piezoelectric crystal
A piezoelectric crystal converts pressure into an electrical signal in a laboratory sensor.
Noun: A piezoelectric crystal is a specific type of crystal that exhibits the piezoelectric effect. This means it can generate an electric voltage when mechanical stress is applied to it, and conversely, it can change shape slightly when an electric voltage is applied to it. This property makes it useful for converting between mechanical energy and electrical energy.
This term is used in technical and scientific contexts, particularly in physics, engineering, and electronics, to describe the material component of various devices. - It functions as a countable noun (e.g., a piezoelectric crystal, several piezoelectric crystals). - It is often modified by the type of material (e.g., quartz piezoelectric crystal) or its application.
- As a subject:
- As an object:
- With a modifier:
- In Device Contexts: The term is central to describing the operational principle of specific components.
- The accuracy of the watch depends on the stability of its tiny piezoelectric crystal.
- In Research and Development: Used when discussing material properties or new applications.
- Their research focuses on growing more efficient piezoelectric crystals for energy harvesting.
- Piezoelectricity (n): The general phenomenon or property exhibited by piezoelectric crystals.
- Piezoelectric (adj): Describing the effect or a material having this property (e.g., , ). Note: This is the adjective form, not the noun phrase itself.
- Transducer (n): A broader category of devices that convert energy from one form to another; a piezoelectric crystal is often the active element within a transducer.
- Piezoelectric element: A very close synonym, though it can refer to a manufactured component that may contain the crystal.
- Piezoceramic (n): Specifically refers to a man-made polycrystalline piezoelectric material, often used in similar applications but with a different microstructure than a single crystal.
- Piezoelectric effect: The fundamental physical phenomenon.
- Direct piezoelectric effect: Generating electricity from mechanical stress.
- Inverse (or converse) piezoelectric effect: Generating mechanical movement from electricity.
- Crystal oscillator: A common electronic circuit that uses a piezoelectric crystal to create a precise frequency signal.
