MSMS Software Package

Rahman Davoodi, Ph.D.

Movement neural prostheses for paralyzed and amputee patients are complex systems that require sophisticated control strategies to operate effectively. To facilitate the systematic design of such control systems, we have developed sophisticated software tools known as MSMS that allow the user to develop accurate models of a neural prosthesis for paralyzed and amputee patients. These models can be used to simulate the movement of the neural prosthesis under various control strategies and external perturbations. We have also developed a virtual reality environment where the above models can be...

BioTac multimodal tactile sensors now commercialized by Syntouch LLC

Gerald Loeb, M.D., Jeremy Fishel, Gary Lin

The performance of robotic and prosthetic hands in unstructured environments is severely limited by their having little or no tactile information compared to the rich tactile feedback of the human hand. We have developed a novel, robust tactile sensor array that mimics the mechanical properties and distributed touch receptors of the human fingertip. It consists of a rigid core surrounded by a weakly conductive fluid contained within an elastomeric skin. The sensor uses the deformable properties of the finger pad as part of the transduction process.   Multiple electrodes are mounted on...

Spinal-Like Regulator

Jared Goodner, John Sunwoo

Most studies of arm and hand movements in primates have attempted to relate neural activity in motor cortex to simple features of the movement (e.g. position, force, individual muscle activity). But motor cortex does not control those features directly; it acts through the complex circuitry of the spinal cord and the mechanics of the musculoskeletal system. “The Circuitry of the Human Spinal Cord” has been well-described for simple antagonist pairs of muscles but it isn’t clear how it can be extended to multimuscle, multi-degree-of-freedom linkages. We have modeled a two-axis,...

Mini pacemaker for fetus with heart block

Adriana Nicholson, Li Zhou

Complete heart block in the fetus can be a life-threatening emergency with no effective treatment options beyond watchful waiting. Fetal bradycardia due to heart block can progress in utero, and for more than a quarter of these fetuses may result in hydrops fetalis.3,4  Once hydrops fetalis develops, if the fetus cannot be delivered due to prematurity or other clinical concerns, fetal demise is nearly inevitable. We have developed a novel micropacemaker to address the critical problem of complete heart block in the fetus.  This condition is a life-threatening emergency in a fetus, and is...
