This exposure assessment study introduces a cost-efficient add-on sensor attached to a smartphone to quantify auto-induced uplink RF-EMF transmission across 100–6000 MHz in multiple microenvironments. Activity-based surveys were conducted in seven European countries under non-user, maximum downlink, and maximum…

This study examined prokaryotic DNA methylation (6mA and 4mC) and transcriptomes under different intensities of extremely low-frequency electromagnetic field (ELF-EMF) exposure. It reports motif-specific 6mA at 5'-GTACAG-3' and ELF-EMF-intensity-associated changes in spatial relationships among other 6mA sites,…

This animal study used non-contact induction sensors and a shielded helmet to measure cortical EMF patterns in a Yucatan miniswine before and after traumatic brain injury induced by controlled cortical impact. The authors report that targeted low-frequency EMF stimulation initiated 20 minutes post-injury was…

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…

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…

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.…

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…

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…

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…

This paper presents an in vitro, noncontact solenoid-coil device designed to deliver intermediate-frequency induced electromagnetic fields that generate electric fields in cell and tissue cultures. The system aims to improve field characterization and reduce conductive heating compared with electrode-based approaches…

This experimental study examined electromagnetic radiation (EMR) emitted by coal rock with prefabricated cracks during mechanical loading. The authors report that intact rock EMR increased with loading, whereas cracked rock EMR showed staged and fluctuating behavior that became more pronounced as crack angle…

This chart review describes four cases where stereotactic marking and excision were used to remove nonpalpable colorectal liver metastases during hepatic metastasectomy, guided by intraoperative ultrasound. Intraoperative ultrasound identified an additional lesion in one patient, and all resections achieved negative…

This engineering-focused paper reports the design principle and performance of a MALDI ion source ("MALDI-2") combining rarefied supersonic gas jets with weak electric fields and injection into gas-filled RF multipoles. The abstract reports rapid collisional cooling (

This paper describes an engineering application of electromagnetic field (EMF) treatment to mitigate biofouling in seawater-cooled tubular heat exchanger-condensers. After allowing a biofilm to stabilize, EMF treatment was applied and was reported to precipitate dissolved ions and contribute to partial…

This engineering study describes an experimental setup using a small electret condenser microphone connected to a notebook/PC to detect extremely low frequency signals. Using a small air cell made from a drilled DVD plate with a speaker and microphone on opposite sides, the microphone captured signals in the 0.5–20…

This experimental and modeling study examined pulsed electric field (PEF) permeabilization in several fruit and vegetable tissues at 293 K using 1000 μs pulses and field strengths of 400 and 1000 V·cm(-1). While electroporation theory predicts greater damage in tissues with larger cells, the authors report this…

This engineering/food science study examined ohmic heating of peaches at 60 V/cm using bipolar pulses across frequencies from 50 Hz to 1 MHz. Heating time to a target temperature and multiple electrical properties were frequency-dependent, particularly for intact tissue. The authors report faster electro-thermal…

This engineering-focused study measured ultrasonic propagation velocity in hydrocarbon-based magnetic and magnetorheological fluids under an external magnetic field. The authors report that clustering structures formed in the fluids influence ultrasonic propagation velocity, with observed hysteresis and anisotropy.…

This engineering-focused study examines failure of needle-shaped specimens exposed to very high electric fields in field-ion microscopy. The authors report experiments indicating breakdown may be initiated by nanoparticles detached from a point anode. They propose a mechanism in which expanding cathode plasma…

This critical review summarizes human research on static magnetic field (SMF) therapy delivered by permanent magnets attached to the skin and evaluates how well studies report SMF dosage and treatment parameters. Across 56 included studies, many did not report essential SMF characteristics (e.g., magnet dimensions,…
