About

Koji Iwasaki is a pioneering researcher in the field of medical robotics and piezoelectric actuation, with a career spanning over three decades. His foundational work on micro robot arms, utilizing rapid deformations of piezoelectric elements (1991, 11 citations), established early principles for high-precision, miniaturized robotic systems—a cornerstone for modern surgical robotics. Iwasaki’s most significant recent contribution lies in advancing total knee arthroplasty (TKA) through robotic assistance. In his 2024 study, he elucidated the association between additional distal femoral resection and extension angle improvement during actual surgical steps with the Robot-TKA system (2 citations), providing critical insights that refine surgical precision and patient outcomes. This work bridges the gap between theoretical robotics and clinical application, demonstrating how his early innovations in micro-actuation now directly enhance orthopedic surgery. Iwasaki’s research trajectory—from fundamental piezoelectric mechanisms to practical robotic surgery—exemplifies the translational impact of engineering in medicine, offering students a model of how foundational science can evolve into life-changing clinical technologies.
