Title:
CAPACITIVE FLEXIBLE TACTILE SENSOR BASED ON GRADED INCLINED MICRO-CYLINDRICAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/065540
Kind Code:
A1
Abstract:
A capacitive flexible tactile sensor based on a graded inclined micro-cylindrical structure, the sensor comprising an upper electrode layer (1), a lower electrode layer (2), and a dielectric layer located between the upper electrode layer (1) and the lower electrode layer (2), wherein the dielectric layer is composed of an upper dielectric layer (31) and a lower dielectric layer (32); the upper dielectric layer (31) comprises an upper dielectric layer substrate (311), an upper dielectric layer long micro-cylinder (312), and an upper dielectric layer short micro-cylinder (313); the lower dielectric layer (32) comprises a lower dielectric layer substrate (321), a lower dielectric layer long micro-cylinder (322), and a lower dielectric layer short micro-cylinder (323); the upper dielectric layer long micro-cylinder (312) and the lower dielectric layer long micro-cylinder (322) are tightly bonded; and there is a distance between the upper dielectric layer short micro-cylinder (313) and the lower dielectric layer short micro-cylinder (323). The sensor has a stable structure, a viscous effect is overcome, and the dielectric layer is easier to bend and deform, so that the sensor has higher sensitivity, a shorter response/recovery time, lower hysteresis, and better stability.
