What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I met with Iqui multiple times this week to fabricate 5 more soft cases made out of the liquid silicone. I was running into issues where a significant number of air bubbles would get trapped in the mold, resulting in holes in the liquid silicone after it cured.
I worked on fabricating a new mold for the case based on Dr. Halilaj’s feedback (rounded edges, slightly thicker) and have been working on trying different methods for the case to get rid of the large air bubbles.
I also discussed with Vu different options for the device adhesive. The wig tape I was intending on using did not stick to the soft silicone material well – it was easily peeled off and removed. As an alternative, I proposed using adhesive/tape used for attaching glucose monitors onto an individual’s arm instead of the wig tape we originally proposed. The glucose tape seemed to work well and stuck to the soft case.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
My progress is behind since the soft cases I have been fabricating are not ready yet for the device to be fully wearable. This weekend I am planning on making more soft cases such that the whole device can be taped onto the shank for testing.
I am also slightly behind with resoldering the MCU/mux component with the battery to take it off the breadboard since the parts we ordered went missing for a few days, however I found the parts so I will work on that early next week.
What deliverables do you hope to complete in the next week?
- Prepare for demo
- Resolder the MCU/multiplexer and attach the battery with the switch so that I can take the MCU off the breadboard
- Print a case for the MCU+mux+battery to make it fully wearable
- Make new versions of the soft case and find a way to remove bubbles from the silicone
- Make enough cases for both the left and right LRAs
- Write up experimental protocol for the user testing of the device
