Low dimension poly(3,4-ethylenedioxythiophene) poly (styrenesulfonate) (PEDOT: PSS) has been applied as resistor-type devices for temperature sensing applications. However, their response speed and thermal sensitivity is still not good enough for practical application. In this work, we proposed a new strategy to improve the thermal sensing performa...

... Due to progress in materials science and manufacturing capacity, wearable devices [46][47][48], a type of portable electronic equipment that integrates sensors, have received considerable interest and displayed a great increase in both research and commercialization, including those integrated on watches, bracelets, glasses, clothes, shoes, socks, necklaces, and other accessories, as well as directly attached to the skin of the human body [49,50]. Wearable devices can monitor personal physiological statuses and environmental conditions through detecting health-related physical, chemical, and biological signals [51][52][53][54], such as respiration, temperature, heartbeat, blood pressure, exhaled breath, blood glucose [55][56][57][58][59][60]. Among various wearable sensors, the wearable gas sensor has become an emerging area of critical importance because there is an increasing demand for monitoring exhaled and surrounding air in real-time to achieve breath diagnosis and identify potential environmental hazards, respectively. ...
... In order to cope with the timely detection of toxic and hazardous gases and to prevent the related diagnosis of respiratory injuries and diseases, the active development of low-cost, durable, high-performance gas sensors has become the focus of current research [3,4]. With the development of the "Internet of Things" and artificial neural networks, the design of wearable gas sensors provides a promising strategy to broaden the practical applications by combining real-time monitoring and big data analysis, which allows the device applicable to the early detection of any health hazards [5][6][7][8]. Therefore, exploring wearable devices with improved room temperature detection ability ranks as the key to expand the field of gas sensing. ...
... Jiang et al. used soft scale nano lithography to design a sensor array with PEDOT:PSS nanowires [56]. This sensor array was designed for environmental monitoring, industrial process and as a breath biomarker and tested against various VOCs such as ketones, alcohols, alkanes, and amines. ...
... For this reason, graphene/polymer composites were also conducted in the investigations of gas sensing. Tang et al. reported an e-nose type chemiresistive gas sensor composed of graphene oxide doped poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT: PSS) nanowires fabricated by soft lithography [118] . Large scale and well-defined sub 100 nm nanowires with different weight percentages of GO were arrayed to tune volatile organic compounds (VOCs) sensor responses, which were utilized to constitute unique identification codes for ethanol, n-hexane, acetone, and pxylene and realized the discrimination of different VOCs. ...
... The PPy-ClO 4 showed a high sensitivity to methanol, ethanol, 1-propanol and 2-propanol, respectively, and was capable to determine residual methanol in biodiesel samples (Babaei and Alizadeh, 2013). Volatile organic compounds were also determined by a PEDOT:PSS nanowire array, which in association with chemometric tools allowed the classification of the results according to the organic compound, enhancing the ability of the PEDOT:PSS nanowires sensor to act as an e-nose system, being able to recognize and separate different compounds (Tang et al., 2017). ...
... 52 Therefore, CPs have a high capacitance. 53 CPs are used in the manufacture of conductive textiles because they give the fabric the feel of cloth and are lightweight, and the mechanical properties of the fabric are not affected by a thin coating of CP. 1,20,21,24,27,34,36,42,45 They have also been used in applications such as thin-film transistors, 54 sensors, 55,56 displays, 57 electrochromic devices, 58−60 supercapacitors, 61,62 light-emitting diodes, 63 and field-effect transistors 64,65 and in wide applications in energy conversion, storage devices, and solar cells 66−68 ...
