utarmes

Utarmes are a fictional class of compact energy storage modules used in speculative science fiction to power small autonomous devices. In most depictions, a utarme is roughly the size of a human fist, with a hard shell and a visible luminescent core. Internal chemistry combines a crystal lattice battery with solid-state switching and a tiny microcontroller, allowing controlled discharge and protection against fault conditions. Typical descriptions portray utarmes as durable, modular, and easy to swap between devices.

Function and operation: Utarmes store energy through a lattice of crystalline ions and regulate output via a microcontroller. They support rapid burst power for short tasks and sustained delivery for longer operations. Recharging methods include solar panels, kinetic harvesters, ambient thermal gradients, and wireless charging. Some models incorporate tamper resistance and self-diagnostic routines.

In-universe history and usage: The term appears in mid‑twenty‑second‑century techno-thrillers and has since become common in world-building for frontier technology. They are depicted as standard equipment for field technicians, explorers, and micro-robot swarms.

Etymology and status: The name utarme is presented as a fictional coinage; no real-world etymology is established. This article treats utarmes as a fictional concept created for illustrative purposes. See also energy storage device, portable power cell, micro-robots.
