Sensors have the potential to fundamentally change our daily lives: from fitness tracking to air quality measurement, they make modern devices smarter and more user-friendly. To achieve this, Bosch Sensortec combines its MEMS technology with embedded microcontrollers, software and artificial intelligence directly in the sensor. This combination is designed to enable innovative applications and enhance the systems as a whole. “Our innovative sensor solutions are driving progress in areas such as health, smart homes and smart cities,” explains Stefan Finkbeiner, CEO of Bosch Sensortec, and emphasizes: “AI and intelligent software are the key technologies that make these developments possible.”

Vision 2030: Over 10 billion intelligent sensors

According to market research firm Yole, Bosch has held the top position in the MEMS market for four consecutive years. In 2024, the milestone of one billion shipped MEMS sensors with integrated software and microcontrollers was exceeded. From 2027, 90 percent of products will include these integrated functions. By 2030, Bosch aims to increase this figure to 10 billion – with increasingly intelligent and connected sensor solutions. Thanks to edge AI, data processing takes place directly in the sensor – without a constant cloud connection. According to Bosch, this ensures higher data security, reduced latency and significantly lower energy consumption. Users benefit from precise real-time feedback.

Always ready to use thanks to always-on technology

Always-on technology extends battery life and enables intuitive use: voice assistants, fall detection in smartwatches, and automatic adjustment of smartphone modes are just a few examples. MEMS sensors with integrated software ensure that devices are always ready – without activating the main processor. Advanced software solutions optimize not only the sensor, but the entire system. They create new application possibilities and form the basis for AI directly in the sensor.

Smart Connected Sensors (SCS): Your personal AI coach

Imagine having unlimited access to a professional fitness trainer who is always there to give you feedback. This could be the future of fitness training. The Smart Connected Sensors platform from Bosch Sensortec is set to make it possible. The SCS platform provides qualitative feedback to users on how they are performing the movements, as well as measuring movements and repetitions. It has been specifically designed for full-body motion tracking and offers a fully integrated hardware and software solution (based on the BHI380, a programmable IMU-based sensor system with AI) that drastically reduces development costs and time to market.

Revolution in voice control

Wireless headsets have transformed the way people listen to music, podcasts and audiobooks. They allow free, unimpeded movement and offer new possibilities through sensor-based functions such as activity recognition and indoor navigation. However, the switch to voice control can cause problems if the system is unintentionally triggered because it responds to ambient noise. To solve this problem, Bosch Sensortec developed a software-based innovation: a novel acceleration sensor, the BMA550, detects sounds through bone vibrations. Intelligent algorithms ensure that voice control is only activated when the headset wearer is actually speaking.

Clean air: precise measurement of particulate matter

Poor indoor air quality is a problem: the PM2.5 particulate matter generated by household cooking can reach levels 100 times higher than permissible limits. Localized, meaningful data from the Bosch particulate matter sensor for PM2.5 and PM1 make it possible to respond to poor air quality in a targeted manner. A software update, available soon, extends the measurement capabilities to PM10. 99 percent of the world's population breathes air that exceeds WHO air quality limits. Bosch's BMV080 sensor uses software and intelligent algorithms to measure particulate matter in a tiny, fanless design – 450 times smaller than comparable devices.

Open platforms for co-developments

For all these possibilities, Bosch offers open platforms to support customers in developing specific algorithms. These models can then be executed on a smart motion sensor like the BHI360. For example, Bosch Sensortec and Doublepoint have jointly developed a powerful micro-gesture control solution for smartwatches that utilizes the BHI360. This enables always-on, reliable control, for example, allowing users to adjust light brightness with an intuitive pinch gesture. “This partnership underscores our commitment to providing manufacturers with rapid access to advanced IoT and wearable technologies,” said Lucas Ginzinger, vice president of Marketing and Business Strategy at Bosch Sensortec. Doublepoint's advanced algorithms are seamlessly integrated into Bosch's compact, low-power IMUs via a new software tool. Compared to camera-based solutions, this IMU-based approach enables unobstructed gesture recognition and offers greater reliability and efficiency.
