To provide a sensor device manufactured using an organic semiconductor material.
Sensor cells are arranged in the form of an array within an organic semiconductor layer. A row and column selection circuit addresses one cell of the array at a time to determine the presence of an object contacting or located in proximity to a detection surface above each cell, e.g., the protruding or recessed part of a fingerprint. A control circuit can be provided inside either a companion silicon chip or a second layer made from an organic semiconductor material in order to communicate with the array and an associated system processor. The array consisting of the sensor cells can be manufactured using a flexible polymer substrate. The substrate is peeled and disposed of after contacts are patterned on the organic semiconductor layer. The organic semiconductor layer is usable together with a reactive interface layer which is made redundant to detect a specific chemical material in a test medium.
