A photoelectric combined stimulation apparatus and method for a nerve. The apparatus comprises a control device that is composed of an electroencephalogram signal collecting and sending apparatus (1), a power source, a control instruction sending antenna (4), a stimulation parameter programmer, a processor (2) and a signal receiving apparatus, and a stimulation device that is composed of a signal receiving apparatus, a pulse generator (3) and a hydrogel stimulation electrode (5). The method is a photoelectric combined stimulation manner based on electroencephalogram signals. By means of adjusting electrical stimulation to be in a sub-threshold stimulation state, and then using high selectivity of photostimulation, not only can a target nerve be accurately stimulated, but energy during a single instance of photostimulation can also be reduced, thereby finally achieving safe stimulation with high selectivity. When an electrode is designed, by means of the biocompatibility and light-guide and electricity-conducting characteristics of the hydrogel electrode (5), a hydrogel material is made into a flexible electrode which is capable of guiding light and conducting electricity, such that biocompatible long-term safe stimulation can be realized.
