Exposure system sXcTEM27 for cell-line exposure to 27 MHz amplitude modulated radiofrequency fields.
The sXv27 system is designed to expose 2 × 8 cages with 2 mice each to 27 MHz RF signals.
The sXhS900 exposure system allows overnight exposure of the subject using a polarized antenna mounted above the volunteers bed.
On request we develop in vitro, in vivo or human provocation exposure systems, optimized for the specific electromagnetic exposure of interest to the customer.
|Expertise & Infrastructure
The IT'IS Foundation designs and builds electromagnetic field (EMF) exposure systems (sX series, where sX stands for "System for eXposure") with options for cells (c), vertebrates (v), and humans (h). As the world's premier provider of these systems, IT'IS offers its long-standing experience in the generation, fine control, and dosimetric evaluation of electromagnetic fields over a wide dynamic range and a variety of signals complying with relevant industry specifications, e.g. cell phone modulations. Our system design ensures maximum homogeneity and supports continuous monitoring of device conditions and environmental parameters, as well as blinded protocols.
Exposure system designs are tuned and validated through both numerical simulations as well as characterization measurements. The group’s exposure assessment laboratories are equipped with the most advanced tools including the latest DASY6 RX90L with DASY52NEO licenses, and a wide range of standard as well as specialized dosimetric probes. With more than 100 SemCAD/Sim4Life licenses, including the Virtual Population 3.x and multiple animal models, and several High Performance Computers (HPC) ranging from Graphics Processing Unit (GPU) clusters to supercomputers, our experienced team ensures that the exposure systems operate correctly and reliably.

|Supporting Science-based EMF Regulation
While many of the effects of EMF on living tissue remain poorly understood, the range of EMF applications in wireless communication and wireless power transfer is constantly expanding, as are the medical applications of EMF in imaging methods as well as therapies. As EMF regulations develop, it is crucial to protect higher-risk populations, such as small children or patients with medical implants, without resorting to overly conservative risk estimates which stifle innovation and technological progress. To understand the health effects of EMF, to develop the tools to study these effects, and to work with academia, industry and regulators to apply EMF safely and beneficially, are the core mandate of IT'IS.
We look forward to discussing with you how we can best support your research initiatives. We also provide support and consultancy services to streamline the application process of CTI co-financed R&D projects for the Swiss industry and to build effective consortiums for co-financed projects in Asia, the EU and US.
