Bosch’s BHI260AP self-learning AI smart sensor for fitness tracking

Athletes have started relying on fitness trackers to monitor their daily exercise and to improve their performance. After a series of developments in smart trackers for athletes, Bosch has now released its new self-learning AI smart sensor – BHI260AP specially designed for fitness tracking, navigation, machine learning analytics, and orientation estimation.

“The self-learning AI sensor will change how users interact with their fitness devices from a mere one-way approach to an interactive way of training”, says Dr. Stefan Finkbeiner, CEO at Bosch Sensortec. “This new sensor combines Bosch Sensortec’s long-term experience in smart motion sensors with its strong competence in innovative software development.”

The company uses the term “One piece of software – four features” indicating that it is a self-learning sensor that can be personalized and features auto-tracking with enhanced ability. Auto-track is the automatic tracking of fitness activities without user intervention. This comes with self-learning AI software that is provided with more than fifteen pre-learned fitness activities.

The AI sensor is based around Synopsys’s popular ultra-low-power DesignWare ARC EM4 processors with ARCv2 16/32-bit instruction set clocked up to 3.6 CoreMark/MHz. The EM4 processor supports the floating-point unit and comes along with the memory protection unit. BHI260AP has an integrated 16-bit 3-axis accelerometer and gyroscope sensors.

The manufacturer offers a wide range of software support for self-learning AI sensors. This means that the manufacturer of a wearable device can easily load the required software onto the sensor for those targeted applications or specific use cases including orientation tracking, position tracking (PDR), and swimming.

“Since the BHI260AP is a fully programmable sensor, manufacturers can build their own customized software to be embedded in the BHI260AP or upload customized solutions depending on the users’ context. To protect these customized solutions from unauthorized use, the smart programmable sensor offers a digital signature.”

To make development easier for AI-based wearable solutions, the manufacturer provides an application board along with a BHI260AP shuttle board that can be connected over Bluetooth Low Energy (BLE) to smartphones.

The BHI260AP self-learning AI sensor is available via Bosch Sensortec’s distributors along with the software packages that are available for download on the Bosch Sensortec website.
