About
Barbara Watson is a pioneering researcher in the field of micro-robotics, with a specialized focus on piezoelectric ultrasonic micro-motors for biomedical applications. Her work addresses one of the most critical challenges in minimally invasive surgery: the development of practical, high-performance actuators small enough to power micro-robots inside the human body. Watson’s major contributions include the design and experimental validation of the world’s smallest piezoelectric ultrasonic resonant micro-motors, with stators as small as 241 µm in diameter and overall volumes under 1 mm³. Her 2010 paper on a micro-motor suitable for *in vivo* micro-robotic applications (26 citations) demonstrated a start-up torque of 1.2 nN·m and peak output power of 0.25 µW, while her 2009 study (21 citations) proved that such motors could be fabricated and operated reliably at the sub-millimeter scale. These achievements provide a foundational solution for powering next-generation medical micro-bots, enabling procedures that were previously impossible due to the lack of suitable micro-actuators. Watson’s work is essential reading for researchers in micro-electromechanical systems (MEMS) and surgical robotics.
