Abstract

An electronic device using a low frequency includes a belt, detachable electrode pads, and a control box that generates and controls stimulation signals. A cable within the belt includes a first line and a second line branching obliquely from a mid-portion of the first line at an angle of 30°-90°, forming a T-shaped configuration to supply independent frequency signals to the respective pads. Each pad is independently detachable from the belt for cleaning or replacement and includes Velcro disposed on both surfaces for reversible attachment. One surface of each pad may include a woven silver-plated conductive layer, and the opposite surface may include a carbon-based resistive heating film to provide combined electrical and thermal stimulation. The control box stores and executes instructions to automatically transition between multiple frequency signals according to predefined time intervals, thereby providing adaptive low-frequency stimulation for improved comfort and usability.
