As a summer intern in the Medical Devices Group at MSR in 2016 I developed a fully-analog wearable passive sensor for continuous physiological monitoring. I returned to work with the group in late 2017 to work on further integration of the system to an existing sensor framework and to validate it with testing. The vision for this work is to develop a bandaid-like device that can be worn on the body for bed-side monitoring of heart rate, breathing rate or temperature. The device was also designed for sensor input flexibility as a plug-and-play platform that interfaces with different types of sensors. The prototype device performs sensing and communicates sensed signals at sub 200 micro Watts power budget (harvested from a 915MHz radio frequency continuous wave singal).
