From 6–8 May 2025, the SENSOR+TEST trade fair presented the latest innovations in sensor, measurement and testing technologies. The event welcomed around 5000 visitors and 348 exhibitors from 24 nations, who showcased solutions to make industrial systems cleaner, smarter and more connected.
STMicroelectronics was there with edge-AI MEMS, ultra-low-power connectivity and sustainability demos. We also competed as a top-five finalist for the AMA Innovation Award with the IIS2DULPX accelerometer and exchanged ideas with customers facing design challenges.
Tools tracking with ISM330BX and LSM6DSV80X/320X
One of the demos featured the ISM330BX. When using power tools such as drills, it is very common for the drill to get stuck and rotate in an uncontrolled way in the user’s hands. This rotational movement can be detected with the ISM330BX industrial IMU in order to stop the motor, preventing wrist injuries.
We also displayed our latest high-g IMUs: the LSM6DSV80X and LSM6DSV320X can be used to measure impacts up to 80g and 320g in different industrial applications and to log estimated drop height. Both IMUs integrate a low-power 16 g channel for always-on wake-up, running at couple of microamps power level. The result is a compact, robust reference design that helps OEMs meet safety standards while keeping tools light, quiet and efficient.
Predictive maintenance with IIS2DULPX
Shortlisted for the AMA Innovation Award, the IIS2DULPX accelerometer was highlighted for its low-power Edge AI processing capabilities. In the demo, it monitored vibration levels on a fan, classifying them using Machine Learning Core (MLC).
This sensor detects changes in motor speed, reducing system-level power consumption. It’s designed for harsh industrial environments, operates up to 105 degrees Celsius and offers a 10-year longevity commitment, making it ideal for industrial IoT applications.
A helmet for bio-signal detection, powered by ST1VAFE3BX
Industrial safety often starts with the operator, which is why we fitted a construction helmet with our new ST1VAFE3BX biosensor. The device combines an accelerometer and vertical Analog Front End to synchronously capture motion and ECG through forehead-mounted dry electrodes (no chest straps required).
The demo detects eye blinks, head turns and heart-rate anomalies, flagging early signs of fatigue in real time on a connected dashboard. The integration of an accelerometer and vertical Analog Front End (vAFE) allows for synchronous signal capture, compensating for movement artifacts.
ST87M01: NB-IoT kit & DigiBee
Connectivity is key for sensor applications and the ST87M01 module enables real-time monitoring through the Narrow Band IoT network. A beehive demo, featuring an NB-IoT-enabled weight scale, showed how to monitor natural environments remotely.
A low-power weight sensor tracks the “honey” level, while an on-board PMIC, environmental sensors, and an STM32 handle energy harvesting and analytics. Users receive updates every minute via NB-IoT, which is ideal for remote forests, where pollinator health matters most.
“Hank”, the robotic hand
At our reception desk, visitors were greeted by “Hank”, a robotic hand which mirrored their hand movements.
The system is trained with AI algorithms and, by using the VD66GY global shutter image sensor and STM32N6 microcontroller, captures and processes hand movements, translating them into commands for the robotic hand. This demo highlighted the potential for robotics in enhancing human-machine interaction, offering a glimpse into the future of industrial automation.
