Biodegradable And Biocompatible Silk Fibroin For Optical Applications, Corey Bryce Malinowski

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study presents nanopatterned silk fibroin films that were fabricated using soft lithography and nanoimprinting to replicate patterns from diffraction gratings. These film’s optics were analyzed based on their light scattering potential as well as their transmittance and transmission haze using a laser light, spectrometer, and UV-Vis spectrophotometer, respectively. The patterned fibroin films all displayed similar light scattering patterns to their master patterns with some transmission haze. When using the spectrometer to measure samples, those made without any nanostructure displayed transmission of 90% and over, while those with patterns depended on the structure used. The denser a structure, like the …

Enhancing Mobility And Independence Of Wheelchair Users, Briar Blake, Paul Nauleau

Interdisciplinary Design Senior Theses

Conditions as simple as a leg fracture or more severe impairments such as paralysis and stroke may confine a person to a wheelchair. Wheelchairs help people with limited mobility transport themselves to different locations, but do not help the person leave the wheelchair. Users would need to do this to enter a car, use the restroom, take a shower, and sit at a table comfortably with family. The following design is a wheelchair attachment that serves to provide the user with increased mobility and independence. Wheelchair users struggle to get into and out of their chairs due to the unassisted …

Powering A Biosensor Using Wearable Thermoelectric Technology, Anneliese Bals, Noah Barnes, Rafael Bravo, Nicolas Garcia, Joseph O'Bryan, Dylan Santana

Interdisciplinary Design Senior Theses

Wearable medical devices such as insulin pumps, glucose monitors, hearing aids, and electrocardiograms provide necessary medical aid and monitoring to millions of users worldwide. These battery powered devices require battery replacement and frequent charging that reduces the freedom and peace of mind of users. Additionally, the significant portion of the world without access to electricity is unable to use these medical devices as they have no means to power them constantly. Wearable thermoelectric power generation aims to charge these medical device batteries without a need for grid power.

Our team has developing a wristband prototype that uses body heat, ambient …
