This paper describes an engineering approach to avoid RF/microwave radiation in wearable EEG data transmission by using visible light communication. The system performance was tested at different illuminance levels and an algorithm for low-illuminance operation was proposed. The authors report error-free transmission…

This animal experimental study reports that low-intensity ultrahigh-frequency electromagnetic radiation and a low-intensity low-frequency magnetic field, applied after radiation exposure, enhanced metabolic and regenerative processes in rat testes and liver. The magnetic field was associated with increased…

This paper describes an in vitro gene transfection technique termed water-in-oil droplet electroporation, using an intense DC electric field to deform a droplet between electrodes. The deformation can cause an instantaneous short circuit, during which transient membrane pores are reported to form and permit exogenous…

This retrospective cohort study reviewed medical records from a Swedish tertiary pain centre to assess 1-month outcomes after pulsed radiofrequency for chronic non-cancer pain. Among patients receiving lumbar median branch pulsed radiofrequency, a minority had major or minor improvement, while many had no change and…

This materials study examined how growth rate and an external magnetic field affect microstructure and properties in directionally solidified Ag-Cu eutectic alloys. The lamellar spacing followed the Jackson-Hunt model with a reported constant of 5.8 µm³/s. Increasing magnetic field tilted eutectic growth and…

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…

This observational study examined whether passively collected smartphone GPS features relate to depressive symptom severity in 48 college students over 10 weeks. Several mobility features (including location variance, entropy, and circadian movement) were reported to correlate with PHQ-9 scores. Associations were…

This conference paper describes a peri-implantitis therapy using radio frequency electric current and presents numerical simulations alongside referenced clinical evidence. The abstract reports 81% successful treatment across 66 implants in 46 patients. FEM modeling suggests current preferentially concentrates in…

This engineering paper reports a prototype wearable patient-monitoring device that transmits vital-sign measurements via Bluetooth LE during MRI. Across 7 MRI acquisitions (25 minutes total), the authors report no Bluetooth packet loss, increased PPG noise during MRI, and no effect on temperature/humidity readings.…

This in-vitro study examined whether 50 Hz extremely low frequency electromagnetic fields affect proliferation in HeLa and CHO cell cultures. The abstract reports increased proliferation in exposed cells versus controls, with the largest reported increase under repetitive exposure at 2.49 mT (40 minutes every 12…

This computational study used finite element modeling to estimate the electric field distribution in the brain during tDCS for two electrode montages targeting the left DLPFC. It systematically varied isotropic tissue conductivity profiles to assess sensitivity of predicted E-field magnitude and components in the…

This conference paper reports an engineering approach to convert wireless microwave power into near-infrared light using a miniaturized, wirelessly powered laser. The device is described as millimeter-scale and capable of being powered through >1 cm of tissue. The abstract focuses on enabling in vivo activation of…

This conference paper describes the design and simulation of coil geometries intended to produce a highly uniform magnetic field for scleral search coil eye-movement recordings without restricting head motion. The authors built a large (2.2 m per side) coil frame and compared measured magnetic flux density to…

This engineering conference paper describes a method for controlling the locomotion of swallowable wireless capsule endoscopy devices using a dynamic magnetic field generated by external coils. A permanent magnet embedded in the capsule is manipulated by adjusting external field strengths to maintain equilibrium for…

This review assessed surgical and procedural case logbook smartphone applications available in major app stores. Of 2,740 apps screened, 16 were relevant and 11 were suitable for critical review, with reported variation in app size and cost. The authors conclude that current mobile apps can efficiently replace…

This study reports experimental measurements and numerical modeling of electric and magnetic fields near a high voltage substation in Annaba, Algeria. Field intensities were measured at multiple heights intended to correspond to sensitive human body regions and were validated using finite element simulations. The…

This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

This engineering study evaluates how anatomical/geometric differences affect MRI RF safety metrics. Simulations and a bovine-phantom experiment found that similar transmit B-field patterns can coincide with notably different peak SAR and temperature rise. The authors highlight challenges in using…
