Neuranics’ Ultra-Sensitive TMR Sensor Technology

Neuranics wants to redefine how we sense what the body is doing — without ever touching it. Their next-generation TMR sensor platform is small, contactless, and sensitive enough to detect pico-Tesla magnetic fields from muscles and the heart. That opens up huge potential for non-invasive wearables, gaming interfaces, and digital health monitoring.

What Is a TMR Sensor?

TMR stands for Tunneling Magnetoresistance, a quantum effect that changes resistance in response to magnetic flux. A TMR sensor can detect extremely small variations in magnetic fields—down to pico-Tesla levels. That’s more than enough to pick up signals from muscle contractions or a heartbeat, even through layers of clothing.

The paper ‘Wearable Super-Resolution Muscle-Machine Interfacing’ from The University of Glasgow, The University of Edinburgh, and Neuranics expands on the bio-electrical science making this breakthrough possible.

Neuranics’ sensors are a spin-out from the Universities of Glasgow and Edinburgh. They combine cutting-edge academic research with real-world commercial scalability. Their mission: move TMR sensor technology out of the lab and into products people actually use, particularly in the medical field.

Why Magnetic Sensing Beats Electrodes

Traditional biosensing methods like ECG require skin contact, sticky electrodes, or uncomfortable straps. A TMR sensor, on the other hand, picks up biomagnetic signals without needing direct skin contact. That means more comfortable long-term monitoring and simpler integration into everyday items like shirts, watches, or AR/VR headsets.

Rhianna Sweeny, Sales Engineer at Neuranics, explains that this non-invasive capability is a key differentiator. It reduces friction for users and opens doors for paediatric, wearable, and clinical use cases that previously relied on obtrusive hardware.

Engineered for Integration

Neuranics supports engineers from concept to production with full-stack development kits and customisable support. They’ve already begun proof-of-concept projects with Tier 1 companies across medical, gaming, and industrial domains.

Thanks to a background in advanced magnetics and sensor integration, Neuranics can also address challenges like signal noise and environmental interference. Their labs include magnetic shielding rooms for rigorous testing and dynamic range optimisation.

Ready to Evaluate?

Neuranics currently operates on a B2B model. They work closely with teams looking to integrate TMR sensor technology into real-world products. If you’re designing a wearable, a non-invasive health monitor, or an AR interface, this might be the sensor breakthrough you’ve been waiting for.
