Title:

SELF-POWERED HUMIDITY SENSOR, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/116355

Kind Code:

A1

Abstract:

A self-powered humidity sensor, and a preparation method therefor and the application thereof. The self-powered humidity sensor comprises a hydrophilic fiber membrane (1), wherein a transparent isolation layer (3) adheres to the back surface of the hydrophilic fiber membrane (1); two parallel conductive adhesive tapes (2) adhere to the front surface of the hydrophilic fiber membrane (1), and the conductive adhesive tapes (2) are taken as electrodes to be led out; and the hydrophilic fiber membrane (1) is soaked in a cobalt chloride solution and is dried. The preparation method is simple in terms of operation and low in terms of cost, and the self-powered humidity sensor prepared thereby can be applied in an environment with a wide humidity range, and has high humidity sensitivity.
