Hence, the materials show degradation behavior, which has to be taken into account for use in MEMS applications. Long cycles ... The laser beam, generated by a Helium-Neon laser with a wavelength of 632.8 nm, is split into a measurement and a reference beam. First the ... The signal from the photo detector is filtered by the lock-in amplifier and displayed on a TEKTRONIX TDS 684 A oscilloscope. Since the ... Figure 14 shows the d33 graph for a 300 nm thin PZT45/55 film. Like theanbsp;...
