Abstract

The invention discloses a zinc oxide nanowire electric generator based on myocardial cells and a preparing method thereof. An electric generator mechanism includes a substrate, wherein a groove is arranged on the substrate, an insulating tape is fixed on an opening of the groove, a plurality of zinc oxide seeding layers are deposited on the insulating tape at equal intervals, metal barrier layers are deposited on one side and the upper portion of the zinc oxide seeding layers, the zinc oxide nanowire horizontally arranged between the two adjacent metal barrier layers, one or more of the myocardial cells are arranged in the groove. According to the zinc oxide nanowire electric generator based on myocardial cells and the preparing method thereof, biological tissues (for example, myocardial cells) are used for driving the nanowire electric generator to perform power generation. The biological tissues, such as the myocardial cells and the like, has excited expansion function so that the external force is provided for the zinc oxide nanowire through an expansion process to drive the electric generator.

Description

technical field

[0001] The invention belongs to the field of nanogenerators, and in particular relates to a nanogenerator using cardiomyocytes as a driving source to generate electricity and a device structure of the nanogenerator. Background technique

[0002] Nanopiezoelectric materials, such as GaN and ZnO, have a wide range of applications in the field of nanogenerators and piezoelectronic devices. ZnO nanowires are currently the most studied piezoelectric materials in the world.

[0003] The zinc positive ions and oxygen negative ions in the zinc oxide nanowires are aligned in a positive tetrahedral structure, and without external force, the positive charge center of zinc ions coincides with the negative charge center of oxygen ions, and the dipole moment is zero. Under the action of external force, the zinc ions and oxygen ions deviate from the original position, the positive charge center and the negative charge center no longer coincide, and the dipole moment is not...
