Ihlets

Ihlets are a term used in speculative fiction and some theoretical discourse to denote tiny, self-contained agents designed to perform simple tasks. Depending on the context, ihlets may be described as artificial nanodevices, synthetic organisms, or hybrid systems. In most depictions, ihlets operate autonomously or semi-autonomously, and they communicate through simple signals to coordinate actions within a swarm.

Originating term: The coinage of ihlet is uncertain; early uses appear in online glossaries around the late 2000s and in science fiction anthologies, where they are presented as modular agents. Some writers distinguish ihlets by their compact size, typically millimeter scale, and their power sources, which may be ambient energy harvesters or micro-batteries.

Characteristics: Ihlets are described as having limited computational capacity, short-range communication, and modular payloads. They are designed for swarm behavior: local interactions lead to emergent group-level function. They may be designed to be biocompatible or non-biological, depending on author.

Applications and roles: In fiction, ihlets are used for environmental monitoring, search and rescue simulations, data collection in hazardous environments, or remote sensing. Ethical considerations include privacy and ecological impact; authors often address governance, consent, and containment.

Variants and examples: Some depictions include scout ihlets that map terrain, repair ihlets that perform micro-repair tasks, and bioluminescent ihlets used for signaling. Real-world analogies are found in swarm robotics, nanotechnology, and distributed sensor networks.
