Title:
PRESSURE VISUALIZATION DEVICE AND MANUFACTURING METHOD THEREFOR, AND DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/179079
Kind Code:
A1
Abstract:
The present disclosure provides a pressure visualization device and a manufacturing method therefor, and a detection apparatus, relating to the technical field of detection. The pressure visualization device comprises a flexible substrate, a piezoelectric module and an electrochromic module which are located on one surface of the flexible substrate and are provided adjacently, a first attaching layer located on one surface, away from the flexible substrate, of the piezoelectric module, and a second attaching layer located on the other surface of the flexible substrate; the piezoelectric module comprises a plurality of piezoelectric units, and each of the piezoelectric units comprises a first electrode, a second electrode and a piezoelectric layer located between the first electrode and the second electrode; the electrochromic module comprises a plurality of electrochromic units, and each of the electrochromic units comprises a third electrode, a fourth electrode and an electrochromic layer located between the third electrode and the fourth electrode; and the second electrode and the third electrode are electrically connected, and the fourth electrode is a transparent electrode. The pressure visualization device in the present disclosure is delicate and portable and can instantly display a pressure signal curve.
