MagTag is a passive, wireless sensor technology designed for environments where traditional RFID, Bluetooth, and battery-powered sensors are limited by interference, cost, or maintenance constraints. Developed in collaboration with Sandia National Laboratories and Los Alamos National Laboratory, MagTag uses magnetic resonance principles to provide reliable asset identification and environmental sensing in the most demanding conditions.

MagTag operates without batteries or active electronics. Instead, it uses arrays of micromachined magnetostrictive resonators that vibrate at unique, precisely tuned frequencies when exposed to an externally applied magnetic field. These resonant signals are wirelessly detected by a nearby reader system, enabling:

Requires no batteries, wiring, or onboard power, reducing cost and enabling long-term deployments across multiple locations.

Operates in low-frequency magnetic domains, maintaining performance in metallic, shielded, or cluttered environments where RF-based tags fail.
Each tag’s resonator geometry is microfabricated and non-reproducible, making duplication or spoofing highly impractical.
Unique frequency-domain encoding enables the simultaneous reading of multiple tags within a shared sensing space.
With no active circuits or memory, MagTag is intrinsically resistant to radiation, making it ideal for nuclear and high-energy environments.
MagTag is engineered for integration into a wide range of use cases, including:
Long-term UID tagging in radiation-exposed containers
Real-time leak detection using Pd-functionalized resonators
Long-term UID tagging in radiation-exposed containers

Sensing of gas leaks, thermal changes, or structural integrity without intrusive sensors or power requirements
Detection of fault currents and grid anomalies using resonant magnetic coupling
MagTag tags can be tailored for specific frequency profiles, environmental sensitivities, and mechanical form factors. The platform supports integration with external antennas, microcontroller-based readers, and cloud-connected IoT gateways. VastVision’s engineering team provides custom design, fabrication, and software support to deploy MagTag into your unique operational context.
