The Ciliary Mesh Frond is a bio-synthetic mesh network node grown from Zheng-Dao's proprietary piezoelectric cilia substrate — a branching, fern-like structure roughly the size of a hand that adheres to most surfaces and begins passively harvesting micro-vibrations within minutes of deployment. These harvested vibrations are converted into carrier energy that powers a low-footprint, frequency-hopping mesh relay, capable of extending an encrypted network node into areas with no existing infrastructure. The Frond is literally alive in a limited sense: its cilia respond to environmental stimuli, adjusting their resonance frequency to optimize signal routing without active user input.

The device's distinctive property is its near-zero RF emission profile during idle states. Rather than broadcasting continuously, the Frond listens and responds — it activates only when a paired handshake signal passes within range, acting as a silent repeater that leaves almost no trace on passive spectrum scans. Its biological substrate also means it registers as organic matter on most bio-scanners, not electronics, which allows it to pass through checkpoints concealed in plant material, food packaging, or even worn against skin under loose clothing.

Zheng-Dao markets the Frond to corporate field teams for infrastructure-denied environments, but its properties have made it equally popular among resistance cells and insurgent networks in GLMZ's outer districts. The irony that a Zheng-Dao product underpins much of the anti-corporate mesh in the city's peripheral zones is not lost on anyone — least of all Zheng-Dao's internal security division, which has reportedly been trying to introduce a remote-kill pathway into newer production runs.
