This week we finished up validation testing of our device, as well as fully assembled our device. We also focused on writing our final paper, which is due at noon today. All we have left to do for Senior Design is to make our presentation for next Wednesday and our poster for BME Day.
April 13, 2018
This week we have been really busy. Some parts we ordered finally came in and we completed our circuit. We used our circuit to take measurements on the tofu, both with wires and surface electrodes. We also connected our Arduino to our circuit pump as the function generator.
April 6, 2018
This week we continued to work on our circuit. We ordered some additional parts that are anticipated to arrive by next Tuesday. We also worked on programming the Arduino to output an oscillating signal. Finally, we did research on and worked with surface electrodes.
March 30, 2018
This week we analyzed our circuit data. We also received our verification and validation paper comments and we are looking into incorporating the feedback.
March 23, 2018
This week we regrouped after spring break to schedule our next steps. We collected additional data from our circuit and planned our phantom experiments with tofu.

This week we focused on writing our Validation and Verification paper that is also due today.
February 23, 2018
This week we have built our circuit to measure bio-impedance. We are currently testing the circuit to make sure the measurements are correct.
February 16, 2018
This week we decided that using the Arduino and Raspberry Pi in conjunction will be our best option. We need the Arduino so we can use the signal generator shield which will be connected to the stimulating electrodes. The Pi will be the main processor. Matthew and Melinda will meet with Dr. Moran next week to learn more about how we should orient the electrodes.
February 9, 2018
This week, we further narrowed down the choice of methods used to measure bioimpedance and looked up ideas for building circuits for our purposes.
February 2, 2018
Now that Matthew is feeling better from the flu we have begun the prototyping process! We are looking into the best deals for the parts we need and soon we will begin ordering them.
January 26, 2018
Our budget was approved over winter break, and we are beginning the prototyping process. First, we have divided up the project into three main components: the user interface, bioimpedance measurements, and biological validation. While we will work together to prototype the device, each person will spearhead one of these components:
User interface: Melinda
Bioimpedance measurements: Matthew
Biological validation: Emily
We have not been able to meet in person yet, as Matthew has the flu.
December 1, 2017
After researching multiple alternative solutions for measuring fluid content, our team has decided that we will pursue the design that involves bioimpedance measurements. Our Pugh Chart showing our analysis is in the appendix of our progress report (due today). The device will likely be Arduino-based, and our next step is to work on the circuitry required to amplify the measurements.

This week we continued to research existing technologies that may have applications for our project, continuing to focus on devices that are not currently related to edema. We have also continued our brainstorm process.
October 27, 2017
This week, we found other existing technologies that relate to size measurements of tissues, and we will further evaluate their potential for measuring peripheral edema. We have also created our team website (linked below), and we will implement a few updates.

This week we received feedback on our preliminary report as well as Melinda’s preliminary presentation from Professor Yin and Kristina. Based on our feedback we began to look at existing technologies that are not specifically edema measuring devices, and we will continue to research as we brainstorm for our project. We have also begun work on our website, which will be fully functional by Monday. When complete, we will send a link to Dr. Hammill.
October 6, 2017
We met with Dr. Hammill earlier this week to review specifications and metrics. We have incorporated these into our preliminary report. In writing this first report, we all contributed to researching current solutions for monitoring edema and found patents for various devices. We found that there are very few solutions that the patient can use independently, and this is a main component of our project.
September 29, 2017
We have revised our project scope and plan to review it in more detail with our client. We also want to determine the importance of each specification (ease of use, cost, size, frequency of measurements, etc). There will be a team meeting this weekend to brainstorm designs and begin drafting our first paper.
