1. A device for imaging electrical activity of a sample, comprising:
a PDLC film of polymer in which droplets of liquid crystal are dispersed,
a transparent fluidic component wherein at least one cavity adapted to contain the sample is arranged,
a transparent reference electrode,
the PDLC film being arranged between said 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 said region of the PDLC film.
