Recent advances in wearable sensors have surged in novel fitness and preventive health care systems that measure step counts, activity levels, and performed exercises with inertial sensors, enabling users to monitor condition and day-to-day lifestyle. This paper presents a middleware designed for a Smartphone unit to support health monitoring applications. Its event-driven architecture enables modular system design and seamless switching between sets of embedded sensors. The strengths of the middleware are highlighted in a deployed feasibility study where daily and gym activities are recognized through an interchangeable set of wireless sensors.
