“…Besides these synthetic materials, some natural fibers or textile materials have been developed for substrate layer in flexible sensors due to their light weight, shape‐adaptive conformability, and distinguished air permeability. [ 16,18,27,35 ] For instance, silk fiber represents a distinguished and abundant biomaterial and it performs decent mechanical properties and favorable durable deformation. And silk can be further modified or treated to realize conductive synthetic composites.…”

changes in human body temperature are the first medical diagnostic assessment for the recent on-going COVID-19 pandemic. [1,2] Some emotion-related bodily sensations can also be observed by analyzing the subtle change of body temperature. [3] Hence, it is particularly important to real-time detect human body temperature and monitor external environmental temperature change to establish a smart healthcare system and create a comfortable living condition for human beings.Numerous temperature detectors have been developed to detect temperature through certain physical parameter changes, including mercury thermometers, infrared thermometers, and flexible temperature sensors. Specifically, a mercury thermometer can accurately measure the human body temperature based on the principle of heat-expansion and cold-contraction, however, it takes a much longer time to finish the measurement, and the glass maybe easily be broken, which will pollute the environment and pose potential harm risk to the users. An infrared thermometer is a thermometer with a wide range, fast response, and high sensitivity, which infers temperature from the thermal radiation, sometimes called black-body radiation emitted by human beings. Unfavorably, it is prone to be affected by human emissivity and thus the temperature measurement accuracy is always insufficient for practical application. Alternatively, flexible temperature sensors have attracted intense interest due to their favorable proprieties, such as high sensitivity, good accuracy, fast response, and friendly interface. Benefiting from the softness with conformability, flexible temperature sensors can be directly attached to human skin with ease to record both human body temperature and external environmental temperature in a continuous and long-term manner. Flexible temperature sensors are generally divided into thermo-sensitive sensors, thermo-resistive sensors, and thermoelectric sensors according to the change of electrical resistance in conductive materials or change of surface charge in thermoelectric materials. [4,5] Temperature variations can be precisely captured and these timely information are then transmitted to the human nervous system, providing a very useful tool to sense and respond to the environmental or physiological stimuli. Consequently, flexible temperature sensors open up many promising opportunities in emerging personal healthcare, [6,7] electronic skin, [8] artificial intelligence, [5,9] and next-generation smart robots. [10] There are various constructing materials for flexible temperature sensors, such as films, [11] rubbers, [12] hydrogels, [13] and Accurate and real-time detection of human body temperature changes is crucial to understand thermal homeostasis, to access complex health conditions, and to further build a smart healthcare system. Recent years have seen temperature sensors open up many potential applications in electronic skin, artificial intelligence, and next-generation smart robots. Currently, traditional mercury and infrared thermometers are ext...

“…Considering the biosafety, temperature difference response ability, and ROS generation requirements, SnSe was selected as PEDT nanomaterials for the advantages of good biosafety, good photothermal conversion performance, superior thermoelectric efficiency, and appropriate valence/conduction band potentials. After combining Au nanoparticles onto the surface of SnSe, the photothermal conversion property was improved, and the migration and separation properties of e – and h + , which was activated by thermoelectric effects, could be significantly improved due to the potential difference between electron acceptor Au-NPs and SnSe nanosemiconductors, resulting in promoted h + –H 2 O half-reaction efficiency ( Wang et al, 2020a ; Zhang et al, 2020 ; Wang et al, 2021 ). Moreover, e – -rich Au-NPs could catalyze tumor endogenous H 2 O 2 into ∙OH with high reactivity, together with h + –H 2 O-induced ·OH generation.…”

Endogenic heat shock proteins and uneven local heat distribution are two main problems in traditional tumor hyperthermia therapy strategies. Aiming at solving these problems, we designed Au–SnSe–PVP nanomaterials (ASNPs) by modifying Au nanoparticles (Au-NPs) and biocompatible PVP on SnSe nanorods via a new reactive oxygen species production strategy. The ASNPs with excellent photothermal conversion performance can produce thermoelectric effects in response to temperature differences during photothermal conversion. The modification of Au-NPs can attract free electron (e–) to accumulate and promote the separation of e– and holes (h+) in the thermoelectric process, thereby further promoting e–-rich Au-NPs-induced H2O2 homolysis and h+–H2O half-reaction to generate hydroxyl radicals, realizing the synergistic application of photothermal therapy and pyroelectric dynamic therapy in tumor treatment.

The rational design and construction of efficient and inexpensive bifunctional oxygen electrocatalysts are highly desirable for the development of rechargeable Zn–air batteries (ZABs). Although single‐atom Fe sites anchored on N‐doped carbon catalysts (Fe1/NC) ensure high oxygen reduction reaction activity, their unitary atomically dispersed active center faces difficult condition in catalyzing oxygen evolution reaction simultaneously. Herein, a composite catalyst containing heterointerface between Fe1/NC and selenides ((Fe,Co)Se2) is constructed. The obtained (Fe,Co)Se2@Fe1/NC exhibits extremely narrow potential gap of 0.616 V and remarkable stability in alkaline media, outperforming the benchmark catalysts (Pt/C+RuO2: 0.720 V). Experimental results and density functional theory calculations reveal that heterointerface between Fe1/NC and (Fe,Co)Se2 accelerates the electron transfer and provides more moderate adsorption sites, which endow (Fe,Co)Se2@Fe1/NC with extremely high bifunctional oxygen catalytic activity. This study not only provides a superior bifunctional catalyst for ZABs, but also enriches the application of single‐atom catalysts in multifunctional energy storage and conversion devices.
