Abstract

The present invention provides a self-driven electrical stimulation system, a band-aid, a cancer cell inhibition capsule, and a portable electrical stimulation system. The self-driven electrical stimulation system comprises: a triboelectric nano-generator is used for converting external mechanical energy into electrical energy; a cell culture medium comprises cells to be stimulated, the cell culture medium is connected by electrodes to the circuit of the triboelectric nano-generator; and a rheostat is connected to the circuit and is used for adjusting the magnitude of current in the circuit byadjusting the magnitude of resistance, thereby promoting or inhibiting proliferation and migration of the cells to be stimulated. In the scheme of the invention, under the current stimulation of 10-75 [mu]A, the output of the triboelectric nano-generator is applied to mouse fibroblast, and the triboelectric nano-generator significantly enhances the proliferation and cross-scratch migration of themouse fibroblast during the wound healing process. Moreover, the current stimulation greater than 75 [mu]A or greater than 100 [mu]A can also be applied to inhibit proliferation and migration of thecells to be stimulated.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a self-driven electrical stimulation system, a wound-protecting adhesive tape, a cancer cell suppression capsule and a portable electrical stimulation system. Background technique [0002] Bioelectricity is a basic property of life activities. Bioelectrical signals will appear in all life activities of organisms. For example, potential differences can be observed during the development of the neural tube, at sites of injury in epithelial cells, and on the surface of tumor cells. The resulting endogenous bioelectric field not only plays an important role in biological morphogenesis and growth, but also participates in important pathological processes of the body such as wound healing and tissue regeneration. [0003] Therefore, the study of electrical stimulation, especially the part that stimulates cells, is of great significance to the development of biomedicine. Compared...
