PIEZO1
Piezo1 is a mechanosensitive ion channel protein that in humans is encoded by the gene ''PIEZO1''. Piezo1 and its close homolog PIEZO2, Piezo2 were cloned in 2010, using an siRNA-based screen for mechanosensitive ion channels. Structure and function PIEZO1 (this gene) and PIEZO2 share 47% identity with each other and they have no similarity to any other protein and contain no known protein domains. They are predicted to have 24-36 transmembrane domains, depending on the prediction algorithm used. In the original publication the authors were careful not to call the piezo proteins ion channels, but a more recent study by the same lab convincingly demonstrated that indeed piezo1 is the pore-forming subunit of a mechanosensitive channel. This new "PIEZO" family is catalogued as and TCDB . PIEZO1 homologues are found in ''C. elegans'' and ''Drosophila'', which, like other invertebrates, have a single piezo protein. It is known () that Piezo1 channel is a three-bladed propeller-lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pickup (music Technology)
A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly. Most electric guitars and electric basses use magnetic pickups. Acoustic guitars, upright basses and fiddles often use a piezoelectric pickup. Magnetic pickups A typical magnetic pickup is a transducer (specifically a variable reluctance sensor) that consists of one or more permanent magnets (usually alnico or ferrite) wrapped with a coil of several thousand turns of fine enameled copper wire. The magnet creates a magnetic field which is focused by the pickup's pole piece or pieces. The permanent magnet in the pickup magnetizes the guitar string above it. This causes the string to generate a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piezoelectric Sensor
A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix ''piezo-'' is Greek for 'press' or 'squeeze'. Applications Piezoelectric sensors are versatile tools for the measurement of various processes. They are used for quality assurance, process control, and for research and development in many industries. Pierre Curie discovered the piezoelectric effect in 1880, but only in the 1950s did manufacturers begin to use the piezoelectric effect in industrial sensing applications. Since then, this measuring principle has been increasingly used, and has become a mature technology with excellent inherent reliability. They have been successfully used in various applications, such as in medical, aerospace, nuclear instrumentation, and as a tilt sensor in consumer electronics or a pressure sensor in the touch pads of mobile phones. In the automoti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piezoelectric Speaker
A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and this motion is typically converted into audible sound using diaphragms and resonators. The prefix ''piezo-'' is Greek for 'press' or 'squeeze'. Compared to other speaker designs piezoelectric speakers are relatively easy to drive; for example they can be connected directly to TTL outputs, although more complex drivers can give greater sound intensity. Typically they operate well in the range of 1-5 kHz and up to 100 kHz in ultrasound applications. Usage Piezoelectric speakers are frequently used to generate sound in digital quartz watches and other electronic devices, and are sometimes used as tweeters in less-expensive speak ...

Piezoelectricity
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word ''piezoelectricity'' means electricity resulting from pressure and latent heat. It is derived from the Greek word ; ''piezein'', which means to squeeze or press, and ''ēlektron'', which means amber, an ancient source of electric charge. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electrical field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piezometer
A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure (more precisely, the piezometric head) of groundwater at a specific point. A piezometer is designed to measure static pressures, and thus differs from a pitot tube by not being pointed into the fluid flow. Observation wells give some information on the water level in a formation, but must be read manually. Electrical pressure transducers of several types can be read automatically, making data acquisition more convenient. Groundwater measurement The first piezometers in geotechnical engineering were open wells or standpipes (sometimes called Casagrande piezometers) installed into an aquifer. A Casagrande piezometer will typically have a solid casing down to the depth of interest, and a slotted or screened casing within the zone where water pressure is being measured. The casing is seal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piezoresistive Effect
The piezoresistive effect is a change in the electrical resistivity of a semiconductor or metal when mechanical strain is applied. In contrast to the piezoelectric effect, the piezoresistive effect causes a change only in electrical resistance, not in electric potential. History The change of electrical resistance in metal devices due to an applied mechanical load was first discovered in 1856 by Lord Kelvin. With single crystal silicon becoming the material of choice for the design of analog and digital circuits, the large piezoresistive effect in silicon and germanium was first discovered in 1954 (Smith 1954). Mechanism In conducting and semi-conducting materials, changes in inter-atomic spacing resulting from strain affect the bandgaps, making it easier (or harder depending on the material and strain) for electrons to be raised into the conduction band. This results in a change in resistivity of the material. Within a certain range of strain this relationship is linear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinereous Finch
The cinereous finch (''Piezorina cinerea'') is a species of South American bird in the tanager family Thraupidae. It is the only member of the genus ''Piezorina''. It is found in arid coastal regions of northern Peru, with a single record, presumably a straying bird, from immediately adjacent Ecuador. Taxonomy The cinereous finch was formally described in 1843 by the French ornithologist Frédéric de Lafresnaye under the binomial name ''Guiraca cinerea''. In the same publication he proposed a new genus ''Piezorina'' with the cinereous finch as the type species. Lafresnaye believed that his specimen had come from the Galápagos Islands, but it does not occur there and in 1930 the American ornithologist Outram Bangs amended the type location to northwest Peru. The genus name combines the Ancient Greek ''piezō'' meaning "to crush" with ''rhinos'' meaning "nose". The specific epithet ''cinerea'' is Latin and means "ash-grey" or "ash-coloured". The species is monotypic: no subspecie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piezo Ignition
Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to mechanical deformation. It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas. No external electric connection is required, though wires are sometimes used to place the sparking location away from the crystal itself. Piezo ignition systems can be operated by either a lever, push-button or built into the control knob. An electric spark An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures. ...
