Continuous heart rate monitors (CHRM) can give unique insights into a person's physiological and psychological state; however, existing CHRMs are not suitable for continuous monitoring because they do not provide beat-to-beat accuracy and comfort needed for all-day use. Our group is currently developing a miniature earlobe mounted CHRM system which is both comfortable and provides beat-to-beat accuracy, based on a miniature heart rate sensing technology developed previously in our lab. The objective of this thesis is to design low power system firmware to perform key tasks: i) acquire heart rate and skin temperature data from wearable sensors; ii) signal process the raw heart rate data to calculate r-r interval; iii) optimize the heart rate sensor parameters for power and noise; iv) store the sensor data in local flash memory, and v) stream the data to an Android device. Each of the above functions was successfully implemented with low power considerations
