Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Standardized measurement device prototype for measuring the cross-sectional area of tendons has been fabricated
Accomplishments from Previous Week
Tested Wheatstone bridge as an impedance measurement device for human tendons
Compiled data from that test.
G-machine completed.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Test Wheatstone bridge method under known loads
Test Strain gauge device under known loads
Both methods will be assessed with cross-sectional measurement device prototype
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Have a prototype for cross-sectional area ready for week 5.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Build a prototype for the cross-sectional measurement device.
A CAD model was built of the prototype, assemble by using the lasercamm and acrylic.
Research possible sensors for cross-sectional device. Pedro suggested Hal-effects sensors.
Looked into Hal-effects sensor, and found this sensor to be a viable option.
Looking into ordering one this week, and having it shipped ASAP
Risks and Areas of Concern
Precision of sensor for cross-sectional area device may give us the resolution we need.
Scheduling a meeting with sponsor has been difficult. Earliest we can meet is 2/20.
Schedule
Test Wheatstone bridge and strain gauge under known loads.
Complete requirements for report by Friday midnight
Budget (list amount spent and amount remaining)
$7000 remaining
Looking at purchasing a Hal-effects sensor this week, shouldn't be more than $30, including shipping and handling.
Progress on Report and Webpage
