STの加速度センサは、スマートフォンや情報端末など、低消費電力と小型化が要求される様々な携帯型機器に適しています。STがリリースした次世代の加速度センサは大幅に小型化され、わずか2mm x 2mm x 1mmサイズ、14ピンおよび12ピンのパッケージで提供されます。






ST’s IIS2ICLX inclinometer wins the CES 2021 Honoree Innovation Award in the Smart Cities category

The high-accuracy IIS2ICLX two-axis digital accelerometer is ideal for structural health monitoring and inclination measurements, combining high stability and repeatability, low noise, and ultra-low-power with support for Artificial Intelligence at the edge. It is included in ST’s 10-year longevity program.

The IIS2ICLX features:

  • 2-axis digital plug-and-play inclinometer
  • the highest performance in terms of resolution, accuracy, stability, and power consumption
  • Ultra-low noise (15 µg/√Hz)
  • A programmable Machine Learning core to integrate AI algorithms and reduce power consumption at system level
    • The unparalleled set of features, such as the Machine Learning Core (MLC), programmable Finite State Machines (FSM), FIFO, sensor hub capabilities, and event decoding and interrupts, provide fundamental support for low power intelligent sensor nodes to reduce data transfer rates and volumes to the cloud.

      Thanks to its decision-tree algorithms, the IIS2ICLX significantly increases the autonomy of battery-operated applications by allowing nodes to remain in very low power standby until the sensor autonomously detects and classifies movement, vibration or variation in inclination.

New IIS3DWB sensing solution for wide scale adoption of vibration monitoring in Industry 4.0 applications

Optimized for high performance industrial vibration sensing, the 3-axis IIS3DWB MEMS accelerometer with an ultra-wide bandwidth and low-noise is a power-efficient and affordable digital sensing solution included in ST’s 10-year longevity program.

The IIS3DWB sensor is a key enabler of industrial vibration monitoring:

  • it offers a 3-axis digital plug-and-play solution for a seamless and cost-effective adoption
  • its wide and flat frequency response up to 6kHz and low noise ensure high-quality vibration data is collected
  • the sensor low-power and extended temperature range up to +105°C is ideal for long-lasting, self-powered wireless sensor nodes and allows them to be retrofitted into existing systems

The STWIN SensorTile development kit (STEVAL-STWINKT1B) takes the prototyping of vibration monitoring solutions to the next level. It integrates the IIS3DWB sensor with numerous additional sensors and an ultra-low-power STM32L4+ MCU, and offers wired and wireless connectivity. Software libraries for vibration processing are also available, including a high-speed data logger for data scientists to develop algorithms.
