Piezoelectric fiber composite
A piezoelectric fiber composite is a flexible actuator or sensor made of piezoelectric ceramic fibers in a polymer matrix, best known through NASA's Macro-Fiber Composite of 1999.
Piezoelectric sensor
A piezoelectric sensor, also called a piezo sensor, is a transducer that converts mechanical quantities such as force, pressure, vibration, and strain into electrical signals using the piezoelectric effect.
Piezoelectric surgery
Piezoelectric surgery, also called piezosurgery or piezoelectric bone surgery, cuts bone with ultrasonic microvibrations that spare adjacent soft tissue such as nerves, vessels, and mucosa.
Piezoelectric transducer
A piezoelectric transducer is a device that converts electrical energy into mechanical vibration, or mechanical vibration into electrical signals, using piezoelectric materials such as quartz, PZT ceramics, or polymers.
Piezoelectricity
Piezoelectricity, also called the piezoelectric effect, is the ability of certain crystals to generate electric charge when mechanically stressed, first demonstrated by the Curie brothers in 1880.
Piezometer
A piezometer is an instrument or well that measures groundwater pressure at a specific point in the subsurface, commonly used to monitor seepage in dams.
PiezoMotor
A piezoelectric motor converts the deformation of a piezoceramic element into rotary or linear motion, achieving sub-nanometer precision and 30 to 100 times the force density of small electromagnetic motors.
Piezophilic archaea of the deep sea
Piezophilic archaea are archaeal microorganisms that grow more rapidly under high hydrostatic pressure than at atmospheric pressure, known mostly from deep-sea hydrothermal vents, where they are also thermophiles.
Piezoresistive sensor
A piezoresistive sensor measures pressure, force, strain, or acceleration by converting mechanical stress into a resistance change. Widely used in MEMS, its standard form uses four silicon piezoresistors in a Wheatstone bridge.
Piezoresistive tactile sensor
A piezoresistive tactile sensor is a touch sensor that measures pressure or strain through a change in electrical resistance, detecting both the intensity and location of a contact force.
Piezoresponse force microscopy
Piezoresponse force microscopy (PFM) is a scanning probe technique using a biased AFM tip to map piezoelectric and ferroelectric domains, detecting sub-picometer deformations with nanometer resolution.
Piezosurgery
Piezosurgery, or piezoelectric bone surgery, is a technique that cuts bone with modulated ultrasonic microvibrations, sparing adjacent nerves, blood vessels, and soft tissue; it is used in sinus lift, ridge expansion, and implant site preparation.
Piff the Magic Dragon
Piff the Magic Dragon (John van der Put) is an English comedy magician in a dragon costume, AGT Season 10 finalist (2015), headlining the Flamingo Las Vegas since 2015 with chihuahua sidekick Mr Piffles.
Piflufolastat
Piflufolastat (18F-DCFPyL; Pylarify in the US, Pylclari in the EU) is a fluorine-18-labeled PSMA-targeted PET radiotracer for staging and detecting recurrent prostate cancer, FDA approved May 2021.
Pifoxime
Pifoxime (pifoxima, CAS 31224-92-7) is a piperidine oxime NSAID and peripheral analgesic once sold in France as Flamanil and withdrawn after three months for toxicity; usual dose 600 mg/day oral.
PIFSS-Wafra
PIFSS-Wafra is the investment complex through which Kuwait's Public Institution for Social Security invests in alternatives via wholly owned Wafra vehicles in New York and Kuwait.
Pig
Pig (Sus domesticus, Sus scrofa domesticus): domesticated omnivore from the Eurasian wild boar, independently domesticated in Mesopotamia and China, raised worldwide for pork in systems from scavenging backyard herds to intensive confinement units.
Pig (2021 film)
Pig (2021) is Michael Sarnoski's debut drama starring Nicolas Cage as Rob, an Oregon truffle hunter searching Portland for his kidnapped foraging pig; acclaimed (96% RT, Metascore 82), grossed $3.1M, distributed by Neon.
Pig (猪) (zodiac)
The Pig (猪), also called the Year of the Pig or Year of the Boar, is the twelfth and final animal of the Chinese zodiac, paired with the Earthly Branch Hai.
Pig Beach
Pig Beach is Big Major Cay, an uninhabited cay in the Exuma Cays, Bahamas, home to about 20 feral swimming pigs descended from livestock relocated from Staniel Cay in the early 1990s, reachable only by boat.
Pig butchering scam
Pig butchering scam (sha zhu pan, 杀猪盘), also called cryptocurrency investment fraud or romance baiting: a confidence scam using fake crypto platforms, run from Southeast Asian scam centers with trafficked labor, causing billions in losses.
Pig farming
Pig farming (swine production), raising domestic pigs for pork, spans backyard smallholdings to intensive indoor systems. Key facts: domesticated ~10,500 years ago, litters of 14+ piglets, feed is 60–80% of cost, African swine fever is the main disease threat.
Pig intelligence
Pig intelligence refers to the cognitive abilities of the domestic pig, measured in behavioral tests: pigs learn and remember tasks, show social cognition, and smell possibly better than dogs.
Pig iron
Pig iron, or crude iron, is the high-carbon iron smelted from ore in a blast furnace, too brittle to work directly and mostly refined into steel.
Pig Latin
Pig Latin is an English language game that moves each word's initial consonant cluster to the end and adds "ay" (vowel words take "way"); first recorded 1840–45, with slang words ixnay and amscray.
Pig War (1859)
The Pig War (1859) was a U.S.-British standoff over San Juan Island after settler Lyman Cutlar shot a Hudson's Bay Company pig; resolved by 1872 arbitration under Kaiser Wilhelm I in favor of the United States.
Pig-Pen
Pig-Pen (also Pigpen) is the perpetually dirty Peanuts boy created by Charles M. Schulz, first appearing July 13, 1954, enveloped in a permanent dust cloud, appearing in about 100 of 17,897 strips, last seen in 1999.
Piga khanda
Piga khanda, standardly Pūga Khaṇḍa (पूग खण्ड), also called Supari Paka, is a granular Ayurvedic confection based on purified areca nut, sugar, ghee, milk, amalaki, and shatavari; dosed 5–15 g and indicated for amlapitta, vomiting, vertigo, heart disease, and syncope.
PIGA, GPI anchor biosynthesis
PIGA (PIG-A, Xp22.2) is the human X-linked gene encoding the catalytic subunit of GPI-GlcNAc transferase, the first step of GPI anchor biosynthesis; somatic mutations cause PNH, germline variants cause MCAHS2.
