Osmium MIMU22BL

A Precision Wearable Motion Sensor Platform (IMU)

An IMU-array based Precision Wearable Motion Sensor Platform (IMU) - The Osmium MIMU22BL - is a miniaturized motion sensing multi-IMU (MIMU) platform, configured as shoe-based Pedestrian Dead Reckoning (PDR) sensor for real-time indoor localization in GPS denied environment. It is a smart IoT sensor node, capable of providing simplified yet information rich data, thereby relieving application platform and developers from the compute intensive development and tasks. This greatly simplifies data interface and makes integration of this device with rest of the localization system, effortless. Thus resultig in improved tracking accuracy, relaxes constraints on the integration platform and significantly reduces time-to-market.

Presence of on-board floating point processing capability, along with four IMUs array, makes sensor fusion and motion processing possible within the module itself, which in turn results in very accurate motion sensing. Being one of the thinnest IMU in the market, it is suitable for applications with space constraints, e.g. wearable motion sensing. It finds applications in indoor real-time location systems (RTLS) for industrial workers and first responders. It also has applications in robotics, urban geo-survey, AR, gaming, gait biomechanics, wearable IoT etc.
