Abstract

The invention relates to the field of biomedicines and discloses an electrical stimulation system for promoting in vivo nerve repair. The electrical stimulation system comprises a nanogenerator, a wire and an electrode, wherein the nanogenerator is connected with the electrode through the wire to transmit current or voltage of the nanogenerator to the electrode; and the electrode can apply the current or voltage to an organism. The system for promoting in vivo nerve repair disclosed by the invention has the advantages that an electrical stimulation source is simple in structure, environment-friendly in materials, wide in material source, easy to be flexible and easy to miniaturize, and can be self-driven by motion and force of a body to generate electricity.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to an electrical stimulation system for promoting nerve repair in vivo. Background technique [0002] For regeneration after nerve injury, drugs, hormones and nerve growth factors are traditionally used to promote the repair of nerve cells and nerve tissue, but the effect is still not ideal. As a physical therapy, electrical stimulation can promote the regeneration of damaged nerves and prevent muscular atrophy, and its effect has been widely affirmed in the academic circles. There are currently two main stimulation methods for electrical stimulation: external electrical stimulation and implantable electrical stimulation. [0003] External electrical stimulation sources include various power sources and batteries powered by mains frequency, and implantable electrical stimulation sources are mainly batteries. The mains power supply is inconvenient to carry and depends on the mains supply...
