Method The electronic signs was humidified with normal saline, covered with fresh-keeping film, and then covered with gauze on the shaved mouse skin. Record the contact parts after 1, 24, 48 and 72 h. The electronic signs was injected subcutaneously into mice, and the mice were euthanized 24, 48 and 72 h after injection. The erythema and edema of the surrounding tissues were observed, and the tissues were examined pathologically. Result Electronic signs are not irritating to the skin. No abnormal surrounding tissue was found after subcutaneous injection. No abnormality was found in pathological examination. Conclusion No damage to mice was found by the electronic signs.
