BlueSense2 - Wearable/IoT sensing platform and inertial measurement unit

BlueSense2

Purpose

BlueSense2 is a wearable/IoT platform designed to be functional out-of-the-box yet extensible. It's primary purpose is to be an inertial measurement unit for wearable applications. Yet it is extensible for IoT applications with a number of features making it appealing for this purpose

BlueSense2 as a wearable platform is a tiny device which can be used to capture body movement with a 9DoF motion sensor. The data can either be logged on an SDCard or streamed over bluetooth. This forms the core of a fitness tracker. Its extension ports allow to plug-in additional sensor modalities for research purposes (e.g. electric potential sensors). A display is being developed converting it into a smartwatch.

As an IoT device it's main appeal is a true hardware off which allows to put the device entirely to sleep (everything is powered down, including voltage regulators), yet wake up at programmed intervals thanks to a real-time clock wakeup. This allows to achieve very long battery life, as the device can wake up at desired times (once an hour, once a day, ...) to acquire and send sensor data. The extension ports allow to plug in custom sensor modalities which make this device highly versatile.
