, wearable sensors offer tremendous potential for the noninvasive and early diagnosis of numerous diseases such as Covid‐19. Over the past decade, significant progress has been made to develop wearable sensors with high sensitivity, accuracy, flexibility, and stretchability, bringing to reality a new paradigm of remote health monitoring. In this review paper, the latest advances in wearable sensor systems that can measure vital signs at an accuracy level matching those of point‐of‐care tests are presented. In particular, the focus of this review is placed on wearable sensors for measuring respiratory behavior, body temperature, and blood oxygen level, which are identified as the critical signals for diagnosing and monitoring Covid‐19. Various designs based on different materials and working mechanisms are summarized. This review is concluded by identifying the remaining challenges and future opportunities for this emerging field.

“…[ 30–34 ] The most commonly used method is to incorporate the soft substrates, such as polydimethylsiloxane (PDMS), [ 35,36 ] polyimide (PI) [ 37,38 ] with thermoresponsive materials such as graphene/graphene nanoplates, [ 30,39 ] carbon nanotubes (CNTs), [ 7,40 ] metal nanowires/nanosheets. [ 38,41 ] The introduction of inorganic fillers limits the thermoresponsibility and stretchability of these sensors mentioned above, [ 20 ] and the self‐healing performance will also be limited since the nanofillers such as graphene and CNTs could hamper the reassociation of dynamic chemical bonds in the polymer mainchains. [ 42 ] In contrast, hydrogels and ionic gels with robust, self‐healable, stretchable, and other responsive performances [ 7,43–47 ] have aroused much interest due to their wide applications in the field of wearable and flexible electronic devices.…”

Temperature sensors have great potential applications for the body temperature monitoring, it's a big challenge to prepare sensors with high sensitivity and maintaining adaptive properties for the long‐term applications. In this study, an organohydrogel for the temperature sensor is achieved via glycerol solvent replacement of water in the poly‐N‐acryloyl glycinamide (PNAGA)/carrageenans double network (DN) hydrogel. Owing to successful construction of strong multiple hydrogen bonding (H‐bonding) interactions among PNAGA chains and carrageenans, the PNAGA‐based glycerol gel (Gly‐gel) sensor exhibits excellent thermal stabilities, possesses high sensitivities (2% °C) resulted from the acceleration of mobility of ions at high temperature and shows high tensile strength of about 4 MPa without chemical crosslinkers (higher than most reported organohydrogel‐based temperature sensor) with self‐healable performance. In addition, the double network of Gly‐gel enables it excellent dual and triple shape memory performance with high fixing ratio (Rf, 88%), recovery ratio (Rr, 95%) under large deformations (above 80%) that are beneficial to the potential application in wearable devices. Different from previous temperature sensors, this work provides a facile approach to prepare overly sensitive temperature sensors with the combination of excellent thermal stability, high tensile strength and adaptive properties via the solvent replacement of hydrogel.
