Towards Low-Power, Timing-Predictable Medical Monitoring
Overview
In my first semester at ETH Zürich, I developed a Medical Monitoring Device as my first semester project. The full report can be downloaded below.
Major features:
- TI MSP432 ARM Cortex-M4F core microcontroller
- Nonin OEM III pulse oximetry sensor
- BOLT stateful processor interconnect
- FreeRTOS
- Timing predictability for bounded response times
- Low-power system design
- Extensive timing analysis
- Detailed power analysis
Abstract
This semester thesis describes the design and implementation of a prototype medical monitoring device. The device can measure human vital signs, such as heart rate and blood oxygen saturation. The measured data is forwarded to a connected device (e.g. PC, smartphone, etc.), moreover received control commands are also interpreted and processed by the device. The two key design goals of the medical device design are timing predictability and low power dissipation. Timing predictability is motivated by the need to provide response and alerts within guaranteed time bounds. Low power dissipation facilitate the portability and mobility of the device. This thesis describes the design and development of the system and its operation in details, and presents the results of the performed timing and power analysis. The final conclusion summarizes the project and my experience, moreover it contains my personal ideas and opinions, as well as an envisioned proposal as a possible future work.
