[0002] After searching, the Chinese patent publication number is CN212592146U, and the publication date is 2021-02-26, which discloses a flexible microneedle dry electrode device for monitoring human electrical signals. The flexible microneedle dry electrode device for monitoring human electrical signals includes a flexible patch, a flexible microneedle dry electrode and a flexible printed circuit. The flexible microneedle dry electrode is arranged on the flexible patch, and the flexible microneedle dry electrode is electrically connected to the flexible printed circuit. The utility model ensures the flexibility of the overall device by arranging the flexible microneedle dry electrode on the flexible patch and electrically connecting it to the flexible printed circuit. It can be well attached to almost any skin surface, and the flexible microneedle dry electrode penetrates the high-impedance stratum corneum. In the absence of conductive gel or conductive paste, it can provide low impedance and stable electrical contact. The user can wear it for a long time and the activity is not restricted, which improves the applicability of various applications. However, when the device is not in use, since there is no protective measure on the outside of the device, the flexible microneedle dry electrodes and adhesive patches are in the air, which makes the flexible microneedle dry electrodes and adhesive patches easily contaminated. When the device is removed from the patient, the flexible patch is fully attached to the patient, and the flexible printed circuit may be easily damaged by pulling the flexible substrate, and the patient's skin may be easily damaged by buckling off the flexible substrate, making the device difficult to remove.
