Vibrations, acoustic mass sensors

The addition of mass provides the means of transduction for many chemical sensors, including surface acoustic wave (SAW) devices, quartz crystal microbalances (QCM), and microcantilevers. In all these devices, the mass addition either perturbs the vibration, oscillations, or deflection within the transducer. The mode of transduction in an optical interferometer can also be linked to mass addition the sensor s response is altered by refractive index changes in the material being monitored. It is possible that this change can be elicited solely from refractive index changes without the addition of mass, although in sensing a particular... [Pg.96]

This works on the principle that any change in the environment concentration is reflected as a change in mass of the sensing interface which is then measured as a variation in vibration frequency. Sensors working by this principle are alternately termed surface acoustic wave (SAW) resonators. ... [Pg.379]
