Strain Sensor

Manufacturer: Unknown Classification: Street-Grade Weave Detection Gear Primary Users: Flowborn, Patchrunners

Overview

The Strain Sensor was never approved, licensed, or announced.

It simply appeared.

Often jury-rigged, sometimes half-broken, the Strain Sensor is a street invention born of necessity. Those who walk the city’s vertical layers and forgotten corridors need to know where reality thins.

Function

The device passively scans for Strain Lines, areas where the Weave is under tension or distortion.

When active, it provides:

• Directional depth awareness (vertical and horizontal)

• Intermittent wave-signal feedback indicating Weave density

• Erratic interference near corners, tight alleys, or enclosed spaces

The city is not flat. The Strain Sensor was built for the city.

Limitations

• Signal degradation increases with distance

• Complex geometry causes false echoes

• Multiple overlapping Strain Lines can overload the device

Veteran Patchrunners learn to read its failures as much as its successes.

Lore and Myth

No one knows who made the first Strain Sensor.

Stories suggest:

• A fallen Weaver

• A MediTec prototype leak

• Or the city itself learning how to warn those who listen

Among Flowborn, finding a working Strain Sensor is considered a sign that the Weave wants you alive.
