Title: Innovations of Seunghyun Kim in Piezoelectric Technology

Introduction

Seunghyun Kim is a notable inventor based in Bristol, RI (US), recognized for his contributions to the field of piezoelectric technology. He holds 4 patents that showcase his innovative approach to developing advanced printhead systems.

Latest Patents

One of his latest patents is for a lead-free piezo printhead using thinned bulk material. This invention discloses an apparatus for a lead-free piezoelectric ink-jet printhead. Piezoelectric printheads, while more expensive, are favored because they can utilize a wider variety of inks. The design includes a diaphragm, a plurality of piezoelectric actuators made from lead-free piezoelectric material, at least one nozzle, at least one ink chamber, a top electrode, and a drive circuit. The diaphragm's deflection within the body chamber generates a pressure pulse that ejects a drop of liquid from the nozzle. This exemplary embodiment operates at smaller thicknesses and significantly higher electric fields, along with methods for manufacturing such printheads.
