He has made significant contributions to the field of device manufacturing, particularly in the development of PDMS devices and ionic transistors. With a total of 2 patents to his name, Han's work showcases innovative approaches to material science and engineering.

Latest Patents

Han's latest patents include a method for manufacturing PDMS devices and an open-junction ionic transistor. The method for manufacturing a PDMS device involves surface treating the entire surface of a pattern with a thiol group (—SH). This allows a hydrogel to be connected to the surface of the pattern by a covalent bond under ultraviolet rays. The resulting PDMS device maintains its shape stably without swelling or desorption of the hydrogel, even when an electrolyte is filled in the pattern.

The open-junction ionic transistor patent describes a device that includes a substrate, a p-type gel, and an n-type gel formed as polyelectrolyte gels on the substrate. The design features reservoirs and an encapsulation layer, with an injection unit for ion input. When a reverse bias voltage is applied, the ion input is amplified, generating an ionic current peak.
