Temperature sensors are one of the most fundamental sensors and are found in industrial,
environmental, and biomedical applications. The traditional approach of reading the
resistive response of Positive Temperature Coefficient thermistors at DC hindered their
adoption as wide-range temperature sensors. Here, we present a large-area thermistor,
based on a flexible and stretchable short carbon fibre incorporated Polydimethylsiloxane
composite, enabled by a radio frequency sensing interface. The radio frequency readout …
