摘要：Passive wireless sensors with the capability of mutliparameter measurement have valued industrial applications for monitoring mechanical structure operating parameters in harsh or high-temperature work environments. The passive wireless microwave sensors with a substrate-integrated waveguide (SIW) structure and a complementary split-ring resonator (CSRR) were designed and built to simultaneously detect temperatures and pressures. Incorporating CSRR into the SIW structure effectively enhances sensitivity of these CSRR-SIW sensors. Theoretical calculations and numerical simulations were conducted to optimize the sensor's structural geometries and dimensions. The sensor was fabricated by a stereo lithography appearance (SLA)-based 3-D printing and laser-assisted selective electroless-plating (LA-SEP), which is highly efficient and scalable. Experimental results demonstrate that the resonant frequencies of the as-fabricated sensors closely matched the simulation results, with a deviation of less than 3.76% at room temperature. The CSRR-SIW sensor exhibits sensitivities of 125.219 kHz/degrees C and 121.575 kHz/kPa for temperature and pressure, respectively. We investigated and proposed a decoupling method to separate the coupled sensing signals of temperature and pressure for engineering applications. This method aims to enhance signal accuracy and reliability in practical scenarios.
