Problems solved by technology

However, this kind of TENG is made of rigid materials, which limits its tensile properties, and cannot be folded multiple times or undergo complex deformations, which will seriously affect the development and research of energy materials in the new wearable field.
In addition, in practical applications, this kind of nanogenerator is connected with flexible deformable devices. Due to the mismatch of Young's modulus, there is a problem of unstable bonding at the junction of rigid materials and flexible materials.

Abstract

The invention relates to a deformable flexible nano generator, a manufacturing method and a manufactured sensor. The deformable flexible nano generator provided by the invention comprises a flexible packaging structure and an electrode embedded in the flexible packaging structure, wherein the electrode is a pattern electrode formed by gathering of a nano conductive material; and the flexible packaging structure adopts a tensile elastic packaging material. The flexible nano generator of the invention is tensile and deformable in a two-axis direction and can be attached to the surface of a regular or irregular object to work. The technical scheme of the invention can enable the flexible nano generator to be deformable such as tension, folding and torsion and to bear great mechanical deformation and damage to continue to work.

Description

technical field [0001] The invention mainly relates to the field of generators, in particular to a deformable flexible nanometer generator, a preparation method and a manufactured sensor. Background technique [0002] Since 2012, the nanogenerator system based on the electrostatic induction friction effect has been widely researched and developed, and some efficient, stable and mature devices and technologies have been gradually developed, providing a new way of thinking and guidance for new energy sources. However, since this kind of generator needs to be in contact with or rubbed with other materials to work, the current device of the triboelectric nanogenerator is mainly a rigid structure, which cannot be bent, stretched or deformed at will. This feature inevitably limits the application of nanogenerators, making them unable to be widely implemented on irregular objects or in wearable fields. [0003] Electronic components with special deformation capabilities, such as e...
