The journal Scientific Reports has published an article by femu and co-authors entitled: “The role of the AC component in human perception of AC–DC hybrid electric fields”. The study was motivated by the newly introduced construction of both high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) overhead power lines mounted on the same pylon. The study is based on the previous publications of the femu (Jankowiak et al. 2021 and Kursawe et al. 2021).
The aim of the study was to specify the role of the AC component in the human perception of weak hybrid electric fields (co-exposure to alternating (AC) and static (DC) electric fields). Fifty-one participants with a hybrid EF detection ability above average who participated in a previous study were exposed under highly controlled. A further objective was to evaluate the influence of vibrotactile perception and skin moisture on EF perception.

The journal Environmental Health has published an article by femu and co-authors entitled: "Human detection thresholds of DC, AC, and hybrid electric fields: a double-blind study". The study was motivated by the newly introduced construction of both high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) overhead power lines mounted on the same mast. The study is based on the previous publication of the femu (Jankowiak et al. 2021).
The aim of the study was to determine the human detection thresholds for static (DC), alternating (AC), and hybrid electric fields (co-exposure to AC and DC EF; various DC EF strengths, constant AC EF strength). A total of 203 participants were exposed to DC, AC, and hybrid EFs in a highly specialized whole-body exposure laboratory using a double-blind experimental setting. The results indicated that detection thresholds of hybrid EF were lower compared to those of single EF exposure to DC or AC. Additional ion current exposure enhanced EF perception. High relative humidity facilitated DC EF perception, whereas low relative humidity reinforced the perception of AC EFs. With this systematic investigation of human perception of DC, AC, and hybrid EFs, detection thresholds were provided, which can help to improve the construction processes of energy transmission systems and the prevention of unwanted sensory perception.

The European Commission published a call for electromagnetic fields (EMF) and health research within the Horizon Europe Framework Programme (HORIZON). Research actions should provide forward-looking information on potential hazards and risks of existing and emerging EMF exposures. By applying innovative monitoring techniques, experimental evidence and modelling, several activities should be included, for example: monitoring of exposures of the general population and specific groups at risk such as children and workers, establishment of potentially new exposure patterns (e.g., 5G), and investigating evidence of local and systemic biological effects and health impacts.
Deadline for submission is 21st September 2021.

The journal Bioelectromagnetics has published an article by femu and co-authors entitled: "Identification of Environmental and Experimental Factors Influencing Human Perception of DC and AC Electric Fields”. As part of the energy transition in Germany, high-voltage direct current (HVDC) lines producing DC electric fields (EF) are in planning. Since the human perception of DC EF was rarely investigated in the past, the aim of the study was to investigate human perception of direct current (DC) EF, alternating current (AC) EF, and the co-exposure of DC EF and AC EF (hybrid EF). A highly sophisticated exposure lab was built to expose participants to various EF strengths and to control environmental and experimental factors influencing the human perception. Perception thresholds were lower under hybrid EF exposure than under DC EF or AC EF exposure alone. Relative humidity could be identified as an environmental factor influencing the perception of AC EF and DC EF in different ways. Cutaneous sensations evoked under DC EF and AC EF exposure were individually different and attributed to various parts of the body. Several environmental and experimental factors influencing the human perception of EF could be identified and provide an essential basis for a large-scale study.

The Journal Bioelectromagnetics has published a feasibility study conducted by the Institute of Medical Biostatistics, Epidemiology and Informatics (IMBEI) of the University Medical Center of the Johannes Gutenberg‐University in Mainz, Germany and femu entitled: "Occupational Exposure to Extremely Low‐Frequency Magnetic Fields and Risk of Amyotrophic Lateral Sclerosis: Results of a Feasibility Study for a Pooled Analysis of Original Data”. Previous meta‐analyses have suggested an increased risk of amyotrophic lateral sclerosis (ALS) associated with occupational exposure to extremely low‐frequency magnetic fields (ELF‐MF). However, since studies were methodologically heterogeneous, the feasibility of a pooling study to harmonize and re‐analyze available original data was investigated in this study. A relative risk of ≥1.14 for ALS and occupational exposure to ELF‐MF could be detected with a power of more than 80% in a pooled study. The pooling of original data was therefore recommended and could contribute to a better understanding of ELF‐MF in the etiology of ALS.

The journal Expert Review of Medical Devices has published an article by femu entitled: "Interference of Cardiovascular Implantable Electronic Devices by Static Electric and Magnetic Fields”. The aim of this study was to determine thresholds for electromagnetic interference (EMI) of cardiac implants by static electric and magnetic fields. A literature search revealed four interference mechanisms caused by static magnetic fields and none for static electric fields. Due to the scarce information on motion-induced EMI by static magnetic fields, numerical simulations were performed to obtain a threshold. The results showed that motion-induced EMI should not occur below the activation of the magnetic safety switch (MSS) at 0.8 mT. The authors concluded that MSS activation is the most relevant mechanism for static magnetic fields.

The journal Medical & Biological Engineering & Computing has published an article by femu and co-authors entitled: "Computational models for contact current dosimetry at frequencies below 1 MHz”. The aim of this study was to develop an extendable and adaptable validated numerical body model for computational contact current dosimetry for frequencies of 0 Hz – 1 MHz. Contact currents were conducted through the numerical body model Duke by seven contact electrodes on longitudinal and transversal paths. The resulting induced electric field and current enable the evaluation of the body impedance and the heart current factors for each frequency and current path to assess individual accident scenarios.

The Journal PLOS ONE has published a systematic review conducted by femu entitled: "Biological and health-related effects of weak static magnetic fields (≤ 1 mT) in humans and vertebrates: A systematic review”. The aim of this review was to systematically analyze and evaluate possible effects of weak static magnetic fields on biological functioning and to provide an update on the current state of research. Eleven studies fulfilled the eligibility criteria and were included in this review. All included studies were animal studies as no human studies were among the eligible articles. Overall, the available evidence from the literature reviewed is not sufficient to draw a conclusion for biological and health-related effects of weak static magnetic fields. We encourage further and more systematic research in this area. Any new studies should particularly address effects on biological functioning in humans to evaluate whether static magnetic fields pose a risk to human health.
The article can be found via the EMF-Portal, via PubMed and on the PLOS ONE homepage.
