Smart Connected Sensors

Platform for full-body motion tracking

Smart Connected Sensors

Move. Prove. Improve.

Smart Connected Sensors enables full-body movement analysis to be carried out. By combining qualitative and quantitative movement feedback, the platform not only enables body analysis but also gives indications on physical performance and a way to improve it. Areas of application can include fitness and rehabilitation, but also gaming in combination with AR/VR applications. By improving movement results, a higher level of fun, health and experience can be achieved. The sensor platform provides qualitative feedback based on integrated AI features and comes with a pattern creation software tool that helps customers customize their system design. By using this tool, the customer retains control over their data, as there is no need for regular data exchange with Bosch Sensortec. To save customers precious time and effort, Bosch Sensortec provides business customers with the full package:

  • BHI380, a programmable IMU-based sensor system using AI functionality
  • A wearable reference design that can be straightforwardly attached to any part of the body without having to handle cable clutter, an external camera or dedicated bodysuits
  • Software features including gesture and activity recognition, body movement detection, relative body angle information, as well as a feedback coach

Use Cases

The key use cases will include rehabilitation, body movement tracking and joint analysis according to the motto “Move. Prove. Improve.”

Main Target Application

Thanks to the versatile modular system, the Smart Connected Sensors can be installed in many applications and use cases, such as wearables, hearables and AR/VR headsets.
