“…This is mainly due to the induction of eddy currents in metal implantable devices under RF fields [Sawicki et al, 2006;Ye et al, 2015]. Both the passive implants, such as vascular stents [Syrek et al, 2017], metal bar-implants [Miaskowski et al, 2016], hip and orthopedic implants [Kozlov et al, 2015;Miaskowski et al, 2012], prosthetic and dental implants [Safari et al, 2016], as well as the active implants like pacemakers and cardiac implantable devices [Gniadek-Olejniczak et al, 2018;Smondrk et al, 2018], deep brain stimulators [Guerin et al, 2019], etc., interact with the external EMFs produced by communication systems [Mat et al, 2017;Ye et al, 2015] or strong magnetic gradients generated by modern medical diagnostic tools such as magnetic resonance imaging (MRI) devices [Gniadek-Olejniczak et al, 2018;Yao et al, 2019]. Metal implants often prevent their patients from enjoying the benefits of modern civilization including MRI due to severe interactions with active implantable medical devices (AIMD) or discomfort feeling, pain and burning sensations [Zradzinski et al, 2019].…”

This paper discusses a new Implant Safety Tool, used to assess the safety of patients with metal implants exposed to radio-frequency (RF) fields. This specialist tool is discussed on the example of pectus patients with titanium bar-implant inserted during the minimally invasive Nuss procedure. The authors created a 3D realistic model of a 34-year-old male patient with a Nuss bar-implant. A numerical analysis based on the finite-difference time-domain (FDTD) method was performed for a far field source in the form of a plane wave with the frequency of 64 MHz, which corresponds to the RF exposure generated by MRI devices at 1.5 T. The obtained results allow concluding that the concave Nuss bar-implant poses no risk during environmental and occupational RF field exposures.

Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10 and 0.13 × 10 (W/kg) peak three-dimensional SAR at 2.4 and 5 GHz, respectively, which could be ignored in reference to standards and temperature rise due to laptop use.
