Independent Study: Ultra-Low Power Pressure Ulcer Prevention System

WPI, August 2017 – May 2018

Advisor: Professor John McNeill, Dean of Engineering

  • Developed a time-based resistance measurement algorithm with error analysis, simulation and verification to save more power and increase the accuracy for the resistive-force sensor system
  • Modeled non-idealities due to the creep behavior of piezoresistance for the conductor-filled polymer composites
  • Calibrated resistive-force sensor using MATLAB to bring down the measurement error from 10% to 2%

Major Qualifying Project (Senior Thesis)

WPI, September 2017 – May 2018

Advisor: Professor Reinhold Ludwig, Professor and Department Head

  • Developed a small, accurate, and efficient integrated circuits capable of measuring a variety of vital parameters to create an innovative wearable health monitor on a team of three.
  • Proposed features to monitor the user’s heartbeat, blood pressure, internal temperature, respiration rate, and galvanic skin response, as well as providing fall detection.
  • Worked on SPI Communication between microcontroller CC2650 and accelerometer ADXL362, using Code Composer Studio and Analog-to-Digital Converter inside the microcontroller to process ECG heart rate monitor AD8233 analog data.
