Development of Four-Channel Magnetic Nerve Stimulator.

摘要

Magnetic nerve stimulants activate nervous systems by inducing electric fields inside the tissue. Due to their high power consumption and high voltage driving requirements, only single-channel nerve stimulation 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 multi- channel 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 stimulation such as nerve diagnoses or magnetic acupuncture therapy.
