About

Karthik G. Murthy is a leading researcher at the intersection of biomedical engineering and human-machine interaction, with a primary focus on non-invasive sensing for prosthetic control and rehabilitation robotics. His most influential work, "Real-Time Classification of Hand Motions Using Ultrasound Imaging of Forearm Muscles" (2015), has garnered 159 citations and represents a paradigm shift in myoelectric control. While surface electromyography (sEMG) had long been the gold standard for sensing electrical muscle activity, Murthy pioneered the use of ultrasound imaging to capture mechanical deformations of functional forearm muscles in real time. This innovative approach offers superior spatial resolution and robustness against signal degradation caused by sweat, electrode shift, or fatigue. By demonstrating that ultrasound can classify complex hand motions with high accuracy, his work opened a new avenue for more intuitive and reliable muscle-computer interfaces. Murthy’s contributions have directly impacted the design of advanced prostheses and rehabilitation robots, providing amputees and stroke survivors with more natural control. His research continues to bridge the gap between clinical rehabilitation and cutting-edge sensor technology, establishing him as a key figure in the evolution of non-invasive neural interfaces.
