Innovative, patient minded, & life saving design
Phase 01 has been the most critical phase in SOX's lifespan thus far. After much research and consideration, we invented a product that will save lives and that we full-heartedly believe in. This means that at this time, our phase 02 and phase 03 are in an iterative process as we continue to perfect our product. It will not be until the final iteration that we will be proud to present SOX for everyday use to achieve augMEDted's goal of improving lives.
PHASE 01
Needs Assessment & Ideation
Our bioengineer's vast clinical background combined with an engineering mindset is what made all the difference here. It required utilizing our knowledge of what medical problems exist but more specifically finding those which can be solved or improved through the use of sensors. After many iterations, we were pleased to decide on two needs that could be met with one simple wearable device.
STEP 01 | ASSESSMENT
Research
Presentation
Final Proposal
This step looked like individual research for needs assessment
Presenting our idea with very thorough and realistic steps needed to achieve the solution
Pros and cons of each to find the best idea
PHASE 02
Fabrication
This phase involved evaluating which biological signals were most important for early detection of DVT and thus which sensors were required. As well as determining how we would measure the center of gravity to provide intuitive feedback to the user for the prevention of falls. As we considered all of these factors we always kept our dedication to the user and high-quality fashion in the foreground.
STEP 01 | DESIGN
Vision
Finalization of which sensors were needed and planning sensor location placement to achieve the SOX requirements.
Sketches
Detailed sketches outlining exactly where the sensors are to be sewn for accurate measurement of the biological signals of interest.
STEP 02 | PARTS
Finalizing sensors
Low-cost wearable sensors were chosen to be integrated into the sock. These included a thermistor, PPG, force sensors, resistive fabric, and haptic motors.
Ordering parts
Parts were ordered from SparkFun and Adafruit. Individual sensor device specifications can be found in the user-manual located on the support page.
PCB
Autodesk Eagle was used to design and print a custom PCB for all of SOX's components.
STEP 03 | ASSEMBLY
Sewing
Carefully hand-sewn stitches with high attention to detail for maximum comfort and accuracy.
Housing
3D rendering and printing of housing for the Arduino Firebeetle, PCB, and battery achieved through SolidWorks and Dremel 3D printer.
Prototype
The sock, hardware housing, and sewn-on sensors produced a prototype ready for testing.
PHASE 03
Testing hardware & software
The assembled prototype from the previous stage was tested sensor by sensor to ensure the SOX's accuracy. Upon confirming each worked properly, threshold values were set for healthy and DVT cases for early detection.
STEP 01 | VALIDATION
Healthy thresholds were established in Arduino
DVT thresholds set according to clinical data
User Interface developed in Processing for simple and easy use
STEP 02 | ADJUSTMENTS
Small troubleshooting errors were done with the PCB and code
Additional code has been written to adjust the healthy threshold to each individual wearer
STEP 03 | SOX
AugMEDted is pleased and proud to present a working prototype that is ready for the next stage.
SOX will help prevent falls, but send alerts to an emergency contact if one does happen. SOX will detect if there are symptoms of DVT present and alert your doctor.
