Three devices were built to measure the impact of PDMS slab positioning and IDT quality on the piezoelectric effect propagating through the LiNbO3 substrate. A sine-wave of variable amplitude between 0.5 -5 V at 10 kHz was fed to the amplifier and the resulting peak-to-peak voltages were measured across the IDTs. Measurements were performed using an oscilloscope (Voltcraft DSO-1062D 2 Channel Digital Storage, Germany) using a standard BNC cord connected to a 100x probe.
