Silent Persistent Sensor Fabric creates living digital twins across every terrain and domain—without conventional RF pinging, routine battery replacement or an active transmitter heat signature

British Columbia (PRUnderground) July 13th, 2026

For decades, organizations have faced a fundamental trade-off: gain greater awareness by adding more sensors, or preserve operational simplicity, endurance and low observability by limiting them.

EPIC Semiconductors is working to eliminate that trade-off.

The company today introduced its Silent Persistent Sensor Fabric for Denied Environments, a semiconductor-based distributed intelligence architecture designed to create continuous, real-time digital twins across land, sea, air, space, underwater, underground and metal-dense environments.

The technology is designed to turn aircraft, ships, submarines, vehicles, buildings, machinery and critical infrastructure into systems that can continuously sense and understand their own condition—without behaving like conventional wireless sensor networks.

No conventional RF pinging. No active transmitter heat signature. All terrain. All domains. One living digital twin.

“The next strategic layer is not another radio, another battery or another isolated sensor,” said Nasrin Zadeh, CEO of EPIC Semiconductors. “It is a silent nervous system embedded throughout the physical world. When a platform can feel itself, understand itself and continuously update its own digital twin without announcing that it is sensing, the boundary between hardware and intelligence begins to disappear.”

The hidden cost of conventional awareness

Modern sensing systems typically depend on batteries, antennas, radio transmissions, wired connections and scheduled maintenance.

Every additional sensor can introduce new weight, installation cost, power requirements, communications traffic and failure points. In defence and security environments, conventional wireless activity can also make sensing infrastructure more electronically observable.

These limitations become more severe underwater, inside metal structures, within Faraday-cage-like environments, underground, in space and across remote terrain where batteries, wiring and conventional connectivity are difficult to maintain.

EPIC’s architecture is designed around a different assumption:

Sensing should become part of the platform—not an accessory attached to it.

Miniature semiconductor nodes can be distributed throughout an asset or environment, creating a coordinated sensing fabric rather than a collection of independent connected devices. The nodes gather and process local information, while gateways and analytics systems transform the combined data into a continuously updated operational model.

The result is a digital twin that can evolve with the physical system it represents.

From isolated measurements to a living digital twin

Traditional monitoring systems observe a small number of selected points. EPIC’s architecture is intended to make entire systems observable.

A Silent Persistent Sensor Fabric could support:

• structural and equipment-health monitoring;
• predictive maintenance and anomaly detection;
• temperature, pressure, motion, strain and environmental sensing;
• personnel, asset and condition awareness;
• sensing inside metal and composite structures;
• monitoring across underwater, underground and communications-denied environments;
• digital twins of aircraft, vessels, vehicles, infrastructure and industrial systems.

The strategic shift is from asking, “What does this individual sensor report?” to asking, “What is happening across the complete physical system?”

When large numbers of sensing points operate as one coordinated fabric, a ship can understand the behaviour of its structure, an aircraft can observe conditions within its airframe, and a facility can continuously map changes across equipment, personnel and environmental conditions.

A new category—not another wireless sensor network

The distributed-sensing landscape includes important technologies from companies such as Wiliot, Everactive, EnOcean, Impinj and Analog Devices, alongside ecosystems built around RFID, Bluetooth, LoRaWAN, industrial wireless mesh, fibre-optic sensing and conventional Internet of Things devices.These technologies have helped advance item-level identification, energy harvesting, smart buildings, industrial connectivity and lower-maintenance sensing. EPIC is pursuing a different architectural objective.

Rather than optimizing another conventional radio-connected endpoint, the Silent Persistent Sensor Fabric is designed for exceptionally low-observable, deeply embedded and high-density sensing in environments where traditional radios, batteries, antennas and wiring can become operational constraints.

The differentiation is not based on one feature alone. It is the proposed combination of:

Silent operation — without conventional RF beaconing or periodic pinging.

Low observability — without the active transmitter heat signature associated with continuously powered wireless nodes.

Persistence — designed to reduce dependence on routine battery replacement and maintenance.

High-density distribution — enabling sensing throughout a platform rather than only at a few instrumented locations.

All-terrain capability — suitable for remote, rugged, enclosed, submerged and infrastructure-dense environments.

All-domain operation — spanning land, sea, underwater, air, space and underground applications.

Digital-twin integration — allowing many sensing points to contribute to one continuously updated model.

EPIC addresses limitations that remain difficult for conventional sensing architectures to overcome simultaneously.

An enabling layer for the world’s most advanced platforms

The Silent Persistent Sensor Fabric is not intended to compete with complete aircraft, ships, autonomous systems, command networks or space platforms.

It is designed to become an enabling intelligence layer within them.

Global defence, aerospace and security organizations—including Lockheed Martin, RTX, Northrop Grumman, Boeing Defense, Space & Security, General Dynamics, HII, BAE Systems, L3Harris Technologies, Leidos, Airbus Defence and Space, Thales, Leonardo, Rheinmetall and Saab—continually evaluate technologies that can increase platform awareness, resilience, autonomy and operational endurance.

Across these organizations, the underlying challenge is increasingly similar: obtain more information from more locations without adding disproportionate batteries, wiring, maintenance, communications traffic, thermal activity or system complexity.

EPIC’s architecture could provide prime contractors, platform manufacturers and system integrators with a new embedded sensing layer for:

• real-time platform and structural digital twins;
• aircraft, ship, submarine and spacecraft health monitoring;
• autonomous and optionally crewed systems;
• contested logistics and asset awareness;
• undersea and underground operations;
• distributed sensing within metal structures;
• personnel and environmental awareness;
• predictive maintenance and operational decision support.

The technology may be integrated through licensing, application-specific silicon development, joint development programs or direct inclusion in future platform architectures.

“The world’s leading defence and aerospace companies already build extraordinarily capable platforms,” Zadeh said. “Our role is to give those platforms a silent and persistent nervous system—one that senses from within the structure, contributes to a real-time digital twin and operates across every terrain and domain.”

Changing the economics of intelligence

The implications extend beyond defence.

Aerospace, maritime, energy, infrastructure, manufacturing, transportation and remote-operations industries all face the same economic constraint: today’s sensing systems are often too expensive to install and maintain at the density required for a complete digital twin.

As a result, organizations monitor selected points and infer the condition of everything between them.

A persistent semiconductor sensor fabric could reverse that model.

Instead of deciding where an organization can afford to place a sensor, engineers could begin deciding where sensing should exist by default. Infrastructure could be born measurable. Equipment could carry its own operating history. Physical systems could continuously explain their condition to the digital environments responsible for managing them.

This represents a transition from the Internet of Things to something more fundamental:

an intelligent fabric embedded throughout the things themselves.

The future is not more visible sensors

The future of sensing will not be defined solely by higher bandwidth, longer range or larger batteries.

It will be defined by systems that can observe more while revealing less; operate longer while requiring less maintenance; and convert entire physical environments into continuously updated digital intelligence.

EPIC’s Silent Persistent Sensor Fabric is designed to make that future possible.

Invisible to conventional network assumptions. Persistent by architecture. All terrain. All domains. Digital-twin native.
