Electronic Gaming Monthly
Electronic Gaming Monthly (EGM) is an American monthly console video game magazine founded by Steve Harris, published in print from 1989 to 2009 and online since 2010.
Electronic harassment
Electronic harassment is the unverified belief of being remotely attacked or controlled via directed energy weapons or voice-to-skull technology, held by self-identified targeted individuals within the gangstalking belief system, generally assessed clinically as persecutory delusion.
Electronic health record
Electronic health record (EHR), also called electronic medical record: a digital collection of a patient's medical information. Developed from 1960s systems like COSTAR and VistA; key issues are interoperability standards (HL7, FHIR) and clinician documentation burden.
Electronic health record review
Electronic health record review is a data collection method in epidemiology and clinical research that extracts patient information from EHRs to study exposures, outcomes, and care patterns.
Electronic interlocking
An electronic interlocking, known in Germany as the Elektronisches Stellwerk (ESTW), is a computerised signaling system that sets switches and signals so train movements are only authorized when safety conditions are met.
Electronic journal
An electronic journal, or e-journal, is a periodical published in digital form, most commonly the online version of a scholarly print journal, commercially widespread since the mid-1990s.
Electronic Journal of Combinatorics
The Electronic Journal of Combinatorics (E-JC) is a peer-reviewed open-access online journal for discrete mathematics, founded in 1994 by Herbert Wilf and Neil Calkin as one of the first journals delivered over the World Wide Web.
Electronic keyboard
Electronic keyboard: a keyboard instrument producing sound electronically; covers portable and arranger keyboards, distinct from digital pianos, synthesizers, and MIDI controllers. Born early 1980s (Yamaha PortaSound 1980, DX7 1983), MIDI standard, widely used in music education.
Electronic lab notebook
An electronic lab notebook (ELN) is a computer system used to create, store, retrieve, and share electronic research records in place of a paper lab notebook.
Electronic logging device
An electronic logging device (ELD) synchronizes with a commercial vehicle's engine to automatically record driving time and hours of service, replacing paper logs for most US interstate drivers since 2017.
Electronic media
Electronic media are communication media that encode, store, or transmit messages using electronic technology, as opposed to print, covering broadcasting, recorded audio and video, telephony, and internet-based services.
Electronic music
Electronic music (电子音乐): music generated or processed with electronic instruments and technology such as synthesizers, drum machines, and computers; a medium rather than a genre, tracing from the Telharmonium and theremin to tape studios, MIDI, dance subgenres, and a $15.1 billion 2025 industry.
Electronic music festivals in the Americas
Electronic music festivals in the Americas are large multi-day EDM events, anchored by EDC Las Vegas and Ultra Miami, with Creamfields Buenos Aires and Tomorrowland Brasil leading South America.
Electronic musical instrument
An electronic musical instrument produces or shapes sound using electric or electronic circuitry, ranging from electromechanical instruments like the Hammond organ to fully electronic ones like the theremin and synthesizer.
Electronic navigational chart
An electronic navigational chart (ENC) is a standardized vector chart database issued by a government-authorized hydrographic office for use with ECDIS, conforming to International Hydrographic Organization standards.
Electronic nematicity
Electronic nematicity is a phase of matter in which electrons in a crystal spontaneously break its rotational symmetry, a concept central to iron-based and copper oxide superconductors.
Electronic nematicity in iron-based superconductors
Electronic nematicity in iron-based superconductors is the spontaneous breaking of the crystal's rotational symmetry by electronic order; in FeSe it occurs near 90 K without magnetism.
Electronic Nose
An electronic nose (e-nose) is an instrument that mimics biological olfaction, using an array of broadly tuned gas sensors and pattern-recognition algorithms to identify complex odors, first built in 1982.
Electronic oscillator
An electronic oscillator is a circuit that generates a repeating signal, using an amplifier with frequency-selective feedback; common designs include Hartley, Colpitts, Pierce, Wien bridge, ring, and LC oscillators.
Electronic paper
Electronic paper, also known as e-paper, is a reflective display technology that mimics ink on paper, best known through Amazon Kindles and electronic shelf labels.
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.
