Title:
METHOD FOR MANUFACTURING ARTIFICIAL OLFACTORY SYSTEM AND ARTIFICIAL OLFACTORY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/163998
Kind Code:
A1
Abstract:
Disclosed are a method for manufacturing an artificial olfactory system and an artificial olfactory system. The method comprises: transferring a sensor pattern to a piece of copper foil and photoetching pattern by means of a photoetching technique (S1); performing first etching to fabricate a sensing unit (S2); dissolving a photoresist (S3); pouring out polydimethylsiloxane, curing same, and after curing is completed, stripping the polydimethylsiloxane and the copper foil from a preset silicon plate (S4); performing second etching on the polydimethylsiloxane and the copper foil, so as to provide a space for a sensing material and a friction process (S5); uniformly synthesizing a layer of a polypyrrole derivative on the surface of the copper foil by means of an electrochemical method (S6); and evaporating a layer of copper on the polydimethylsiloxane as a sensing electrode using an electron beam evaporation coating technique (S7). By simulating the olfactory system of a mammal on the basis of the principle of friction power generation and the function of olfactory receptors, the recognition of different gas molecules is achieved. The present invention can generate electricity by itself without connecting to an external power supply, has a small volume and is easy to carry, can detect poisonous and harmful gases at any time and any place, and is applied in clinical practice.
