STRAIN SENSITIVITY OF EPOXY-QUARTZ PACKAGED SAW STRAIN SENSORS
A SAW strain sensor with new simplified Epoxy-Quartz packaging is analyzed in this paper.The strain sensitivity of sensors with Epoxy-Quartz Package is calculated with perturbation theory and finite element method theoretically.The sensitivity is close to the sensitivities of traditional AQP,which are 3.20 ppm /με and 3.32 respectively.Then an Epoxy-Quartz Packaged 433MHz SAW strain sensor is fabricated by using the epoxy EP-4 adhesive.An experimental platform is set up and the strain sensitivity of Epoxy-Quartz Packaged is measured at 20 ℃.The experimental results indicate that strain sensitivity of Epoxy-Quartz Packaged is 2.51,which almost agrees with theoretical results.Therefore,a new simplified package for SAW strain sensor with a relatively high strain sensitivity is verified in this paper.
