Semester 2 Week 6 - Brinkley

 This week I contributed to del. 6, manufacturing the model, and testing the pressure in the model with the sutures. 


I was given the system section for Del. 6, so I wrote out how the tubes connect to the housing, the gluing process, and how we insert the sutures into the tubes as resistors. 

During capstone we created more valves to test on. We have finally gotten the size down to what it should be, and we had 3/4 working valves, which shows that our method is pretty consistent compared to what we used to get. 


This is 1 of the 3 working valves with the sutures coated in super glue.


This was the epoxy we used to coat our suture




In the lab this week I was heavily working on getting the right sutures. We tried to coat the sutures in super glue 1,2,&3 times to see if that would better block our tube and help vary resistance. The data from this is pretty wonky, so we are no longer going to be using this method. Instead we tried dipping the suture in hard epoxy to waterproof it and make it slightly thicker. This created too great of a resistance and allowed no flow, so we will be thinking of a new method this week/finding different sized sutures.

Week 9 - Brinkley

 This week was a lot of testing and research. I am still working on the dissolving component and figure out that data, which will make more sense with time hopefully. When we were in the capstone block, we did a couple of shakedowns, we did a brief resistor in parallel test that worked great, Fady set up the sensors, and we modified parts we already had to make them work for shakedowns.  The research I did this week was about materials. I researched silicone sheets, silicone molding, glue, and sutures. For each category I found biocompatible and regular options. The regular options are much cheaper and easier to get.  Here are the links to the products I found:  Research Mold and Curing Silicone:  Biocompatible: https://www.elkem.com/silicones/offer/healthcare/medical-grade/liquid-silicone-rubber/ I would suggest soft or mid durometer because it would be less preventative of the tube expanding. Less resistance. Another option is:  https://products-silicones...
