Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
Honors Projects
A 3D printed hand and arm prosthetic was created from the idea of adding bionic elements while keeping the cost low. It was designed based on existing models, desired functions, and materials available. A tilt sensor keeps the hand level, two motors move the wrist in two different directions, a limit switch signals the fingers to open and close, and another motor helps open and close the fingers. All sensors and motors were built on a circuit board, programmed using an Arduino, and powered by a battery. Other supporting materials include metal brackets, screws, guitar strings, elastic bands, small clamps, …

Methane Sensing In The Field, Kyle Robert Zigner
Senior Projects Spring 2019
Is renewable energy as beneficial to our environment as we think? The demand for renewable energy has drastically increased over the last century due to the overuse of most fossil fuels, but the possible side effects of these new forms of energy must be carefully considered. One particular case of interest is that of methane emission from reservoirs formed behind hydropower dams. Due to the anaerobic bacteria decomposition of plant matter under water, methane is emitted from these types of wetland areas. This research thesis aims to investigate the feasibility of remote-controlled methane sensing which would provide concentration data at …
