Tessera Industries Signal Cloaking Device SCD-1

A pocket-sized device that masks the electromagnetic emissions of the wearer's neural interface and all electronic devices within a 1-meter radius. The SCD-1 does not jam signals — it absorbs and contains them using a metamaterial shell, preventing any EM leakage that could be detected by passive surveillance. The device makes the wearer electronically invisible without disrupting their own device functionality — they can still use their neural interface and devices normally, but no emissions escape the containment field.

story hooks

An SCD-1 user walked through a total surveillance zone without triggering a single sensor — the only evidence of their passage was a person-shaped absence in the electromagnetic background.
A modified SCD-1 with expanded radius has been deployed in a meeting room, creating a permanently EM-silent space where no electronic surveillance can operate.

physical description

visual profile	A sleek cylindrical device resembling a premium vape pen or compact medical injector. The form is deliberately innocuous—designed to blend into everyday carry. The metamaterial shell creates an iridescent, oil-slick surface that seems to shift color depending on viewing angle, hinting at its EM-absorbing properties without advertising function.
dimensions	12 cm tall, 2.5 cm diameter—fits easily in a shirt pocket or jacket sleeve
weight description	Negligibly light (100g)—pocketable without noticeable burden, easily carried as daily wear
primary material	Metamaterial composite shell (proprietary Vasquez Biocompatible substrate) over a titanium-aluminum alloy skeleton
finish	Matte with microscopic lattice texture visible under close inspection; surface has an uncanny quality—light seems to be absorbed rather than reflected. No visible seams or ventilation ports.
color scheme	Gunmetal gray primary with oil-slick iridescence (purples, teals, sickly greens) that shifts in low light. Minimal accent lighting: a single dim amber LED ring near the base that pulses during active containment.
interface elements	Recessed capacitive touch panel on the upper third (unlock/activate); subtle haptic feedback system (no clicking). Micro-USB charging port recessed flush with the body. Status indicator: amber pulse = active, green steady = standby, red flash = low battery. No screen—entirely haptic interface.
distinctive features	Metamaterial shell exhibits visible light-absorption distortion—surrounding environment appears slightly warped when viewing the device directly Microscopic chevron patterns etched into the surface, barely visible but create a sense of engineered complexity The amber LED pulses in a rhythm that mimics a heartbeat—psychological reinforcement of 'living' invisibility Cooling fins are internal; exterior appears perfectly smooth but slightly warm to touch during operation
manufacturer markings	Embossed Φ symbol (QUANTA payment currency) and 'TESSERA INDUSTRIES' in minimalist sans-serif on the base. Tiny Vasquez Biocompatible Materials logo (stylized helix) laser-etched near the charging port. Regulatory stamps for GLMZ compliance discreetly applied to the underside.
condition typical	In active use, the device is warm (not hot) and the amber LED pulses steadily. The iridescent finish appears to 'drink' light from surrounding sources. Micro-condensation may form on the surface in humid conditions due to passive thermal management of the EM absorption process. User's neural interface HUD shows a persistent 'CLOAKED' indicator while active.

image prompt

Product photography of a pocket-sized cylindrical Signal Cloaking Device SCD-1, matte gunmetal with oil-slick iridescent sheen, resting on a sleek carbon-fiber workbench. The device casts an impossibly dark shadow—light seems absorbed by its metamaterial shell. Dramatic side-lighting reveals the microscopic surface texture and the faint amber LED pulse at the base. A neural interface HUD overlay visible in the upper corner displays 'CLOAKED | 7h 42m remaining'. Bokeh background of a cramped Tier 4 apartment: neon signs bleeding through rain-streaked windows, stacks of old electronics. Cinematic neo-noir lighting with deep shadows and cool color grading. --ar 3:2 --v 6
