Smart textile with capabilities to sense different stimuli like temperature, pressure etc. are of considerable interest in applications such as sports, fashion, healthcare and robotics etc. The seamless integration of various sensors is desired for effective use of smart textiles in these applications. To this end, here, we present a yarn based wireless temperature sensor developed by modifying a P(VDF-TrFE) coated stainless steel yarn with vanadium pentoxide (V 2 O 5 ) nanowires (NWs). The current-voltage (I-V) characteristics and the temperature sensing performance of the devices are evaluated between 5-50°C with a step increase of 5°C. The unpacked device exhibits a sensitivity of 3.7 %/°C with a response time of 9s. The device is encapsulated with nanosilica/epoxy polymeric layer and its influence on sensors performance is also analyzed. After encapsulation, the device showed more linear response, but with slightly reduced sensitivity of 2.18 %/°C. Moreover, the effect of mechanical bending cycles on sensing performance of packaged device is studied. The sensor showed linear response even after 2000 bending cycles, but sensitivity was reduced to 1.257%/°C. Finally, the temperature sensor data is wirelessly transferred to demonstrate the potential use of developed sensors in above applications.
