Abstract
A nerve stimulator and a manufacturing method thereof. The nerve stimulator includes a glass substrate, and a plurality of metal pins provided on the substrate, wherein the metal pins form stimulation portions on one side of the substrate, and the density of the metal pins is greater than 15 Pin/mm2. The stimulation portions in the present nerve stimulator have a high density and a good stimulation effect. The processing method thereof is to cut out a high-density metal pin array first by using a metal underlayer, then the manufacturing method overcomes the deficiency in the prior art that it is rather difficult to manufacture a high density of nerve stimulation electrodes by using other substrates such as ceramics and the like.
