Preliminary Designs

After attempting to do a sequence drawing schematic of how our device would be used during class, we all decided that we need to have a clear understanding of how our device functions. We also need to figure out whether or not we will use biodegradable microneedles, whether we will inject the allergen through these microneedles, or whether we will just coat the microneedles with the allergen. We also have to figure out the most common allergies we should test for using this stamp.

According to this Mother Nature Network article, the 9 most common allergies are the following:

1. Wheat

2. Penicillin

3. Eggs

4. Pet Dander (for cats and dogs)

5. Mold

6. Milk

7. Pollen

8. Peanuts

9. Sun

Obviously, we won't be able to test for some of these allergies, such as milk, by using a test like ours, but this list is a start. As an example, our device could have a matrix containing 8 allergens and 1 control. Below are some preliminary designs I have created on the basic shape of the stamper and allergen matrix.
