Embodiment

[0028] The specific preparation process of this embodiment is as follows: first deposit 3μm-5μm polychlorinated paraxylene (Parylene-C) film on the Si wafer, and then spin 0.01mm-1mm polydimethylsiloxane (PDMS), 80 Dry for 4 hours at ℃ to form the structural layer. Then, the 5μm positive glue is sputtered and patterned, and the seed layer of precious metals (including Pt, Ir, Au, etc.) is sputtered, 100-15000 angstroms, and the lift-off process is used to remove the photoresist and pattern the seed layer to form the electrode circuit layer. Then, shake the PDMS of 0.01mm-1mm, dry at 80℃ for 4 hours, then deposit Parylene-C of 3μm-5μm, pattern the photoresist for the second time, and use reactive ion etching (mE) to etch the Parylene-C Engrave through to expose the electrode points to form a covering layer.

[0029] Such as Figure 1-Figure 3 As shown, the movable denture type flexible microelectrode for facial paralysis rehabilitation prepared in this embodiment includes: a stru...

Abstract

The invention relates to a movable false tooth type flexible microelectrode applicable to facial paralysis rehabilitation in the technical field of medical apparatuses. The movable false tooth type flexible microelectrode comprises a structure layer, an electrode circuit layer, a covering layer and a through hole, wherein the structure layer, the electrode circuit layer and the covering layer are arranged in sequence to form a composite structure; the through hole penetrates through the composite structure; the covering layer is in direct contact with one side or two sides of a paralyzed facial muscle group in an oral cavity; a connection circuit and electrode points are arranged in the electrode circuit layer, wherein the connection circuit is covered by the covering layer and is electrically insulated; and the electrode points are exposed to realize electric stimulation. The flexible microelectrode additionally designed on the basis of a movable false tooth is simple and convenient to wear, needs no surgical operation, does not affect the facial appearance and is a solution for solving the difficult movement of the facial muscle group caused by facial paralysis.

Description

Technical field [0001] The invention relates to a device in the technical field of medical equipment, in particular to a movable denture type flexible microelectrode for facial paralysis rehabilitation. Background technique [0002] In recent years, with the continuous advancement of micro-electro-mechanical systems (MEMS: Micro-Electro-Mechanical Systems) technology, the application range of micro-systems such as microelectronic devices and micro-sensors has been continuously expanded, and has been widely used in many fields, especially in the medical field. . [0003] Facial paralysis is a common disease characterized by motor dysfunction of facial expression muscles. The general symptom is crooked mouth and eyes. The patient's face is often unable to complete the most basic movements such as raising eyebrows, closing eyes, and bulging mouths. The facial expression muscles of the disease are completely paralyzed, the forehead wrinkles disappear, the eye clefts are enlarged, the...
