Abstract
Conference Title: 2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS) Conference Start Date: 2015, Aug. 2 Conference End Date: 2015, Aug. 5 Conference Location: Fort Collins, CO, USA In this paper, a capacitive temperature sensor based on polyvinylidene fluoride (PVDF) capacitor is explored. The PVDF capacitor is characterized below its Curie temperature. The capacitance of the PVDF capacitor changes vs temperature with a sensitivity of 16pF/°C. The linearity measurement of the capacitance-temperature relation shows less than 0.7°C error from a best fit straight line. An LC oscillator based temperature sensor is demonstrated based on this capacitor.
