A Device for Transcutaneous Stimulation of the Diaphragm.

Results obtained during the development of an original device for noninvasive transcutaneous stimulation of the diaphragm using electromagnetic radiation in the terahertz frequency range are presented. The block diagram and design of a terahertz emitter and a controlled current source for its power supply are presented, along with specialized software for selecting and setting the amplitude and time parameters of the stimulating signal.
