Title:
INTEGRATED DETECTION SENSOR AND TOUCH SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/047063
Kind Code:
A1
Abstract:
An integrated detection sensor and a touch sensing device. The sensor comprises: a first structural body, a second structural body and a bonding layer; the first structural body comprising a first electrode, a second electrode, and a first flexible membrane disposed between the first electrode and the second electrode; the first flexible membrane having a pyroelectric effect and a piezoelectric effect, and the first electrode and the second electrode being disposed so as to output a mixed temperature and pressure detection signal; the second structural body comprising a third electrode, a fourth electrode, and a second flexible membrane disposed between the third electrode and the fourth electrode; the second flexible membrane having a piezoelectric effect, and the third electrode and the fourth electrode being disposed so as to output a pure pressure detection signal; the bonding layer being configured so as to insulate and connect the first structural body and the second structural body.
