Title:
WATERPROOF CASE FOR LOW-FREQUENCY ELECTRIC STIMULATION DEVICE, WATERPROOF-TYPE LOW-FREQUENCY ELECTRIC STIMULATION DEVICE, AND INSULATOR ELECTRODE FOR LOW-FREQUENCY ELECTRIC STIMULATION
Document Type and Number:
WIPO Patent Application WO/2019/225537
Kind Code:
A1
Abstract:
A low-frequency electric stimulation device conventionally uses an electroconductive electrode, and therefore cannot be used underwater or in a state in which skin is wet. Such a low-frequency electric stimulation device necessarily lacks a waterproof specification. Through the invention of a waterproof case having a terminal connection part and an insulator electrode for a low-frequency electric stimulation device, it is possible to use a low-frequency electric stimulation device during bathing. Through the invention of a waterproof bag having an insulator electrode film or an insulator electrode sheet for low-frequency electric stimulation, having an electrostatic capacitance of 0.36 nF/cm2 or greater, a cordless low-frequency electric stimulation device to which an energization permission sensor function or an underwater communication function is added can be used even underwater or in hot bath water. In the present invention, a waterproof-type low-frequency electric stimulation device is realized by adding a waterproof structure to a low-frequency electric stimulation device having a wireless charging function, an energization permission sensor function, an underwater communication function, or the like. In the present invention, a flexible insulator electrode film and insulator electrode for low-frequency electric stimulation are realized by dispersing 10-70 vol% of fine particles of an inorganic oxide having high relative permittivity in a resin.
