Surface Acoustic Wave (SAW) Resonator as Mass Sensor in Diagnostics

Surface Acoustic Wave (SAW) devices are used in biosensors, gas, and chemical sensors because of their sensitivity to mass perturbations. SAW devices resonate and generate acoustic waves that are converted to electric signals, and vice versa, by the use of Interdigital Transducers or IDTs. The electric signals are then converted to mechanical energy...
