Pressure sensor and method of manufacturing the same

Abstract

A pressure sensor and method of manufacturing the same are provided. The pressure sensor includes a flexible sensor board. The flexible sensor board includes a dielectric layer, two circuit layers and piezoelectric sensing blocks. The dielectric layer has a first surface and a second surface opposite to the first surface. The two circuit layers are placed on the first surface and the second surface of the dielectric layer respectively. The piezoelectric sensing blocks are placed in dielectric layer and electrically connected with the two circuit layers. The mentioned pressure sensor utilizes the flexible sensor board that can be suitable for to the curvature of the diffident curved surfaces of the tested sample, which helps to improve the consistency and accuracy of the measurements.
