Title: Quang Hung Tran: Innovator in Magnetic Sensor Technology

Introduction

Quang Hung Tran is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of magnetic sensor technology, holding two patents that showcase his innovative approach to detecting magnetic fields.

Latest Patents

His latest patents include a magnetic sensor that features a magnetic layer of closed loop shape. This sensor is designed to detect magnetic fields effectively. It includes a pair of current terminals that face each other and contact the closed loop, allowing for current input and output. Additionally, it has a pair of voltage terminals that also face each other, from which the output voltage is detected. The sensor utilizes both an anisotropic magnetoresistance effect (AME) and a planar Hall effect (PHE) to contribute to the output voltage. Notably, the hysteresis of the output voltage is minimized through the exchange coupling of a ferromagnetic layer with a ferromagnetic-antiferromagnetic layer structure and a ferromagnetic-metal-antiferromagnetic layer structure. This innovation stabilizes the output voltage and enhances sensitivity.

Another significant patent is a micromagnetometry detection system and method for detecting magnetic signatures of magnetic materials. This system is capable of detecting very small quantities of magnetic particles. It comprises a first magnetic hybrid AMR/PHR multiring sensor that uses a Wheatstone bridge electrical configuration, along with a current source and a voltage measurement device. The system includes a set of magnetic particles deposited on the first magnetic sensor and a processing unit that detects magnetic flux shifts representative of the presence of these particles. The micromagnetometry system also features means for creating a magnetic excitation field, which generates a stray magnetic field oscillating at a constant frequency.
