Dr. Ha is the first author of a research article on a Robotic Biopsy Endoscope with Magnetic 5-DOF Locomotion and a Retractable Biopsy Punch.

Co-authors of the research included Hoang Manh Cuong, Nguyen Kim Tien, Nguyen Van Du, Jayoung Kim, Eunpyo Choi, Seungmin Bang, Byungjeon Kang, Jong-Oh Park and Chang-Sei Kim.

The group of researchers present a novel wireless biopsy CE employing active five-degree-of-freedom locomotion and a biopsy-needle punching mechanism for the histological analysis of the intestinal tract.

A medical biopsy punch is attached to a screw mechanism, which can be magnetically actuated to extrude and retract the biopsy tool for tissue extraction. The external magnetic field from an electromagnetic actuation (EMA) system is utilized to actuate the screw mechanism and harvest biopsy tissue; therefore, the proposed system consumes no onboard energy of the capsule endoscope.

This design enables the observation of the biopsy process through the capsule’s camera.

Dr. Ha is an alumnus of Advanced Program in Mechatronics Engineering of Hanoi University of Science & Technology and former PhD student at Robot Research Initiative of Robotics Research Institute of Chonnam National University in Gwangju, the Republic Korea.

He is currently working as a director of the editorial services department of V-KOOKMIN Joint Stock Company.

The Best Paper Awards aims to recognize published outstanding papers preselected by the Micromachines Editorial Office on the basis of the number of citations and downloads from the website. The winners from the nominations were determined by an awards committee, the Editor-in-Chief, together with the Editorial Office.
