piezoelectric axis
With respect to a crystal, one of the paths or axes that will exhibit a piezoelectric charge when subject to tension or compression.
piezoelectric crystal
A crystal consisting of a substance that has the ability to become electrically polarized and has strong piezoelectric properties. It is cut so as to emphasize the coupling to some distinct...
piezoelectric transducers and ceramic materials
Piezoelectric transducers are devices that utilize the piezoelectric effect to convert electrical energy into mechanical vibrations or vice versa. The piezoelectric effect is a property exhibited by...
piezoelectric
Piezoelectricity is a property exhibited by certain materials in which they generate an electric charge in response to mechanical stress or deformation, and conversely, undergo mechanical deformation...
accelerometer
An accelerometer is a sensor or transducer that measures the rate of change of velocity of an object, or in simpler terms, it measures acceleration. Accelerometers are widely used in various...
barium titanate
A crystalline material used in piezoelectric devices.
bimorph
A type of piezoelectric translator that uses two thin strips of piezoelectric material, one expanding while the other contracts, to produce movement.
bulk acoustic wave
A sound wave that travels through a piezoelectric material.
crystal filter
A bandpass filter with piezoelectric crystal components for the passage or impedance of electrical signals of various frequencies.
crystal oscillator
An oscillator that uses a piezoelectric crystal to control its frequency.
DPT
digital piezoelectric translator
ferroelectric materials
Ferroelectric materials are a type of dielectric materials that exhibit spontaneous electric polarization, meaning they possess a permanent electric dipole moment even in the absence of an external...
functional material
Functional materials refer to materials that possess specific properties or functionalities that make them suitable for particular applications or purposes. These materials are designed and...
inverse piezoelectric effect
The resulting contraction or expansion of a piezoelectric crystal along an electric axis when the crystal is under the influence of an electric field in the same direction.
lead zirconate titanate
A ferroelectric polycrystalline ceramic material used in optical memories for computers and as a piezoelectric transducer.
linear positioning stage
A linear positioning stage, also known as a linear stage or translation stage, is a precision mechanical device used to accurately move and position objects along a linear axis. These stages are...
lithium niobate
A crystalline ferroelectric material used primarily as a substrate and an active medium for thin-film optical modulators and switches. It possesses very high electro-optic and piezoelectric...
micro-robotics
Micro-robotics refers to the field of robotics that involves the design, development, and application of miniature robotic systems, often at the microscale. These robots, commonly referred to as...
motion controller
In optics, a motion controller refers to a device or system that precisely controls the movement of optical components, such as mirrors, lenses, stages, or other elements within an optical setup. The...
nanopositioning
Nanopositioning refers to the precise and controlled movement or manipulation of objects or components at the nanometer scale. This technology enables the positioning of objects with extremely high...
optical fiber optic switches
Optical fiber optic switches are devices used in optical fiber communication systems to selectively route optical signals from one input fiber to one or more output fibers. They play a crucial role...
phase shifting
A technique used to generate a phase shift between reference and sample light beams. The phase shift can be performed through the use of a mirror that is moved along the optic axis by a piezoelectric...
piezo worm
A piezoelectric translator that moves up and down a spindle like a caterpillar. It clamps itself at one end, expands, clamps the other end, releases the first end, and then contracts and begins the...
piezoelectric motion systems
Piezoelectric motion systems are mechanical systems that utilize piezoelectric materials to generate controlled motion or displacement. Piezoelectric materials exhibit the piezoelectric effect, which...
piezoresistance
Piezoresistance is a phenomenon in materials science and physics where the electrical resistance of a material changes in response to applied mechanical stress or strain. This change in resistance...
poling
The process of aligning the crystallites in a piezoelectric material by placing a large DC field across the element at an elevated temperature. The alignment of crystallites results in an increased...
PZT
piezoelectric transducer
scanning tunneling microscope
A high-resolution imaging instrument that can detect and measure the positions of individual atoms on the surface of a material. A very fine conductive probe is placed at a distance of 10 to 20...

piezo worm
A piezoelectric translator that moves up and down a spindle like a caterpillar. It clamps itself at one end, expands, clamps the other end, releases the first end, and then contracts and begins the...
tellurium
The material favored for study of interaction of high-acoustic intensities with free carriers. Tellurium is the semiconductor with the largest piezoelectric constants. Tellurium oxide is the material...
three-axis stage
A three-axis stage, also known as a three-axis positioning stage, is a precision mechanical device designed to control the position of an object in three perpendicular directions: typically X, Y, and...
transducer
A transducer is a device or component that converts one form of energy into another. It is commonly used in various fields, including electronics, acoustics, and instrumentation, to facilitate the...
ultrasonic camera
A device that uses a piezoelectric crystal to convert ultrasonic sound waves, transmitted through a subject, into a voltage that modulates the electron beam of a cathode-ray tube.
unimorph
A piezoelectric transducer made of a thin strip of piezoelectric material bonded to a strip of metal.
