Project Introduction
An estimated 10,000 deaths occur annually due to heat related injuries for high school football players in the United States. In a collaboration with the Duke Big Ideas Lab, my team and I attempted to design a Heart Rate and sensing device to reside in a football pad as part of a larger internal temperature sensing system.
Report
The final report includes detailed descriptions of the design process and well as verification and validation for the final product. There are functional decompositions, detailed needs and specifications, sub-function descriptions (accelerometer, PPG, bluetooth, enclosure, battery life), testing results, proof of concept/principle, FMEA, LBM, and ethical considerations.
Wearable Bicep PPG
Supplement internal temperature sensing algorithm with photoplethysmography (PPG) motivated heart rate stream.

Contributions & Outcomes
I headed the efforts to develop firmware for an Adafruit Feather Sense to calculate heart Rate from a Photoplethysmography (PPG) data stream. Ths required creating the appropriate A2D circuit with filtering and amplification. Additional filtering was performed during post-processing. Additionally, I developed software to communicate the data from the onboard device to an ios application with the BLE 5.0 protocol.
