Validation of Electromagnetic Field Sensor Performance Through Porcine Skulls: Implications for Neurostimulation and Recording Techniques.

This animal validation study tested a Mu-metal-shielded helmet system with proprietary induction sensor stimulators for non-invasive recording and stimulation of neural electromagnetic activity through porcine skulls. The authors report that EMFs penetrated the swine skull and that sensor performance remained…

The Use of Induction Sensors and Helmet-Based Shielding Technology to Identify Differences in Electromagnetic Fields in Patients With Cranial Neurological Disease Versus Healthy Controls.

This observational study used induction sensors with a Mu-metal and copper mesh shielded helmet to measure cortically generated EMFs in patients with cranial neurological disease and compare patterns to previously obtained healthy control data. Fourteen patients (ages 14–81) were analyzed and compared with four…

A Swine Model of Changes in the Neuronal Electromagnetic Field After Traumatic Brain Injury: A Pilot Study.

This pilot swine study evaluated whether non-contact proprietary induction sensors in a Mu-metal/copper mesh helmet can measure endogenous neuronal EMF signals before and after controlled cortical impact traumatic brain injury. The authors report that swine EMF recordings were distinguishable from room noise and…

Measuring the Electromagnetic Field of Human Subjects Using Induction Sensors and a Shielded Helmet Without the Need for a Shielded Room.

This study evaluated whether a lightweight Mu-metal and copper mesh shielded helmet with EMF channels could reduce external electromagnetic interference enough to measure cortically generated EMF using non-contact induction sensors without a shielded room. In five volunteers performing motor, verbalization, and…
