(a) Schematic representation of the human iris exhibiting the tangentially contraction of sphincter muscle and the radially contraction of dilator muscle. (b) The CLCP iris with integrated polyimide-based platinum heaters contracts and expands in a way similar to that of the human iris. (c) The monomer and crosslinker used in the experiments. (d) Simulation of the magnetic field of the designed magnet with a continuous radial field in the orientation area that lies above the minimal magnetic field strength.
