Abstract :
Magnetic nerve stimulators activate nervous systems by inducing electric fields Inside the tissue. Due to their high power consumptions and high voltage driving requirements, only single-channel nerve stimulations have been used for clinical or research purposes. In this paper, we introduce a four-channel magnetic nerve stimulation system. The system is composed of efficient high voltage charging circuitry with small size DC power supplies and multichannel controllers capable of driving magnetic coils with a variety of stimulation protocols. It is expected that the developed system can be used for many kinds of functional magnetic stimulations such as nerve diagnoses or magnetic acupuncture therapy.
