Liquid Dielectric Zinc Tin Oxide Thin-Film Astable Multivibrator

It will take me a while to write up a complete description of the experiment, but suffice it to say that I’ve managed to cobble together a working astable multivibrator using two homemade zinc tin oxide thin-film devices as the active components in the circuit. The circuit worked for about 16 hours before the liquid dielectric circuit failed. I’ve attempted to replace the liquid dielectric with fresh material, but doing so does not repair the device. At this point I really don’t know what caused the devices to fail.

Above is the schematic of the circuit.

Above is a picture of the circuit. The zinc tin oxide thin-film devices are on the right.

Above is a graph showing the circuit’s operation over a majority of its lifetime. The data from the final hour of operation was lost when QtDMM crashed. The scale is too large to see the individual oscillations, but if you click on the image a much larger version is viewable where the individual oscillations are visible.

Above is a zoomed in graph of the last hour’s worth of collected data.

I’ll post more details soon.
