Smart watches contain a wealth of sensors with the potential to transform health research and intervention, but few teams have the the technical skills to use these devices. 

Biodata is a smartwatch app which can simplify acquiring health data, based on our lessons learned building the SleepStim system. Biodata transforms a Wear OS smartwatch into a reliable, configurable data acquisition device for research. Because smartwatches are easily worn by participants, it can be used for a wide range of research tasks including

* Characterizing sleep and activity patterns

* Detecting abnormalities like tremor or irregular heart rate

* Tracking emotional and physiological states

* Measuring changes in behavior when participants receive an intervention

* Real-time biofeedback

Biodata is an early-stage project which we hope will open up new possibilities for health research. You can follow the project at
