Overview of Status of Analysis, Design, Fabrication, Tests, etc.
We have purchased a micro-controller, smooth copper plated clips, and various amounts of circuitry to take voltage measurements.
CAD model of device handle completed.
Accomplishments from Previous Week
Impedance measurements of human tendons were conducted under known, varying forces.
Data curves were plotted. The plots show Voltage vs. Force.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Determine if impedance design is the method that this project will carry out.
While finalizing feasibility of impedance, continue working on strain gauge based devices as back-up plan.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
As of Friday, January 25th, 2013, Sponsor has indicated a strong interest in continuing the impedance measurements.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Write up procedure of what we did with all variables in the lab
Talk to Steve Roberts about using a resistor decade box
"Just get lots of Data"
Decide if impedance design is worth pursuing
Sponsor feels that impedance design is still viable, and would like us to continue to pursue it.
Risks and Areas of Concern
If a device that relates force to change in impedance of a tendon, will the be dissipated in the body?
How to generate an AC signal and measure that with a micro-controller.
Schedule
Have a prototype working by week 5 and finalize design decisions.
Take more data.
Budget (list amount spent and amount remaining)
We have not spent any from our sponsor budget yet. Any supplies we have, we have bought on our own. Receipts have been retained.
Progress on Report and Webpage
