Sensor Fusion in the Spotlight

Sensor Fusion is both a hardware and software solution and begins with the combination of more than one sensor.  But there is much more to this solution than integrating sensors.  The objective is to combine the data collected by the sensors in order to extract and use the information.  This requires an algorithm which works with the operating system and makes data available to high level applications such as personal navigation, activity monitoring, context awareness and augmented reality.  This algorithm is often embedded in a microcontroller known as a sensor hub which connects to an applications processor.

On September 23, 2013 ST and Movea announced their agreement to integrate Movea’s SmartMotion technology into the STM32F401 microcontroller operating as a low-power sensor-hub controller.

ST is the leading supplier of MEMS sensors for the consumer and communications market, in particular smart phones.  The company also offers it line of ST32 ARM based MCUs as sensor hub controllers. 

Movea is a leading provider of Sensor Fusion algorithms offering data fusion and motion processing firmware, software, and IP for the consumer electronics industry.  The company offers a comprehensive set of SW, firmware and tools to enable an advanced-motion user experience. 

Movea’s firmware will be integrated into the STM32F401 sensor management platform.  The STM32F401 with SmartMotion technology and tools will be available in Q4 2013.

Why is this such a significant development? For a few years ST has been offering its iNEMO sensor fusion platform solution.  It appears that it will incorporate Movea’s technology and expertise, at least for this MCU.  But this could indicate further cooperation in the future.  This offers improved performance for ST’s solutions.  Movea is working with the leading MEMS supplier for its target markets.  This is a major design win for Movea.
