Don’t throw away data!
3 KHz accelerometry on the chest can capture Coughing, sneezing, snoring, speaking, more…
Full-rate ECG can capture Stress levels, activity levels, more…
Audio during sleep can capture Snoring, reasons for awakening, more…

Big Data
12 KSPS x 1 day = 1 billion samples per day Not a job for MySQL
BodyTrack Datastore supports rapid access across levels of detail (GigaPan)BodyTrack Viewer allows rapid exploration of billions of datapoints
Easy to add real-time computation to combine data and generate new metrics

Family of open source sensors sharing a common technology base XMEGA processor, log data to SDHC, interface to host over FTDI USB Firmware supporting both current designs at https://github.com/BodyTrack/BodyTrack_CustomLoggers Java gateway code at https://github.com/BodyTrack/bodytrack-logger-gateway
Microclimate Environmental Basestation (Hardware; firmware in C) Hardware design at https://github.com/BodyTrack/Schematic_BaseStation Version 3 currently in alpha test; approaching beta-quality. Directly measures temperature, humidity, barometric pressure, sound and light levels Interfaces to Dylos air particulate monitors over serial Supports introspection on sleep hygiene, circadian rhythm, respiratory stressors, etc.
Chest Strap Hardware design at https://github.com/BodyTrack/Schematic_ChestStrap Directly measures EKG, respiration, accelerometry, temperature, and humidity Supports work on derived metrics for stress (HRV), coughing, sneezing, snoring, etc.

Open-Source Sensor Projects

BodyTrack: Open Source Tools for Health Empowerment through Self-Tracking
BodyTrack Server Projects Fast datastore (C++)
- Implements multi-resolution data tiling on top of key/value store (default is filesystem)- Scales to 1TB per channel- Response time < 10 msec for tiles at any level of detail, even summary of entire 1TB- In process of deploying to alpha website to replace original MySQL-based datastore
BodyTrack Website (Ruby On Rails, MySQL)- Very active development; currently in transition to incorporate fast datastore- REST APIs for data upload and, query of device/channel data for account, and multi-res tile fetch
Explorable data viewer (Javascript/HTML5 Canvas/GWT)- Interactive exploration of very large datasets - Pulls in data on the fly as user zooms and explores- In process of specifying interface to Website and making available as separate project
