Abstract:
1. An electric field control device that applies electric fields to an electric field application subject, including: a first electrode and a second electrode that generate the electric fields; a frame that is arranged around the first electrode and second electrode, and is connected to the first electrode and second electrode, the first electrode, the second electrode, and the frame forming an electrode unit, wherein the frame is so arranged as to symmetrically enclose the first electrode with the first electrode being the center, wherein the frame is set in the form of fences with clearances between the fences; an opening that is formed at one end of the frame; output means for outputting a first signal to the first electrode, and outputting a second signal to the second electrode, a detection unit for detecting an impedance for the electrode unit through a quasi-electrostatic field.
