A QCM measures very minute amounts of mass or mass variation using the piezoelectric properties of quartz crystal. When an object is placed on the surface of this sensor, the changes in the ...

Their nanoscale dimensions allow for high sensitivity, enabling the harvesting of small-scale mechanical energy, such as body movements, heartbeats, or even acoustic waves. Additionally, piezoelectric ...

For using AE sensors also as actuators, the amplifier path can be bridged and high voltage pulses up to 500V can be applied to the sensor via a pulse input ... which include the acoustic travel times ...
