Wow, this past week has definitely been eventful for Team Heartache. On Thursday of Week 3, we had the opportunity to have our prototype evaluated by Dr. Matthew Wettergreen. He pointed out the importance the building our following prototypes in saline since out device will be submersible in the liquid (Points out the spaghetti noodle-marshmallow challenge from ENGI 120). We had our mid-summer presentation on the Friday of the same week and our second client meeting. Our clients did find the tracking system for the lung system promising but wanted a vertical motion of the heart contraction instead of the rocking motion our prototypes had. In this way, our device creates a sine in a sine wave motion for the tissue they will test with

During the beginning of the following week, our team split off with Chris and I exploring the possibility of using an additional spring board and an iron solenoid coil to create the heart contraction motion while Rachel and Kaitlyn worked using the sole tissue table to create the combine sine wave. Rachel was able to design a structure where the tissue table is built with a concentric tube and a notch that will lock on to the inner tube it will run along. Pictures are shown below
