Abstract:
1. A wireless electrical stimulating device for living body, comprising: a light source unit for irradiating an optical signal; a light source control unit for controlling the optical signal irradiated from the light source unit; and an electrical stimulating unit for converting the optical signal received from the light source unit into an electrical signal to generate electrical stimulation, wherein: the light source unit comprises a plurality of LED lines parallel with each other; each of the plurality of LED lines has a plurality of infrared LEDs spaced apart from each other at regular intervals; first and second LED lines among the plurality of LED lines are adjacent to each other; and a first infrared LED in the first LED line and a second infrared LED in the second LED line, which is closest to a vertical line drawn from the first infrared LED to a straight line formed by connecting the centers of a plurality of infrared LEDs in the second LED line, are disposed such that the angle made by the straight line obtained by connecting the centers of the first and second infrared LEDs and the straight line formed by connecting the centers of the plurality of infrared LEDs in the second LED line is 60 degrees.
