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...

Sheath-Core Fibers for Superelastic Electronics, Sensors, and Muscles

Summary:From fitness trackers to smart clothing, wearables are in high demand. Researchers at UT Dallas have invented a new class of elastic wires that can be woven into clothing or made into super-stretchy charger cords. Lighter-than-air, electrically conductive sheets of tiny carbon nanotubes are wrapped around a long rubber core to create conducting...

High Torque Density Switched Reluctance Motors

Applications like aerospace, automotive and robotics require high torque to volume/weight ratio machines. Permanent Magnet Machines have been considered to be the sole candidates, however, the limitation of the operational temperature, relatively high price, and unstable overseas supply of permanent magnet material limits its massive applications. There...

Unified Lower-Limb Prosthetic Control Strategy

Non-Confidential Description: This technology defines a novel control strategy for a powered prosthetic leg that unifies the entire gait cycle, eliminating the need to switch between controllers during different periods of gait. Current control methods divide the gait cycle into several sequential periods with independent controllers, resulting...

Fuel-Powered Artificial Muscles

These inventions are new, highly-efficient actuators which can function as artificial muscles. They are 100 times stronger than natural muscles, able to do 100 times greater work per cycle, and produce larger contractions than natural muscles. Developed using nanotechnology, these actuators are powered through two methods that convert the chemical energy...
