A planar device with wells addressing automates by dynamic ELECTROWETTING

The invention relates to a method for analyzing a liquid drop (2) comprising: - contacting a drop of the liquid with a hydrophobic surface (8), - the displacement of the droplet on this surface by electrowetting, in order to bring a site (24, 26, 28) for measurement of electrical activity, in which is disposed a conductive solution (42), - measurement of said electrical activity.
