Patent ID: 10634635

Abstract:
A dielectric constant microscope to observe a shape of a micro organic specimen includes first and second insulating films that are disposed to oppose each other such that the organic specimen along with the solution is interposed therebetween, and application-side conductive films P1 to Pn (where n is an integer greater than 1). The application-side conductive films are separated from each other on an outward surface of the first insulating film. Additionally, the dielectric constant microscope includes measurement-side conductive films p1 to pm (where m is an integer greater than 1) that are separated from each other on an outward surface of the second insulating film. Input signals Sf1 to Sfn having potential change at different frequencies are applied to the application-side conductive films P1 to Pn, potential change is measured for each of the measurement-side conductive films p1 to pm, and the organic specimen is visualized from a dielectric constant distribution between the first and second insulating films obtained by separating the potential change depending on the frequencies.
