Multidirectional implanted flexible electronic device and preparation method thereof

Abstract

The invention provides a multidirectional implantable flexible electronic device and a preparation method thereof. The multidirectional implantable flexible electronic device comprises at least one composite magnetic film device and a column core connected with the composite magnetic film device, the composite magnetic film device with the self-defined magnetic field distribution is of a curly structure, and the curly structure is fixed through a water-soluble polymer or a fixing device. The composite magnetic film device comprises a magnetic film and a flexible electronic device attached to the magnetic film. After the implantable flexible electronic device is implanted into a preset area, the water-soluble polymer is hydrolyzed or the fixing device is opened, and the composite magnetic film device of the curly structure is released and completely unfolded to be of a tiled structure. The flexible electronic device can be implanted in a limited space, the application scene is expanded, multi-direction, multi-number and multi-functional devices can be synchronously implanted through a single small-diameter opening window, the implantation process is effectively simplified, and implantation risks caused by large-diameter and multi-number opening windows are avoided.

Description

technical field [0001] The present disclosure relates to the field of flexible circuits, in particular to a multi-directional implantable flexible electronic device based on a self-expanding model of a curled flexible magnetic film and a preparation method thereof. Background technique [0002] In the field of medical diagnosis and treatment, in addition to the traditional physical examination, that is, doctors use their senses (eyes, ears, nose, hands) or simple diagnostic tools (stethoscope, percussion hammer, etc.) Mature imaging diagnosis and treatment and blood biochemical testing are used as auxiliary means. The above-mentioned diagnosis and treatment methods are often concentrated on the body surface and are suitable for short-term information acquisition. The operation time is short and the ability to obtain information is limited. In many cases, some intuitive, continuous and long-term diagnosis and treatment methods are needed, such as long-term monitoring of EEG s...

Problems solved by technology

However, the existing interventional or implantable devices or devices are usually single-implanted, have a single function, and have a limited working area; most of the implanted device forms are suitable for cavity structures or organs with large spaces, and it is difficult to implant in areas with narrow spaces. , the shape of the existing implanted device is difficult to meet the demand, and it is easy to cause blockage and affect the original tissue function; multi-device implantation can only be realized through multiple opening windows, and the size of the opening window is strictly limited by the size of the implanted device
