Abstract
The invention discloses a pressure sensor, a pressure detection method and a manufacturing process. The pressure sensor comprises an upper substrate, a lower substrate, a body circuit layer and extraction electrodes. The upper substrate and the lower substrate are prepared by elastic organic materials, wherein one side of the upper substrate and one side of the lower substrate are of a same three-dimensional structure, and are opposite; the body circuit layer is flexible, and is provided with a conductive line layer prepared by conductive materials; the body circuit layer is clamped between the upper substrate and the lower substrate, and covers the three-dimensional structures of the upper substrate and the lower substrate according to a function plane circuitous pattern substrate; two ends of the body circuit layer respectively lead out the extraction electrodes. According to the invention, base material stereoscopic deformation is generated through the force applied to the flexible substrate surface of the sensor, and meanwhile, the stereoscopic circuit structure in base materials forms stereoscopic deformation, and thereby resistance change is formed; according to resistance change, pressure values are calculated; the pressure sensor has the characteristics of simple structure, accurate measuring result and high sensitivity.
