Build & Test Prep
Table of Contents
Team Vision for Build & Test Prep PhaseThis phase was largely dedicated to designing the electrical system for the device. The CAD models for the device were finalized so that a prototype model could be 3-D printed and assembled.
Test Plan Summary
TABLE 1:Updated Test Plan List (click link to view test plan outline)
|Test Plan #||Engineering Requirement||Title||Purpose|

|3||15, 16||Autoclave Testing||Determine if selected materials for mechanical strain applicator can withstand autoclave conditions.|
|4||3||Material Testing||Tensile Testing using ASTM standard D638.|
|5||5,9,13,14||Ease of Use||Assembly/Disassembly, Protocol, Intuitive Software, etc.|
|6||10,14,19,20||Chamber Design Test||Ensure chamber growth surface area is sufficient for cell growth and viewable with microscope. Chamber height compatible with microscope.|
|7||9||Software and Device Motion Testing||Verify that software performance is acceptable and it is producing desired outputs.|
|8||22||Cost||Determine whether project development costs are fully funded by allocated MSD funds.|
|9||23,24||Longevity Testing||Determine whether the device will withstand multiple uses (equal to five years with ten uses per year).|
|10||11||Heat Cure Testing||Determine whether different heat cure conditions affect the material properties of PDMS.|
|11||11||Cellular Response to Strain||Determine the effects of different strain % and frequency of strain on the cell culture formation.|
