UNT College of Engineering professor Wonbong Choi and associate professor Gayatri Mehta are developing a sensor system for use in rebuilding and balancing the human knee, funded by a $150,000 grant from the National Science Foundation.

"Currently, surgeons tend to rely on their best judgment in determining what 'feels' like a balanced and stable knee," says Choi, who is part of the materials science and engineering department. "Dr. Mehta and I believe we can create a flexible, internal wireless sensor system that will measure interactions between the tibia and femur and provide doctors with real-time information on joint pressure distribution both during and after surgery."
