The tendency of snowboarders to fall with outstretched hands has led to a high number of wrist injuries. Commercial wrist guards are restrictive, bulky and transfer impact force from the wrist to the forearm and elbow. Consequently, many snowboarders do not wear wrist guards. The goal of this project was to increase use of wrist guards and decrease wrist fractures by creating a thin, non-restrictive design with superior impact absorption. The final prototype incorporated removable individual cells of a shear-thickening polymer in a protective glove liner. The flexible and slim design increased the comfort of the user. Drop weight impact testing demonstrated impact force absorption in a simulated fall of 61-68% within a temperature range of -4 to 68 degrees Fahrenheit.
