Electronic Telepathy, or ''e-telepathy'', is a sub-trope of {{Telepathy}}. In most cases, characters using telepathic powers will do so by using some kind of supernatural force or a highly evolved biological mechanism that comes thanks to being a SufficientlyAdvancedAlien. However, in some cases, a character will have no natural or supernatural telepathic ability and instead use a NeuralInterface to gain this power. In this form of telepathy, thoughts are converted from impulses in the brain (electric activity produced by neuron reaction potentials) into digital signals that can then be broadcast artificially to another e-telepath using radio waves or some other form of wireless communication. Obviously, this can lead to MentalFusion or even a HiveMind, just as non-technological telepathy can.

This form of telepathy is different from others in that it does not allow MindReading, since a person must be actively transmitting a signal in order for another to receive it. However, it is possible for an enterprising cyborg to "mind hack" another user of an implant and monitor their thoughts without their permission, similar to infecting a computer with spyware.



[[folder:Anime & Manga]]
* In ''Anime/GhostInTheShell'' this is one of the many advantages of having a cyberbrain. Characters can communicate with each other without physically speaking, which is useful if you are trying to keep quiet to avoid detection or eavesdroppers. Of course, wirelessly broadcast connections are open to being spied on, so for very important conversations cyborgs sometimes directly connect to one another using cables. In one episode of ''Stand Alone Complex'', Batou and the Major even keep a conversation hidden from the Tachikomas by hiding their cyber-telepathic communication and using their actual lips to have a completely different conversation -- at the same time!
* This is how the MISAKA clones maintain their HiveMind in ''LightNovel/ACertainMagicalIndex'', using their inherent [[ShockAndAwe electricity-manipulation powers]] to act as living radio transceivers. While Mikoto (who they were cloned from) is theoretically able to do it as well since she is stronger and has far greater control than them, she doesn't have the proper training to be able to interface with the network.
* ''Anime/MobileSuitGundam'' and its many sequels has the Psycommu ("'''Psy'''chic '''Commu'''nicator") system, a machine designed to pick up the psychic emanations from Newtypes and use them as a means of communication. This allows a Newtype to control a properly equipped machine by thought alone, and is usually used to explain how the pilots are able to control the various kinds of AttackDrones.

[[folder:Comic Books]]
* ''ComicBook/TheAuthority'' uses "radiotelepathy", a communications network of nanoscale radio implants that allow brain-to-brain communication.
* In ''ComicBook/SupergirlRebirth'', the DEO develops a device which allows ComicBook/{{Supergirl}}'s mind to access Lar-On's comatose brain and find a way to heal his psychological damage.

[[folder:Films -- Live-Action]]
* ''Film/DemolitionMan'': In the future, people use this for having sex. The idea of doing it the normal way disgusts them (partly out of prudishness, and partly because there were apparently numerous additional HIV-type outbreaks in the intervening decades).

* In ''Literature/{{Animorphs}}'' the main characters can send thought messages when they're in morph. The cube that gave them the morphing power apparently gave them this as well.
* The soldiers in ''Literature/OldMansWar'' have a computer embedded in their brain which lets them do this.
* This form of telepathy is used in ''Literature/TheHistoryOfTheGalaxy'' novel series by [[TheCracker cybreakers]] to enter the mind of another person via implants that everyone has in their brains. They can read thoughts, conduct MindRape, and even fry the victim's brain. Actual [[PsychicPowers telepathy]] exists in this [[TheVerse 'verse]] but is natural only to the [[BugWar Insect]] race. Certain brain scanners are also able to translate EEG scans into roughly-approximated thoughts based on a chart developed for all humans.
* In ''Literature/HeartOfSteel'', Alistair Mechanus has a mental link with his robots and his computer network through his cybernetic implants.
* In ''Literature/{{MARZENA}}'', when entering Dr. Sam's mind thanks to drugs and Virtual Reality, Lauren and Kristen communicates with each other using digital telepathy, thanks to nanobots reading their brain activity by sending wireless signals when entering inside dilated brain vessels acting therefore like mini MRI machines.
* ''Literature/{{Eldraeverse}}'': The {{Precursors}} genetically engineered the [[SpaceElves eldrae]] to have organic radio transmitters in their brains.
* In ''Literature/AncillaryJustice'', this is used to link the cybernetic ancillaries to their ship’s HiveMind and used in a similar manner by the emporer, who is a HiveMind of linked clones. To a lesser extent, Radchaai ships and station can also use this to read the perceptions and emotions sent by implants in their human inhabitants, and ability Breq keeps from her time as a ship.
* In ''Literature/TheEmpressGame'', Dolan's speciality using technology to replicate, enhance, and deploy Wyrd telepathy. The things he did with it, though, caused him to be stripped of his own psi powers and exiled. [[spoiler:They didn't seem to consider that his technology might allow him to regain his powers]].
* In the short story "Tableau" by James White, one side in an interstellar war develops a "mentacom" device that allows a ship's crew to communicate mentally, after finding battle noise too disruptive to vocal communication. When two pilots, one from each side, end up marooned together after a battle, the mentacom makes it possible for them to communicate with each other and make the first steps toward a peace.
* ''Literature/RevelationSpaceSeries'' by Creator/AlastairReynolds: The Conjoiners have this. In an early war against unaltered humans, they would forcibly implant the equipment into their prisoners, who generally thought "I am everyone! I know everything! Awesome!"

