Abstract

See full text

An RC filter that is tunable in terms of its cut-off frequency comprising a drop placed on one or more dielectric layers, a conducting layer underneath the dielectric layer, a nonconducting layer underneath the conducting layer, and an external resistor attached to the drop via an electrode, wherein the cut-off frequency of the filter is tuned by changing the shape or composition of the drop and methods of using the filter as a detector.
