A new apparatus for measurement of capacitance change in soft materials.
We have developed an apparatus with LC resonance circuit to measure a fast capacitance change accompanied by freezing of a supercooled water droplet that was placed in a capacitor space formed by a set of a needle and a copper plate. A trace of the capacitance change obtained exhibits a first rapid increase, a gradual growth, and a final steady state. The experimental capacitance change is in good agreement with that of the capacitance calculated with the finite element method.
