Abstract

The invention discloses a platinum black pulse plating method based on ultrasonic assistance and belongs to the field of biomedicine engineering technology. The method comprises the steps of: vertically putting an electrode to be platinized and a platinum wire auxiliary electrode into an electroplate liquid and respectively connecting with the positive pole and the negative pole of a power supply; then applying pulse current and starting an ultrasonic device at the same time; and finally turning off the power supply and the ultrasonic device, taking the platinized electrode out and washing with deionized water to obtain a platinum black plating layer attached to the platinized electrode. The platinum black obtained by the invention can obtain greatly reduced particle diameter and better bonding force between the plating layer and a microelectrode substrate and is not easy to fall off to cause failure of the electrode; in addition, the platinized microelectrode obtains greatly reduced AC impedance and greatly increased electrode charge injection capacity and charge storage capacity, which is beneficial to the reduction of embedded system power consumption and the improvement of electric stimulus effect.

Description

Technical field [0001] The invention relates to a platinum black electroplating method in the technical field of biomedical engineering, in particular to a platinum black pulse electroplating method based on ultrasound assistance. Background technique [0002] The various movements of the human body are controlled by the movement of muscles, and the muscles are controlled by nerves through neuroelectricity. When nerves have obstacles such as nerve severance, nerve atrophy, etc., and muscles cannot be controlled, the movement of a certain part of the body cannot be achieved. Due to the piezoelectric properties of muscles, at present, the use of implanted microelectrodes to directly electrically stimulate the nerve-controlled muscles can produce certain deformations of the muscles, thereby controlling the movements of certain parts of the human body. Its applications include orbicularis oculi muscle stimulation to treat inability to close eyes, facial muscle stimulation to treat f...
