It’s always prudent to consider safety first. I would break this into two parts:
1 - PEMF in general
2 - ICES-PEMF specifically
For PEMF in general, some of the larger “whole body” systems generate a lot of power, and this could be dissipated in the titanium implants by inductive coupling. These typically inefficient systems can radiate many Watts of power, so significant levels of heating of the implants is possible. It’s hard to say because it depends on a lot of factors, but it is definitely a possibility.
For ICES-PEMF, our technology is ultra-efficient. Our systems generate a maximum of about 1/3 Watt of power. This is absolutely not enough to cause a heating problem for a titanium implant. Any amount of heat that is generated, which would be very small, would be quickly dissipated away by the normal heat dissipation and distribution system for tissues within the body. It is my technical opinion that there is no risk of heating a metal implant to any level that would cause concern when using ICES-PEMF.
