Document Type and Number:
WIPO Patent Application WO/2019/024444
Kind Code:
A1
Abstract:
A pressure sensor and a manufacturing method therefor. The pressure sensor comprises a light emitting element (01), an interference filtering structure (02), and a photosensitive element (03) which are stacked to each other. The light emitting element (01) is configured to emit incident light to the interference filtering structure (02); the interference filtering structure (02) is configured to change the thickness of the interference filtering structure (02) according to the pressure applied to the pressure sensor to form exit light corresponding to the pressure; and the photosensitive element (03) is configured to detect the exit light and form an electric signal corresponding to the exit light.
