Abstract
A device for imaging electrical activity of a sample, includes a polymer film in which liquid crystal droplets are dispersed, referred to as the PDLC film, a transparent fluidic component in which at least one cavity adapted to contain the sample is arranged, a transparent reference electrode, the PDLC film being arranged between the at least one cavity and the reference electrode and configured to convert an electric field created in a region of the PDLC film in response to an electric potential generated by the sample into a variation in transparency of the region of the PDLC film.
