Overview
IEC TS 61994-5:2023 is the IEC Technical Specification (Edition 2.0, 2023‑09) that provides a consolidated glossary of terms and definitions for piezoelectric sensors. It defines state-of-the-art vocabulary used in the manufacture and specification of piezoelectric elements, cells, modules and systems. This edition updates and expands the terminology by incorporating new terms from IEC 63041‑1:2021 and IEC 63041‑3:2020. As a glossary (no normative references), its primary purpose is to harmonize language across industry, R&D, testing and standards work.
Key topics
- Scope: Terms and definitions covering piezoelectric sensor elements, cells, modules and systems.
- Sensor types defined: e.g. delay line type sensor element (SAW transversal filter type), non-acoustic type, differential sensor, dual mode sensor, multi‑measurand sensor.
- Functional sensor element definitions: Specific piezoelectric sensor element categories such as acceleration, biochemical, chemical (gas), film‑thickness, force, humidity, and pressure sensor elements.
- Component and system definitions: Clear distinctions between piezoelectric sensor element, sensor cell (element + mechanical attachments), sensor module (element/cell + electronics), and sensor system (modules + devices/software).
- Terminology updates: Incorporation of recently established terms from IEC 63041 series to reflect modern sensor architectures and multifunction sensing approaches.
- Documentation guidance: Terms are aligned with IEC Electropedia and ISO/IEC directives to support consistent international use.
Applications and practical value
- Product design & manufacturing: Use standardized definitions to specify piezoelectric elements, interfaces and modules precisely during product development and supplier contracts.
- Specification & procurement: Avoid ambiguity in datasheets and procurement documents by referencing IEC TS 61994‑5 terms.
- Test laboratories & certification: Ensure consistent test descriptions and reporting for piezoelectric sensors.
- R&D and system integration: Facilitate communication across multidisciplinary teams (materials, electronics, firmware, analytics) when developing dual‑mode or multi‑measurand sensors.
- Industry examples: Film‑thickness control in vacuum deposition, inertial measurement systems, gas sensing, biochemical detection, and oil/gas exploration systems use the vocabulary defined in this TS.
