This week in biomed my team and I focused on the construction and development of our product prototype. We discussed customer needs and materials to use, as well as how we are going to make the prototype.
The material we are using is similar to that of a “Dri-FIT” material. We chose this because it has the desired stretch, compression, and ventilation that we want in our product. “Dri-FIT” is used mostly for shirts or shorts by Nike in their athletic wear. This material is particularly helpful in reducing sweat and increased cooling while active. The only concern with this material is possible chafing and rubbing in the crease of the elbow. We are planning on solving this problem with a hole in the sleeve where the elbow is, to help prevent this discomfort.

Another element of our design that we evaluated this week was the elbow padding for impact reduction and support. We are looking into a NU-Foam pad insert that can be put in and removed from a pocket on the elbow of our sleeve. This particular material is mildew resistant, beneficial due to sweat, and does not disintegrate over time like most padding. The only obstacle with this material is that it compresses over time, creating a less thick boundary. This can be solved through selling insert replacements for the sleeve.
This week we have been able to advance our prototype by beginning to actually sew it together, increasing the functionality and accuracy of the prototype. In order to do this, 3 of our 4 team members, including myself, were trained in how to use a sewing machine. This process was simple enough, and is now a very valuable asset to the improvement of our prototype. We have begun by sewing the pocket for the foam insert, and plan to sew the sleeve together next class.
