Lee Receives Silver Award at Samsung Best Paper Competition

Atlanta, GA

Byunghun Lee won the Silver Award at the highly competitive 11th Samsung Electro-Mechanics Best Paper Awards. Lee is a Ph.D. student in the Georgia Tech School of Electrical and Computer Engineering (ECE).

Lee was honored for his paper entitled "A Multi-Cycle Q-Modulation Technique for Wirelessly-Powered Biomedical Implants,” which was coauthored with fellow ECE Ph.D. student Pyungwoo Yeon and ECE Associate Professor Maysam Ghovanloo, who advises both students and serves as director of the GT-Bionics Lab.

This paper presents a new method, called multi-cycle Q-modulation, which can be used in wireless power transmission (WPT) to modulate the quality factor (Q) of the receiver (Rx) coil and dynamically optimize the load impedance to maximize the power transfer efficiency (PTE) in two-coil links. This new multi-cycle Q-modulation method can be used to maintain high PTE in wirelessly powered applications that operate in dynamic environments with variable loading, such as implantable medical devices.
