Abstract
A pressure sensor comprises a first sensing module comprising a first negative electrode and first support structures arranged at intervals on the first negative electrode. A first flexible insulating layer covers an upper surface of the first support structures and first positive electrodes are arranged at intervals on a lower surface of the first flexible insulating layer and distributed between the first support structures. A second sensing module comprises a second negative electrode disposed on the first flexible insulating layer and second support structures are arranged at intervals on the second negative electrode. A second flexible insulating layer covers an upper surface of the second support structures. Second positive electrodes are arranged on a lower surface of the second flexible insulating layer at intervals and distributed between the second support structures. The first support structures are offset from the second support structures.
