A method of manufacturing electronics using a nanoparticle ink printing method includes: synthesizing a phase change material (PCM) ink composition using hot injection to develop nanoparticles of the PCM; suspending the nanoparticles with a solvent; and printing a reconfigurable component using the PCM ink composition in additive manufacturing. Electronics includes: a substrate layer; an insulator layer printed on top of the substrate layer; a heater layer printed on top of the insulator layer; a barrier layer printed on top of one or more of the insulator layer and the heater layer; a phase change material (PCM) printed on top of the barrier layer; a connectivity layer printed on top of the PCM; and a passivation layer printed on top of one or more of the PCM and the connectivity layer.

The invention relates to a novel method for preparing materials whose properties can be manipulated after fabrication. In this process, a base material is created in a manner that provides spaces or voids which can then be filled with a modifying composition. The method is particularly useful in the manufacture of light adjustable optical elements such as intraocular lenses.
