1. A pressure sensor, comprising:
a first sensing module, and a second sensing module located on said first sensing module;
said first sensing module comprising,
a first negative electrode;
a plurality of first support structures arranged at intervals on said first negative electrode;
a first flexible insulating layer arranged to cover an upper surface of each said plurality of first support structures; and
a plurality of first positive electrodes, each said first positive electrode being arranged at intervals on a lower surface of said first flexible insulating layer and distributed between said plurality of first support structures; and
said second sensing module comprising,
a second negative electrode disposed on said first flexible insulating layer;
a plurality of second support structures arranged at intervals on said second negative electrode;
a second flexible insulating layer arranged to cover an upper surface of each said plurality of second support structures;
a plurality of second positive electrodes arranged on a lower surface of said second flexible insulating layer at intervals and distributed between said plurality of second support structures; wherein
said plurality of first support structures are offset from said plurality of second support structures; and
said plurality of first support structures are located directly opposite to said plurality of second positive electrodes.
