The present invention relates to a method a biological information recognition apparatus and a method for activating, by the biological information recognition apparatus, a recognition row and a recognition column including a plurality of piezoelectric elements in various patterns. More specifically, the present invention relates to a biological information recognition apparatus which may be used to identify a user by recognizing biological information, such as the fingerprint, blood vessels, and bones of the user and a method for driving the same. More specifically, the present invention relates to a methodology in which a plurality of recognition rows and recognition columns within the biological information recognition apparatus are activated according to a specific pattern and when each of the recognition rows or recognition columns is activated, biological information, such as the fingerprint, blood vessels, and bones of a user, is scanned in various patterns by selectively activating piezoelectric elements forming each recognition row or recognition column.

Biological information recognition apparatus and scanning method of the biological information recognition apparatus

The present invention relates to the lead-zirconate-titanate (PZT) amorphous alloy plating solution which may be used to form a PZT amorphous alloy film having excellent mechanical and physical properties and a method for plating a PZT amorphous alloy using the same. The PZT amorphous alloy plating solution may include a Pb precursor, a Zr precursor, and a Ti precursor. 10&#x2dc;50 parts by weight of the Zr precursor and 5&#x2dc;30 parts by weight of the Ti precursor may be included based on 100 parts by weight of the Pb precursor. Accordingly, electrical conductivity can be improved because the PZT amorphous alloy plating solution has a structure which has low crystallinity or which is amorphous. Furthermore, excellent electrical characteristics can be achieved because the PZT amorphous alloy plating solution has excellent conductivity or chemical stability.

The present invention relates to a biological information recognition apparatus and a method for selectively activating, by the biological information recognition apparatus, a plurality of piezoelectric elements. More particularly, the present invention relates to a biological information recognition apparatus which may be used to identify a user by recognizing biological information, such as the fingerprint, blood vessels, and bones of a finger of the user, and a method of driving the same. More specifically, the present invention relates to a methodology for individually activating a plurality of piezoelectric elements included in the biological information recognition apparatus and scanning biological information using a method different from a conventional method by selectively activating the plurality of piezoelectric elements. Furthermore, the present invention is directed to forming the piezoelectric elements on a substrate in a pattern of a form which is different from a conventional pattern of a matrix form and more efficiently identifying biological information.
