Final Project Presentation Video Made
We finally made a demo video of our product. I edited the videos and uploaded it to youtube.

Final Project Design Tasks
Now that we are in the last week of classes, we need to buckle down and figure out how to demonstrate our final design. The major change/addition we will have for the final presentation is the microneedle array. We have decided that the best way to demonstrate the needles would be through 3D printing or laser cutting a design where the needles are bigger (not necessarily on the micro-scale) just to get our point across. After all, we just need to demonstrate that our application device will shoot the needles into something (such as cooked chicken, styrofoam, or playdoh - something that would mimic the skin). This task will be hashed out in group meetings between this and next week, before our presentation on Friday, May 9th. Our allergy test device design has come a long way from the beginning of the semester and we can't wait to show everyone how it will physically work (even if it is scaled up to get the proof of concept across).

The future
With our design review due so soon and the graduation approaching, I can't help reflect on the information Jason presented on this week.
He gave us important information on how and where to look for jobs and how to network in the biotech area around us. As a senior graduating in May the word "future" and "job" seem scarier everyday. It felt nice to have help from someone going through the same thing. While the worry of finding a job is constant right now, knowing that not having a job by the summer isn't bad, makes me feel better.

I am in charge of describing the Pugh chart and how we chose our ideas.

Projector out of card box?
Yeah, no joke. I just learned that you can make a projector out of card box and a lens.
In this prototyping session, we were given some lenses, tapes, clips , crayons and a card box to make a projector. While the first idea that came to my mind was, "What?", Google told me that it's possible.
We covered all the gaps on the edges of the box, and proceeded to cut a hole that was about the shape of a given lens. The lens was then fitted into the hole. Once the phone was placed inside the box and the phone was set to have the most brightless, Voila! we couldn't see a thing.
The trick was to turn off the light. Once we did that, blurry image started to show up. Then, we adjusted the position of the phone, and also added a funnel using tape so that the air can be scattered through the lens. Overall, the projector came out pretty successful (I think).

Feedback from Design Review 3
With the approaching deadlines of senior design projects and interviews, I have had a very busy work schedule the past two weeks. Therefore, I will combine last week's blog post with this week's post below:
Last Week (week of April 7th):
After our presentation for design review 3, we were able to get good feedback on our prototype design. Most of the comments stated how our device seemed to be close to the final product, with great works like mechanisms. One recurring comment involved how the coating of the microneedles would work and how we can possibly color code the matrix, so the allergen locations can be seen. After all, what is the point of the test if the doctor doesn't know which allergen caused any reaction? These two issues will be address in design review four and in our final report and presentation.
This week:
On Friday, we are meeting as a group to discuss the final stages of our project and how to address the remaining issues from design review 3. We will finalize our design and make sure every aspect of our design has solved all of the problems we set out to improve upon at the beginning of the semester. We will also make sure we are concise with all the aspects of the presentation, since so much has to be fit in to a 10 minute presentation.

Close to Final Prototype Pictures
We have introduced two new improvements to our prototype for Design Review 3:
1) In the previous design reviews, our allergy stamp adopts a pressing mechanism. The doctor would place the allergy stamp onto the skin surface and then press down to apply the allergens. One of our classmate, Ian, had expressed a concern that the skin surface might bend in when the micro needles went down too slowly. We decided to adopt the pull and shoot mechanism, where the doctor would pull the micro needles and release to shoot them into the skin. The damping ratio as well as the spring constant must calibrated so that the spring would not bounce up and down on the skin.
2) Since the unused position of the inner plunger is in the downward position, so we also introduced a bottom cover so that the stamp can stay clean when not used.
