Patent ID: 8397373

Claim:
A method for manufacturing a multilayer polymeric actuator, comprising: arranging a winding core rotating around a central axis thereof; winding a dielectric film of polymeric material around the winding core; during winding, applying a conductive material on a dielectric film exposed face being wound around the winding core, wherein said applying occurs intermittently according to a set sequence, and according to a first and a second geometrical application pattern mutually alternated at each winding turn, so as to form a roll comprising at least one circumferentially localized zone formed by dielectric film layers radially alternated with conductive material layers; radially cutting the roll at the ends of said circumferentially localized zone, so as to be able to take out a corresponding stack formed by the dielectric film layers alternated to the conductive material layers; and connecting in an electrically conductive manner the conductive material layers having the first geometrical application pattern one to the other and, separately from these, the conductive material layers having the second geometrical application pattern one to the other.
