Surface-Acoustic-Wave Sensor Design for Acceleration Measurement

Sensors, 2018
We suggest a concept design of a SAW-based microaccelerometer with an original triangular-shaped console-type sensing element. Our design is particularly optimized to increase the robustness against positioning errors of the SAW resonators on the ...
