Electronic parking brake
An electronic parking brake (EPB) is a parking brake controlled electrically, typically by a switch, replacing the hand lever on most new cars since the 2010s.
Electronic pest control
Electronic pest control: ultrasonic and electromagnetic devices claiming to repel rodents and insects. Regulated as EPA devices without efficacy review; FTC enforcement since 1985; controlled studies show habituation within 3-7 days and marginal effects.
Electronic prescribing
Electronic prescribing (e-prescribing) is the electronic transmission of a structured medication order from prescriber to pharmacy, replacing paper prescriptions; in the US it became the dominant channel by 2013.
Electronic program guide
An electronic program guide, also called an electronic service guide, is an on-screen menu listing television channels' current and upcoming programs with titles, start times, and durations.
Electronic properties of condensed matter
The electronic properties of condensed matter determine whether solids conduct as metals, semiconductors, or insulators, with band gaps and electron interactions explaining behavior from silicon to superconductors.
Electronic publishing
Electronic publishing (e-publishing, digital publishing) is publishing based on machine-readable rather than printed editions. It began with Project Gutenberg's first ebook in 1971, now spans EPUB, PDF, and HTML formats, and has transformed scholarly journals, where open access holds about 20% of the market.
Electronic Road Pricing
Electronic Road Pricing is Singapore's electronic congestion-charging system, introduced in 1998 to replace the Area Licensing Scheme, which deducts fees automatically as vehicles pass roadside gantries during operating hours.
Electronic rock
Electronic rock (electro rock) is a music genre fusing rock and electronic music via guitars, synthesizers, and drum machines. Originating in the late 1960s after the Moog synthesizer's release, it spans industrial rock, synth-rock, indietronica, and dance-punk.
Electronic signature
An electronic signature, or e-signature, is data or an electronic sound, symbol, or process adopted with intent to sign a record, and it carries legal effect.
Electronic skin
Electronic skin, also known as e-skin or artificial skin, is a thin, flexible sensor system that mimics human skin sensing, with uses in health monitoring, robotics, and prosthetics.
Electronic speckle pattern interferometry
Electronic speckle pattern interferometry (ESPI), also called TV holography, is a non-contact optical metrology technique that measures surface displacement and deformation from laser speckle, developed from 1971 onward.
Electronic speed control
An electronic speed control (ESC) is a circuit that regulates the speed of an electric motor, most commonly in radio-controlled aircraft, cars, boats, and drones.
Electronic stability control
Electronic stability control (ESC), also called the Electronic Stability Program, is a vehicle safety system that brakes individual wheels to stop skids. It debuted in the 1995 Mercedes-Benz S 600.
Electronic symbol
An electronic symbol, also called a circuit or schematic symbol, is a standardized pictogram representing components such as resistors, batteries, and transistors in circuit diagrams, defined by the international IEC 60617 standard.
Electronic System for Travel Authorization
The Electronic System for Travel Authorization, or ESTA, is an automated U.S. system that screens Visa Waiver Program travelers before they board a carrier to the United States.
Electronic tagging
Electronic tagging (electronic monitoring, EM): ankle-worn devices used by courts, prisons, and parole authorities to enforce curfews, exclusion zones, and alcohol bans. First criminal justice order 1983; about 500,000 people monitored in 2022; cheaper than prison, costlier than probation.
Electronic throttle control
Electronic throttle control, also called throttle-by-wire, is an automotive technology in which an engine control unit positions the throttle with an electric motor instead of a cable.
Electronic ticket
An electronic ticket, or e-ticket, is an airline ticket stored in the airline's database rather than printed on paper, with only an itinerary receipt as evidence.
Electronic toll collection
Electronic toll collection (ETC) is a system that charges road tolls automatically, identifying vehicles electronically so drivers need not stop and pay cash at toll booths.
Electronic transition moment
The electronic transition moment is the matrix element of the electric dipole moment operator between two electronic states, determining whether a transition is allowed and how intense its absorption or emission line is.
Electronic trigger
An electronic trigger is a firearm firing control in which an electrical signal, rather than a mechanical linkage, releases or initiates the shot, first widespread in Olympic free pistols.
Electronic voice phenomenon
Electronic voice phenomenon (EVP), basis of instrumental transcommunication (ITC): voices on recordings interpreted as messages from the dead; begun by Jürgenson in 1959, popularized by Raudive's 1971 Breakthrough; explained as auditory pareidolia.
Electronic voting
Electronic voting (e-voting) covers poll-site voting machines and remote internet voting. Brazil and India use machines nationwide, Estonia alone offers internet voting to all citizens since 2005, and the US 2018 National Academies report recommends paper ballots.
Electronic voting in India
Electronic voting in India uses standalone, non-networked EVMs (control and balloting units) with VVPAT paper trails, first used in Kerala in 1982, VVPAT added in 2013 after Subramanian Swamy v. ECI, now M3 models made by BEL and ECIL.
Electronic waste
Electronic waste, or e-waste, is discarded electrical or electronic equipment and one of the world's fastest growing waste streams, reaching 62 billion kg in 2022.
Electronic–vibrational resonance in photosynthetic energy transfer
Electronic–vibrational resonance (vibronic resonance) in photosynthetic energy transfer is the near matching of an exciton energy gap to a pigment vibration, producing mixed electronic–vibrational quantum states.
Electronica
Electronica is a catch-all term for electronic music built on synthesizers, samplers, and drum machines, spanning club dance styles and headphone listening. Coined around the 1993 New Electronica compilations, broadened by the US industry, later partly replaced by EDM.
Electronically activated recorder
The electronically activated recorder (EAR) is a psychology research method developed by Matthias Mehl and James Pennebaker in which participants wear a recorder that periodically samples ambient sound.
Electronics
Electronics is the branch of physics and engineering that controls electron flow through components like vacuum tubes, transistors, and integrated circuits to amplify, switch, and process signals.
Electronics City
Electronics City is an industrial and information technology township on the Bengaluru–Hosur highway in Bengaluru, India, established in 1978 by KEONICS, with Infosys, Wipro, and more than 350 establishments.
