Modeling the interplay between myelin architecture and local electromagnetic fields

Research RF Safe Research Library Jan 1, 2025

This engineering/modeling study developed a 3D myelin microstructure model using finite element analysis and high-resolution imaging to simulate local electromagnetic field distributions. It reports that myelin architecture substantially shapes the distribution of electromagnetic fields across neural tissues. The…

Perspectives on terahertz honeybee sensing

Research RF Safe Research Library Jan 1, 2025

This paper describes measurements and simulations to support terahertz (THz) sensing of European honey bees for environmental monitoring. It reports dielectric characterization of bee body parts across 1–500 GHz, scattering-based validation of 3D-printed bee mockups, and THz imaging demonstrating detailed anatomical…

Human achromatic flickers and phosphenes thresholds under extremely low frequency electric stimulations

Research RF Safe Research Library Jan 1, 2025

This study estimated thresholds and locus for human phosphene perception during non-invasive transcranial alternating current stimulation at 20, 50, 60, and 100 Hz. Perception depended significantly on stimulation intensity, with the lowest threshold at 20 Hz and no reported phosphenes at 100 Hz. The authors report…

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

Research RF Safe Research Library Jan 1, 2025

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…

Energizing Healing with Electromagnetic Field Therapy in Musculoskeletal Disorders.

Research RF Safe Research Library Jan 1, 2024

This 2024 review discusses electromagnetic field (EMF) therapy, including pulsed EMFs (PEMFs), as a non-invasive approach for musculoskeletal disorders. It describes EMF therapy as safe and effective with no apparent side effects and suggests potential benefits via tissue repair stimulation, inflammation reduction,…

Electromagnetic Field Stimulation Therapy for Alzheimer's Disease.

Research RF Safe Research Library Jan 1, 2024

This review discusses repeated electromagnetic field stimulation (REMFS) as a potential non-invasive therapy for Alzheimer's disease. The abstract describes reported benefits in AD mice, including reduced beta-amyloid, prevention of neuronal death, halted disease progression, and improved memory without edema or…

Cellular Mechanisms of Electromagnetic Field in Traumatic Brain Injury.

Research RF Safe Research Library Jan 1, 2023

This paper reviews literature from 1980–2023 on the role of electromagnetic fields as a therapy for traumatic brain injury and brain neuropathology. It reports that existing findings suggest electromagnetic therapy may be a promising non-invasive treatment approach. The authors emphasize that current evidence is…

Measuring the Electromagnetic Field of the Human Brain at a Distance Using a Shielded Electromagnetic Field Channel.

Research RF Safe Research Library Jan 1, 2022

This study describes a non-contact, non-invasive method to measure electromagnetic activity attributed to the human brain using a lightweight helmet and a shielded EMF channel around a sensor. Volunteers performed metronome-synchronized tasks intended to elicit movement, thoughts of movement, and emotional thought.…

Measuring Electromagnetic Field Activity Generated by Neurons In Vivo by Humans With Thoughts of Repetitive Motor Activities and Emotional Thoughts.

Research RF Safe Research Library Jan 1, 2022

This study describes a helmet-based, non-contact method to continuously measure electromagnetic field activity associated with human brain neuronal activity during thought tasks. Volunteers performed motor movement, motor imagery, and emotional imagery while brain EMF was recorded. The authors report discernible…

Evaluating the Intrinsic Electromagnetic Field Generated by Neurons From Repetitive Motor Activities in Humans With a Non-contact Non-invasive Electromagnetic Helmet.

Research RF Safe Research Library Jan 1, 2022

This study reports a non-contact, non-invasive helmet system intended to measure intrinsic electromagnetic fields generated by the human brain during stereotyped motor tasks. Volunteers performed repetitive tapping, and the authors report discernible wave changes compared with rest and baseline measurements without a…

Novel Method of Electromagnetic Field Measurements of the Human Brain.

Research RF Safe Research Library Jan 1, 2022

This study describes a lightweight, inexpensive construct using non-contact EMF sensors to measure dynamic electromagnetic fields attributed to the human brain. Measurements in non-clinical volunteers reportedly differed from background recordings and changed during task performance and auditory stimulation. The…

Comparison of 2 methods of non-invasive treatment between transcutaneous electrical stimulation and pulsed electromagnetic field stimulation as replacement of invasive manual acupuncture.

Research RF Safe Research Library Jan 1, 2012

This study compared two non-invasive acupoint stimulation methods—TEAS and PEMF—as alternatives to manual acupuncture for recovery from exercise-induced muscle fatigue. Using 2 Hz stimulation (PEMF magnetic flux 30.92 mT), the authors report faster recovery of EMG median frequency and improved peak torque recovery in…
