“…The response time is consistent with the thermal diffusion response time of the device (∼1.7 s), indicating that the temperature sensing response time is limited by the thermal diffusivity of the composite material (0.66 mm 2 s −1 ). In addition, this temperature sensing response time, which is slightly affected by the temperature and pressure ( Supplementary Figs 18 and 19 ), is consistent with those of many commercial and previously reported temperature sensors 39 40 . It is worth noting that both the sensitivity and response time of our fabricated devices can meet the requirements of many artificial intelligent systems.…”

Skin-like temperature- and pressure-sensing capabilities are essential features for the next generation of artificial intelligent products. Previous studies of e-skin and smart elements have focused on flexible pressure sensors, whereas the simultaneous and sensitive detection of temperature and pressure with a single device remains a challenge. Here we report developing flexible dual-parameter temperature–pressure sensors based on microstructure-frame-supported organic thermoelectric (MFSOTE) materials. The effective transduction of temperature and pressure stimuli into two independent electrical signals permits the instantaneous sensing of temperature and pressure with an accurate temperature resolution of <0.1 K and a high-pressure-sensing sensitivity of up to 28.9 kPa−1. More importantly, these dual-parameter sensors can be self-powered with outstanding sensing performance. The excellent sensing properties of MFSOTE-based devices, together with their unique advantages of low cost and large-area fabrication, make MFSOTE materials possess promising applications in e-skin and health-monitoring elements.

Human skin and hair can simultaneously feel pressure, temperature, humidity, strain, and fl ow-great inspirations for applications such as artifi cial skins for burn and acid victims, robotics, and vehicular technology. Previous efforts in this direction use sophisticated materials or processes. Chemically functionalized, inkjet printed or vacuum-technology-processed papers albeit cheap have shown limited functionalities. Thus, performance and/or functionalities per cost have been limited. Here, a scalable "garage" fabrication approach is shown using off-the-shelf inexpensive household elements such as aluminum foil, scotch tapes, sticky-notes, napkins, and sponges to build "paper skin" with simultaneous real-time sensing capability of pressure, temperature, humidity, proximity, pH, and fl ow. Enabling the basic principles of porosity, adsorption, and dimensions of these materials, a fully functioning distributed sensor network platform is reported, which, for the fi rst time, can sense the vitals of its carrier (body temperature, blood pressure, heart rate, and skin hydration) and the surrounding environment.

“…The response time and rest time are two important indexes for judging the sensitivity of sensors. As shown in Figure e, the calculated response time is 1.05 s. The response time is shorter than that of many previously reported temperature sensors, such as self‐powered porous polyurethane supported organic thermoelectric materials (1.7 s), and is consistent with the zirconate titanate microwire self‐powered temperature sensors (0.9 s) . We also note that the response time is longer than the other sensors, such as pressure sensors and some temperature sensor .…”

“…[23] An important application of the Ag 2 Te nanowire thermoelectric generator is working as a self-powered temperature sensor. As shown in Figure 6e, the calculated response time is 1.05 s. The response time is shorter than that of many previously reported temperature sensors, [24] such as self-powered porous polyurethane supported organic thermoelectric materials (1.7 s), [25] and is consistent with the zirconate titanate microwire self-powered temperature sensors (0.9 s). The temperature variation can be detected, when a finger touched/untouched the sensor (Figure 6b).…”

Flexible thermoelectric materials that enable harvesting electricity from human body heat or an ambient temperature gradient have potential applications in self‐powered flexible wearable electronics. The development of more efficient and flexible n‐type thermoelectric materials, however, is highly desired but challenging. Herein, reported is a nylon substrate supported fabric silver telluride (Ag2Te) nanowire network used as flexible n‐type thermoelectric materials, by the combination of vacuum filtrated assembly and mechanical pressing method. The prepared silver telluride nanowire films show optimal thermoelectric properties with the Seebeck coefficient of −129.5 µV K−1 and electrical conductivity of 187.78 S cm−1, leading to the highest power factor of 315.1 µW m−1 K2. Owing to the elimination of Peierls stress in the fabrics interlocking structure, the silver telluride nanowire films exhibit good flexibility, as the thermoelectric properties only have a change below 10% after 500 bending cycles. Based on the silver telluride nanowire film, a flexible self‐powered temperature sensor is fabricated for detecting the temperature from a human finger. The sensor shows high sensitivity that its response time and reset time are about 1.05 and 2.1 s, respectively. The results imply that silver telluride nanowire films have great potential applications in flexible thermoelectric energy conversion and self‐powered temperature sensing.
