Embodiment

[0027] The specific preparation process of this embodiment is as follows: first deposit a 3 μm-5 μm polychlorinated p-xylylene (Parylene-C) film on the Si wafer, and then throw 0.01mm-1mm polydimethylsiloxane (PDMS), 80 Dry at ℃ for 4 hours to form the structure layer of the contact lens. Then throw 5μm positive resist and pattern it, sputter noble metal (including Pt, Ir, Au, etc.) seed layer, 100-15000 Angstroms, use Lift-off process to remove photoresist, pattern the seed layer, and form the electrode circuit layer. Then, throw 0.01mm-1mm PDMS, dry at 80°C for 4 hours, then deposit 3μm-5μm Parylene-C, pattern the photoresist for the second time, and use reactive ion etching (RIE) to remove Parylene-C Cut through to expose the electrode points that form the contact lens overlay. Finally, it is cut into the contact lens structure using a precision machine tool, and can also be molded into the contact lens structure.

[0028] Such as Figure 1-Figure 3 As shown, the contact...

Abstract

The invention discloses a contact lens type flexible microelectrode for recovery of facial paralysis in the technical field of medical appliances, comprising a contact lens structure layer, an electrode circuit layer and a contact lens covering layer which are orderly arranged to form a composite structure, and a through hole penetrating through the composite structure; the contact lens structurelayer is in direct contact with an eyeball; a connecting circuit and an electrode point connected with the connecting circuit are arranged outside the peripheral naked eye vision field of the electrode circuit layer. The contact lens type flexible microelectrode for recovery of facial paralysis is simple and convenient to operate, and by use of the same, a surgical operation is not required; and therefore, the contact lens type flexible microelectrode for recovery of facial paralysis is a solution capable of effectively solving the difficulty of closing orbicularis oculi muscle.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a contact lens 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 micro-electronic devices and micro-sensors has continued to expand, and has been widely used in many fields, especially in the medical field. . [0003] The orbicularis oculi muscle surrounds the eye and forms the eyelids, which are responsible for closing the eyes. By voluntary continuous contraction, the skin on it is pulled, and the eye-closing action is completed. Under normal circumstances, the orbicularis oculi muscle is innervated by the facial nerve, but if the facial nerve is damaged, the orbicularis oculi muscle will be paralyzed or paralyzed, unable to comp...
