We report on the development of harsh-environment surface acoustic wave sensors for wired and wireless operation. Surface acoustic wave devices with an interdigitated transducer emitter and multiple reflectors were fabricated on langasite substrates. Both wired and wireless temperature sensing was demonstrated using radar-mode (pulse) detection. Temperature resolution of better than ±0.5°C was achieved...
High temperature langasite SAW oxygen sensors using ZnO as a resistive sensing layer were fabricated and tested in a wired configuration up to 650°C, representing an important step toward future high temperature wireless sensor development. ZnO layers deposited by spin coating and RF sputtering methods were compared. The langasite SAW sensor with spin coated ZnO sensing film had strongly increasing...
Wired and wireless surface acoustic wave (SAW) sensors with langasite Euler angle (0, 138.5, 27) and (0, 138.5, 117) were fabricated for the purpose of temperature and gas sensing in high temperature combustion process. Their temperature responses were measured in pulse mode both wired to a high-temperature cable and in wireless mode attached to a dipole antenna. The observed surface acoustic wave...
