Second generation complementary and alternative medicine physiologic data collection and monitoring research platform.

Progress on our second generation portable system specifically designed to collect 24 hour ambulatory physiologic data from human subjects is reported. The upgraded system has more sensor flexibility and better performance and is smaller, lighter, and simpler to use than our previous version. The new system continues to support a wide variety of sensors found useful for complementary and alternative medicine (CAM) research and has been designed using a modular approach for future expansion of capabilities. The system has improved data storage and supports popular physiologic data formats. Support for wireless control and real-time data monitoring has been added which demonstrates capabilities to be used for physiologic feedback control. The system was designed specifically to support the needs of investigators studying CAM mind-body interventions but could be used for a variety of research needs.
