Artificial muscles formed from conductive polymer - non- conductive polymer multilayer structures. By means of the procedures described, a conductive polymer - non-conductive flexible polymer - conductive polymer multilayer structure can be produced, such that the system is in a condition to be introduced into an electrolyte and to operate by means of the passage of current. When the passage of current is allowed to be established by means of a potential, a multilayer conductive - non-conductive - conductive - non-conductive - conductive polymer is produced. The system is in a condition to be polarised and operate within an electrolyte. Either of the two foregoing devices can be surrounded by a sheet of solid flexible polyelectrolyte, by a sheet of a gel in which there are dissolved ions. The assembly is sealed with a flexible material giving the devices in figure 1. Multilayer structures can be constructed whose total thickness falls within the range of 20 μm and one millimetre. The association of diverse multilayer structures such as 1.a (without the sealed material in the middle) can give rise to thicker systems, although with considerable mechanical and adherence problems. The behaviour of the system is that of an artificial muscle: an electric current causes chemical oxidative or reductive reactions within the two polymeric conductor films, giving rise to volume changes within the same. The volume change is transformed into mechanical energy. <IMAGE>