[[folder:Live-Action TV]]
* The Borg in the various ''Franchise/StarTrek'' series have built-in "neural transceivers" to connect their minds into the Collective. Each Borg ship contains a device called a "vinculum" which transmits, receives and edits thoughts to and from connected Borg drones so as to suppress their individuality and direct them in performing their designated functions.
* In ''Series/Supergirl2015'' episode [[Recap/Supergirl2015S3E10LegionOfSuperHeroes "Legion of Super-Heroes"]], a piece of 31st century technology is used to allow Brainiac 5 to enter [[ComicBook/{{Supergirl}} Kara]]'s mind. He's even able to do that while far from Kara's physical location.
* In ''Series/{{Dollhouse}}'', the Rossum Corporation developed a breed of HiveMind-ed {{supersoldier}}s who communicated this way. However, the hive mind had a weakness in that [[spoiler: if someone else could tap into it, they could royally screw up the mental communication between soldiers.]]
* While being interrogated in the ''Series/DoctorWho'' series, "[[Recap/DoctorWhoS2E7TheSpaceMuseum The Space Museum]]", the Doctor is put up against a device that can transmit his thoughts onto a screen. The intent is to get answers based on what the Doctor thinks when asked a question, regardless of what he says out loud. It fails, as the Doctor just transmits images of random things such as an old-style big-wheeled bicycle when asked how he got there.
* ''Series/TheOuterLimits1995'': In the episode "Living Hell", a doctor saves a wounded man's life by implanting an experimental neutral transmitter in his brain. A side effect of this is that he can now see the thoughts of an elusive serial killer who was given the same implant and had faked his own death afterwards.

[[folder:Tabletop Games]]
* In ''TabletopGame/EclipsePhase'' most people have access to the setting's internet successor via implants that make telepathy about as common as talking. The fiction notes "mesh communication" via RainbowSpeak.
* ''TabletopGame/{{Mindjammer}}'' has a whole list of "technopsi" abilities that are used through the Mindscape.

[[folder:Web Comics]]
* It's never spelled out, but this appears to be how the Martians' collective consciousness works in ''Webcomic/AMiracleOfScience'': faster-than-light communications gear (which may or may not be the same thing as the radio communication demonstrated on numerous occasions) incorporated into the [[{{Nanomachines}} nanotech]] that suffuses their bodies.
* One of the "upgrades" that CORE soldiers in ''Webcomic/{{SSDD}}'' can get.
* Relays in ''Webcomic/AlienDice'' allow this.
* One of the relatively minor characters in ''Webcomic/SchlockMercenary'' is from a species that evolved a natural form of this, specifically an organic radio transmitter/receiver. The one shown has a single consciousness split across two bodies, and with a little added hardware to enable communication via [[SubspaceAnsible hyperspace nodes]] his range is extended to the point where he can pilot two separate tanks simultaneously with a level of tactical co-ordination that normally only an AI can manage.
* In ''Webcomic/AGirlAndHerFed'', Agents can communicate this way via their [[BrainComputerInterface implant]].

[[folder:Web Original]]
* ''Podcast/{{Limetown}}: The scientists in Limetown were trying to figure out how to do this.
* In ''Roleplay/DarwinsSoldiers'', Dragonstorm has an entire "thought network" which is exactly this. [[TheMole Mole]] Shelton brings some of the chips for the main characters to use.

[[folder:Western Animation]]
* The Mindnet device in ''WesternAnimation/AdventuresOfTheGalaxyRangers''. It was used mostly to crank up the abilities of existing psychics (The Queen and Niko), but was used by Nimrod during "Battle of the Bandits" to stupefy an audience already ensnared by ThePowerOfRock.
* In ''WesternAnimation/VoltronLegendaryDefender'' the five lions that form voltorn are explicitly said to be able to link with their pilot's minds allowing for more fluid control and the ability for the pilot to see through their lion's eyes.

[[folder:Real Life]]
* [[http://medicalxpress.com/news/2013-08-colleague-motions-human-brain-to-brain-interface.html Researchers were able to link two human brains together, enabling one person to control the other's arm.]]
