About

Sabyasachi Sahoo’s research centers on biomechatronics and rehabilitation robotics, with a particular focus on prosthetic hand design and control. His major contribution lies in the bond graph modelling of tendon-driven prosthetic hand fingers, a framework that enables both motion and impedance control—critical for achieving natural, adaptive grasps. By modeling the human finger’s complex three-link structure and its multiple degrees of freedom, Sahoo’s work addresses the challenge of replicating dexterous hand function in prosthetics. His 2016 paper on this topic, though early in its citation impact, lays foundational groundwork for integrating dynamic system modeling with prosthetic control strategies. Sahoo’s approach stands out for its emphasis on impedance modulation, which allows prosthetic fingers to adjust stiffness and damping in real time—mimicking the human hand’s ability to switch between delicate and power grasps. This work is especially relevant for researchers in rehabilitation engineering and assistive robotics, offering a systematic method to design more intuitive, responsive prosthetic devices. Sahoo’s contributions continue to inform the development of lightweight, tendon-driven hands that prioritize both functionality and user comfort.
