AI Technical Summary
In existing transcutaneous electrical stimulation devices, the current tends to concentrate locally, resulting in excessively high local current density, stinging sensation, and discomfort. Furthermore, it is difficult to achieve large-area uniform stimulation and control of the spatial current coverage area.
By employing a multi-zone electrode assembly on the body surface, a multi-path spatial return structure is formed through the spatial spacing, area configuration, and layout relationship of multiple conductive regions of the same polarity. Combined with an electrode assembly of opposite polarity, a distributed return path is formed, thereby changing the current distribution pattern.
It reduces local current concentration, improves the uniformity of current distribution, expands the effective electric field area, enhances comfort during long-term use, adapts to different body parts, and avoids local hot spots and stinging sensations.
