Title: Jae Hung Han: Innovator in Electromechanical Transducers and Fiber Optic Sensors

Introduction

Jae Hung Han is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of electromechanical transducers and fiber optic sensors. With a total of 2 patents, his work focuses on innovative methods for detecting and controlling structural deformations and vibrations.

Latest Patents

One of his latest patents is an electromechanical transducer and method for manufacturing the same. This invention can detect or control deformation and vibration of a structure and the flow of fluids by applying controlling forces. The electromechanical transducer comprises a base substrate to which initial stress is applied, an electro-active material layer attached to the base substrate, and electrodes installed on both sides of the electro-active material layer. This design allows for the deformation of the electro-active material layer when initial stress is removed, resulting in curvatures in both the base substrate and the electro-active material layer.

Another notable patent is the patch-type extrinsic Fabry-Perot interferometric fiber optic sensor and a real-time structural vibration monitoring method using the same. This invention combines the existing EFPI fiber optic sensor with a direction-detecting sensor to acquire strain direction information. It addresses signal distortion issues in the existing EFPI fiber optic sensor through a simplified signal processing method. The sensor includes a piezoelectric material that applies control forces and a self-sensing bridge circuit for extracting direction information, thereby extending the sensible range of strain.
