Abstract

In this paper, an active high temperature RF wireless pressure sensing system is proposed by combining a novel Silicon Carbide (SiC) wireless transmitter and a commercial piezoresistive pressure sensor head. The entire sensing system is capable of high temperature operation up to 450 °C. A prototype system, fabricated by using low temperature co-fire (LTCC) process, was tested from room temperature to 450 °C and the pressure signal was successfully recovered at the receiver throughout the entire temperature range.
