Abstract

The present disclosure provides a multi-directional implantable flexible electronic device and a manufacturing method thereof, wherein the multi-directional implantable flexible electronic device includes: at least one composite magnetic film device and a column core connected thereto; a composite magnetic film device with a custom magnetic field distribution The magnetic film device has a coiled structure, and the coiled structure is fixed by a water-soluble polymer or a fixing device; the composite magnetic film device includes: a magnetic film and a flexible electronic device attached to the magnetic film. After the implantable flexible electronic device is implanted in the predetermined area, the water-soluble polymer is hydrolyzed or the fixing device is opened, and the composite magnetic film device in a coiled structure is released and fully unfolded into a flat structure. The present disclosure can implant flexible electronic devices in a limited space, expands the application scene, and can simultaneously implant multi-directional, multi-quantity, and multi-functional devices through a single small-diameter opening window, effectively simplifying the implantation process, and avoiding problems caused by large apertures. , The risk of implantation caused by a large number of perforated windows.

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...
