Three-dimensional motion and transformation of a photoelectrochemical actuator.
A new "photoelectrochemical actuator" consisting of poly(acrylic acid)/copper gel and TiO2 nanoparticles has been developed, which undergoes reversible expansion/contraction upon UV light irradiation/termination, likely due to dissociation/formation of carboxylic group/Cu2+ binding.
