Synthesis of Thin Film Vanadium Oxide (VO2)
Introduction: This project involves refining a synthesis of thin films of solid state Vanadium Oxide (VO2) using sol-gel methods. By precisely controlling the processing conditions, (baking temperature, ambient gas in the oven, baking time, solvent etc.), VO2 films can be synthesized that are highly resistant to oxidation. Current published methods...

A Magneto-Rheological-Based Actuation System
Background: With current means of actuation, very few options exist that provide multiple degrees of freedom (DOF) and move independently without the addition of multiple motors. For instance, conventional means of safely actuating robotic devices involve the use of specially modified servo motors at each joint to control motion. In most applicatio...
