System for Extracting Venous Pulsation and Respiratory Information from Photoplethysmographs

The University of Texas at Dallas presents a technique that addresses the inaccuracy of skin-mounted photoplethysmographic (PPG) biosensor measurements by separating the arterial and venous signals - enabling extraction of other medically-relevant features, including: respiration rate, heart rate, and SpO2. The effective removal of various motion artifacts...

Accurate and Motion-Tolerant Sensing of Arterial and Venous Pulsation for Wearable Photoplethysmographic (PPG) Biosensors

The University of Texas at Dallas presents a real-time, adaptive technique that provides robust signal enhancement against motion artifact for wearable photoplethysmographic (PPG) systems, enabling the reliable extraction of heart rate and oxygen saturation. Despite the benefits of using PPG biosensors, most of the useful information they capture...

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...

Amorphous Silicon Carbide Ultramicroelectrode Arrays for Neural Interfaces

The clinical ability to record and stimulate neural activity with implanted microelectrode arrays has been limited by the problems of insertion trauma and foreign body response (FBR), which can lead to neuron damage and reduced reliability. Minimizing this tissue response is necessary for the development of implantable interfaces for studying neural...

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...
