Total Energy Shaping for Task-Invariant Control of Lower-Limb Exoskeletons

We present a total energy shaping control methodology for the development of portable lower-limb assistive exoskeletons and orthotic devices that help reduce the human’s effort and augment natural motion. Current robotic exoskeletons restrict joint motion to pre-defined position trajectories during gait rehabilitation; such methods aim to replicate...

A Lower Limb Powered Orthosis for Improved Rehabilitation Training

Physical training is often needed for patients to relearn how to walk after a stroke, or other neurological damage. However, the frequency and availability of physical training are limited by finite medical resources: most lower-limb rehabilitation orthoses are stationary and only available in a limited number of clinical settings, due to their large...

Virtual Body-Weight Support via Lower-Limb Exoskeleton

Summary:This is a novel control system for powered lower-limb exoskeletons (or orthoses) that provides body-weight support (BWS) for people who have sustained a stroke and other neurological injury. Patients are provided with BWS during conventional gait retraining to help them produce the coordinated muscle activities needed for walking. Although current...

Neurocase: Peripheral Nerve Electrode for Neural Recording and Stimulation

The ability to record and stimulate neural activity with implanted microelectrode arrays has been limited by the problems of insertion trauma and foreign body response, which can lead to neuron damage and reduced reliability of results. Minimizing such tissue responses is necessary to develop implantable interfaces for studying neural activity and even...

Powered Prosthetic Leg for Restoring Natural Locomotion and Mobility Across Tasks

Current passive prostheses are used to alleviate the effects of amputation, but they are limited in their ability to completely restore functionality because such mechanisms may only dissipate energy that the user introduces. In the case of above-knee amputees, many passive prosthetic devices aim to mimic normal walking conditions but typically leave...

Entering the Fourth Dimension - Manufacturing Responsive Liquid Crystal Elastomer Structures

The University of Texas at Dallas is seeking companies interested in commercializing an innovative method for fabricating Liquid Crystal Elastomer (LCE) structures that undergo reversible actuation in a wide variety of environments. This method uses direct-write additive manufacturing to locally-control the molecular orientation of LCEs, thereby programming...

Improved Dental Abutment Geometries for Cement-Retained Crowns

According to the American Academy of Implant Dentistry, over 500,000 dental implants are performed per year in the United States. Despite being such a common procedure, peri-implant disease has been found to affect as much as 48% of implants according to the American Academy of Periodontology. Inefficiencies of commercial dental implant systems have...
