What is an IEEE Sensor? What are the Standards for IEEE Sensors in 2025?

IEEE sensors refer to devices that comply with IEEE standards and can convert non-electrical quantities into electrical signals for measurement and processing. The 2025 standards include: IEEE 3184.1-2025 Roadside Sensor Joint Calibration Framework Standard, IEEE 1451.0-2024 Smart Sensor Interface Standard, etc.

IEEE Sensor Technology Foundation and Definition

As the world’s largest professional technical organization, IEEE (Institute of Electrical and Electronics Engineers) covers the entire chain from basic theory to application practice. Sensors are defined in IEEE standards as “devices that can convert physical, chemical or biomass into measurable signals”, and their core functions include information perception, signal conversion and data transmission. According to the IEEE 1451 series of standards, smart sensors must have features such as self-description, self-identification, and self-diagnosis, and achieve plug-and-play functions through standardized interfaces.

IEEE SENSORS 2025

Technical essence:
The sensor interacts with the object being measured through sensitive elements, converting non-electrical quantities (such as temperature, pressure, light intensity) into electrical signals or other forms of signals. For example, PVDF-based piezoelectric sensors use the piezoelectric effect of polyvinylidene fluoride to convert mechanical stress into charge output. Its three-dimensional trapezoidal structure increases the output voltage by 1.23 times that of traditional planar sensors (IEEE MEMS2025 data).
