Technical Field

The invention relates to a weak electric stimulation device, in particular to an electric stimulation treatment electrode device with a hair growth function.

Background

Alternating Current (AC) electrical pulses can be used to stimulate the proliferation and growth of hair follicles, thereby promoting hair regrowth. In order to provide effective electrical stimulation, an alternating electric field needs to be applied uniformly to the scalp surface. Generally, an alternating electric field can be generated between a pair of interdigitated electrodes by providing an alternating voltage signal to the pair of electrodes. The alternating voltage signal can be generated by a wearable small device called a nanogenerator, which converts random mechanical motion into voltage pulses. However, the electric field generated by the electrode is reduced along with the increase of the distance, and the existing electrode design is difficult to be accurately attached to the head, so that the hair growth effect is difficult to be improved while the electric field is effectively increased; therefore, the situation that the electric field is enhanced and the hair growth effect is not ideal after the electrode is designed is caused; in addition, the existing flexible electronic product, such as a flexible circuit, can only deflect along one direction, and cannot generate a surface which is smooth and non-overlapping after being bent, so that the close fitting with the head is difficult to achieve, and the hair growth effect is difficult to improve accordingly.
