Abstract: The present invention relates to a pressure sensor, a pressure-sensor matrix array including the same, and a manufacturing method thereof, the pressure sensor including a first electrode, a conductive layer positioned on the first electrode and including a conductor, an active layer positioned on the conductive layer, being in contact with or being spaced apart from the conductive layer and including a polymer and a semiconductor dispersed in the polymer, and a second electrode positioned on the active layer. The pressure sensor and the pressure-sensor matrix array according to the present invention are capable of eliminating electrical crosstalk between pixels using a rectifying interface in a pressure sensor matrix having high sensitivity to resistance, thereby forming a high-resolution pressure sensor array, and moreover, processing costs and complexity are reduced, which is advantageous for industrial applications.
