Abstract:
Transcranial magnetic stimulation is widely used in clinical treatment and scientific research. It is facilitated through magnetic air coils, mostly built from copper high-frequency Litz wire. The magnetic stimulation coil induces a focused electrical field in the targeted tissue region of interest to trigger neuromodulation. The coil built-up, as well as its exact electrical properties, are important for the behavior of the triggered stimulation as well as the understanding of how to theoretically model and simulate such a system. This paper investigates the impedance behavior of two commercially available figure-of-eights shaped coils over a wide frequency range (up to 100 kHz) and compares the results to a custom-built round coil. All coils show similar electrical characteristics and, thus, these can be interchanged between stimulation devices without major adjustments. Moreover, the obtained results can be used for further theoretical investigations.
