About

A. K. Prasitha Sathsara is a researcher specializing in biomechatronics and robotic prosthetics, with a focus on developing innovative, energy-efficient solutions for lower-limb assistive devices. Her key research areas include hybrid actuation mechanisms, passive-adaptive systems, and the design of transtibial robotic prostheses. Sathsara’s major contribution is the proposal of a hybrid powering mechanism for a unilateral transtibial robotic prosthesis named TRoPHy, which integrates both active and passive actuation methods for plantar flexion and dorsiflexion, while allowing passive inversion and eversion. This design leverages separate spring systems to reduce energy consumption and improve natural gait dynamics. Although her most-cited paper has garnered 4 citations, its impact lies in its foundational approach to combining active and passive elements, offering a scalable framework for future prosthetic innovations. Sathsara’s work is notable for addressing the critical challenge of balancing power efficiency with biomimetic functionality, making her a promising voice in the field of assistive robotics. Her research holds potential to enhance mobility and quality of life for individuals with lower-limb amputations.
