Abstract
A method for manufacturing a multilayer polymeric actuator includes the following steps: arranging a rotating winding core; winding a dielectric film of polymeric material around the winding core; during winding, applying a conductive material on the dielectric film exposed face, in which the application occurs intermittently according to a pre-established sequence, and according to a first and a second geometrical application pattern mutually alternated at each winding turn, so as to form a roll; radially cutting the roll at the ends of a circumferentially localized zone; and connecting a conductive material layers having the first geometrical application pattern one to the other and the conductive material layers having the second geometrical application pattern one to the other.
