Abstract:
There are provided a fingerprint detection sensor and a method of manufacturing the same. The fingerprint detection sensor includes a plurality of piezoelectric sensors arranged in an array on a two-dimensional plane and having a predetermined height; a filler provided to surround the plurality of piezoelectric sensors and isolating vibrations between the plurality of piezoelectric sensors; and a control unit discharging predetermined output signals through the piezoelectric sensors to detect information of an object in contact with, or close to, the plurality of piezoelectric sensors, wherein the plurality of piezoelectric sensors include first surfaces and second surfaces disposed on both ends thereof in a height direction and areas of the first surfaces and the second surfaces are different from each other.
