Characterizing Vibrating Cantilevers for Liquid Viscosity and Density Sensing
Figure 1
(a) PZT bending actuator with
attached tip. The bending actuator consists of a carbon fiber substrate and two
piezoelectric layers. The electrodes (1, 2, 3) allow for excitation and readout
of the sensor. (b) Applying a voltage to the upper layer leads to contraction
or elongation of the upper layer as indicated by the arrows.
