Project Updates

September

  • Design inputs were presented to peers and faculty advisors for feedback, then refined based on their suggestions.
  • The team developed relevant project constraints and addressed any new device requirements that emerged as a result.

October

  • The team identified applicable standards for the project and created a Gantt chart outlining the task completion timeline.
  • A preliminary budget was finalized for ordering project components, including electronics, materials, reagents, and miscellaneous supplies.
  • Flowcharts were created to map out the device’s functionality from both the user’s perspective and its internal processes, helping to streamline overall operation.
  • The team has entered the initial phase of developing potential design concepts for the project.
  • Specifications and verification activities for the design inputs were determined.
  • The team presented their interim design presentation and received feedback from peers and faculty.

November

  • A hazard analysis was conducted to address any risk associated with the project.
  • The team is making final decisions on project components so that parts can be ordered and manufacturing can begin.
  • The team finalized the abstract for the project.
  • Revisions were made to design inputs for the final design presentation of the Fall 2024 semester.
  • The treasurer began to order materials and device components.

December

  • The team presented their final design review for the semester!

January

  • Manufacturing of the device has begun, including microfluidics and peristaltic pump control via microcontroller.
  • The team is actively writing and revising verification and validation protocols for the device.

February

  • Sara has begun running the protocols for leukocyte and nitrite reactions.
  • Jon has sent the mold for the urine collection cup for 3D printing, and is finalizing the CAD model of the control box.
  • Erin is working on the microfluidics of the urine transport from the urine collection cup to the control box, and how to split the sample for urinalysis.
  • Iman is testing the colorimetric sensors for urinalysis as well as the load cells for volume readings within the control box.

March

  • Jon 3D printed the urine collection cup out of Agilus material with a shore hardness of 30A for proof of concept.
  • Sara worked on the Nitrite reagent testing and developing calibration curves.
  • Jon created the CAD model of the control box as well as the press fit mold for the urine collection cup.
  • Iman calibrated the colorimetric sensor to run verification tests with Sara’s Nitrite reactions and achieved 20/20 accurate detections.
  • Iman and Erin are actively working to finalize the urine sample transport throughout the control box through the manipulation of peristaltic pumps.
  • Iman has finalized the initial detection of the urination cycle using a thermistor in the urine collection cup.
  • The team was also lucky enough to present their progress so far at NEBEC 2025 hosted by NYU Tandon School of Engineering!
