Real-Time Measurements From Wearable Sensors To Enhance Stability On Uneven Terrain, Sophie Copelin
Real-Time Measurements From Wearable Sensors To Enhance Stability On Uneven Terrain, Sophie Copelin
Biomedical Engineering Undergraduate Honors Theses
The presented thesis is a study of sensation associated with inversion/eversion movement about the anterior/posterior axis. The long-term goal is to create a system that provides feedback to a prosthesis user, so their chances of falling is decreased. This feedback system would use wearable sensors to detect certain angles, so that sensory feedback could be provided. The study aimed to determine if Xsens Movella DOT sensors could be used in a system like this, so the accuracy of the Xsens Movella DOT sensors was assessed and the difference in angles that could be determined by them when compared to that …
The Effects Of Microgravity On Human Endothelial Cells In Relation To Deep Vein Thrombosis, Allie Burgess
The Effects Of Microgravity On Human Endothelial Cells In Relation To Deep Vein Thrombosis, Allie Burgess
Biomedical Engineering Undergraduate Honors Theses
Deep vein thrombosis (DVT) is a condition where blood clots form in one or more of the deep veins of the body, causing leg pain and/or swelling, potentially leading to pulmonary embolism and/or stroke. The incidence of DVT among astronauts serving on the International Space Station has been shown to be greater than that of the general population, calling into question the effects of microgravity on human thrombolytic processes. Additionally, microgravity conditions have been shown to cause muscular atrophy and a decrease in muscle strength and mobility. Because collagen composes a large portion of muscle tissue, this study also assessed …
3d Printed Force Transducers For In-Vitro Mitral Valve Chordae Tendineae Force Measurements, Hayley Chandler
3d Printed Force Transducers For In-Vitro Mitral Valve Chordae Tendineae Force Measurements, Hayley Chandler
Biomedical Engineering Undergraduate Honors Theses
Mitral valve surgery is incredibly prevalent in the United States with more than 40,000 mitral valve surgical procedures annually. Improving the imaging techniques used to diagnose these cases requires validation of 3D models through experimental data such as mechanical properties of the tissue. An essential part of this process for the mitral valve is measuring the force experienced by chordae tendineae. This has been achieved with brass force transducers but using a 3D printed design can have many benefits. In this study, 3D printed miniature c-shaped force transducers comparable to previous metal models were designed and created using Solidworks 2016. …
Pressure Acquisition System For In Vitro Mitral Valve Analysis, Laura Peck
Pressure Acquisition System For In Vitro Mitral Valve Analysis, Laura Peck
Biomedical Engineering Undergraduate Honors Theses
In vitro testing of the mitral valve chordae tendineae is utilized to aid in the understanding of the stresses that occur in vivo and improve upon surgical solutions that exist for mitral valve repair. This project aimed to design the water control system for a left heart simulation chamber, as well as the pressure acquisition inside the chamber. A solenoid valve was utilized to control the water supply to the tank and was powered utilizing National Instruments software. National Instruments hardware and software was also used with the pressure transducer in order to obtain pressure readings from the chamber. The …
