The natural environment poses a significant number of obstacles and dynamic settings that makes mobility difficult for those with physical and mobility impairments. To approach this problem, a suspension was designed using inspiration from the early Mars rovers developed by NASA for traversing the varied Martian landscape. The course of the project followed the direction of a start-up through problem identification, early design generation and review, and final design production. The project outcome, through client request and proven market research, aimed to produce a multi-terrain wheelchair. The final product is a kinematic body with mobile front “legs” and a rotational …
Effects Of Micro-Features On Cell Detachment From Poly(N-Isopropylacrylamide) Coated Polydimethylsiloxane Membranes, Luke Webel
Williams Honors College, Honors Research Projects
The tested hypothesis was that features on polydimethylsiloxane (PDMS) surfaces coated with a poly(N-isopropylacrylamide)/aminopropyltriethoxysilane or pNIPAAM/APTES thin film would accelerate cell detachment than the film coated on a unfeatured surface. This project tested samples with features generated by molds, wrinkling, and sandpaper roughened substrates. Surface feature generation methods were limited to mechanical means, and characterized by microscopy and strain rates. 50/50 mixtures of 1.5 wt.% pNIPAAM/ APTES were used to coat thin films (30-40 nm) on PDMS membranes by spin-coating, and the coated membranes were thermally annealed to chemically graft pNIPAAm/APTES on the membrane and their thermo-responsive property was assessed …

Medical endoscopy is a growing industry, with a trend of chronic hand pain for gastroenterologists and flexible endoscope users. In order to address the lack of ergonomics in traditional gastrointestinal (GI) flexible endoscopes, the design team collaborated with a GI professional to design a more ergonomic endoscope interface, focusing on the more problematic controls. Two prototypes, as well as a mock-up were fabricated, which underwent verification and a user evaluation to assess the design’s benefits. As the number of endoscopies each year increase, the Ergoscope, offers an alternative to the traditional angulation controls and muchneeded relief for the issues that …

We set out in August 2017 to develop an active noise suppressing device that would be usable both in military and civilian activities. Due to constraints in knowledge and time, we decided our best course of action was to divide the project into two equal projects with the hope to be able to combine them into a single project at the end of the allotted time. This consisted of an active noise suppression device and a passive noise suppression device. The passive device would have no electronic components and the active device would be pure circuitry with no housing. This …
