“…In literature, temperature sensors with various response and recovery times have been widely reported for measurement of the temperature variations either through direct contact with the heat source or remotely through radiations [15,[18][19][20]. Temperature sensors utilizing different materials and technologies such as thermocouples, resistive, thermistor, infrared, and semiconductor sensors have been previously reported [21][22][23][24][25].…”

Temperature sensors with good mechanical flexibility, high sensitivity, fast response and recovery time are essential features for real time measurements by electronic Skin (eSkin). This paper presents the fabrication and characterization of a flexible temperature sensor using PEDOT: PSS and carbon nanotube (CNT) at 1:1 mixing ratio. In order to establish the performance enhancement capability of this composition, a comparative study was carried out. This was done by fabricating two flexible temperature sensors each on ~175µm-thick PVC substrate using only CNT and then with CNT/PEDOT: PSS polymer composite following simple drop casting technique. Both sensors show good sensitivity ~0.27(%)ºC -1 )) for CNT and ~0.64(%)ºC -1 )) for CNT/PEDOT: PSS for temperatures varying from 20ºC to 80ºC. Although both the sensors, CNT and CNT/PEDOT: PSS composite revealed fast response and recovery time, the latter shows a higher sensitivity (~0.64 (%)ºC -1 )). Further, a comparison of the sensor made with CNT/PEDOT: PSS with similar works in literature reveals that the presented sensor exhibits relatively faster response (~4.8s) and recovery (~2.5s) time. This response enhancement can provide a biomimetic eSkin with unique feature.

“…Here the active electrode (PEDOT: PSS) is a p‐type semiconductor in which increasing temperature causes excitation of the electrons from the conduction band (CB) to the valence band (VB). [ 36–38 ] This thermal energy creates a hole in the VB and the material shows a negative temperature coefficient of the resistance characteristics. The magnitude of the resistance variation could be varied by changing the conductivity of PEDOT: PSS, for example, by varying the EG concentration and the dimension of the electrode.…”

Environmentally friendly energy devices and systems are of increasing interest for the circular economy and sustainable information and communications technology. To this end, an energy‐autonomous system comprised of natural jute fiber‐based supercapacitor (SC) and sensors (temperature and humidity) is presented. This material is coated with poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)/single‐walled carbon nanotubes as the electrode and cellulose‐based material as a separator. Further, a newly prepared hydroxyethyl cellulose‐potassium chloride based gel is used as the electrolyte. The observed capacitance is nearly twice the value reported for similar SCs. The energy and power densities of the presented SC are 0.712 μWh cm−1 and 3.85 µW cm−1, respectively at a capacitance of 8.65 mF cm−1 and an applied current of 0.1 mA. The fabricated temperature sensor shows a relative change in response of 0.23% °C−1 from 24 to 35 °C and the humidity sensor exhibits a sensitivity of 1.5 Ω/%RH (relative change of 0.20%) up to 50%RH. Developed using sustainable and biocompatible materials, the presented SC can power the jute‐fiber based sensors, thus demonstrating an attractive eco‐friendly solution for applications such as wearables, grain sacks, and bags.

Flexible textile‐based sensors are versatile alternatives that can be comfortably worn and can detect a broad range of body and environment temperatures. Furthermore, they are becoming more essential due to the recent rise in the use of wearable customized gadgets, wearable clothing, sports, medical and soft robotics. Typically made from rigid materials like metals or semiconductors, traditional temperature sensors are heavy, inflexible, and difficult to wear since they can only endure very slight variations in their physical shape to be placed on any irregularly shaped object. In this review, we discuss developments in textile temperature sensors with a focus on their performance, fabrication techniques, advances in various materials, and applications, such as wearable monitoring and sports. Moreover, an in‐depth analysis of different performance parameters has also been presented. Lastly, in order to provide useful guidance and directions for future study, we conclude by outlining the current limitations of this field, and future recommendations for the scientific community to further explore other facets of textile temperature devices.This article is protected by copyright.
