More Information
Summary:Provided are a deformable fingerprint recognition device and a fingerprint authentication method and an electronic apparatus using the deformable fingerprint recognition device. The deformable fingerprint recognition device may include a fingerprint sensor configured to be deformed in shape and a strain sensor provided on a surface of the fingerprint sensor to measure deformation distribution of the fingerprint sensor. The deformable fingerprint recognition device may recognize a fingerprint of a user by reflecting the deformation distribution of the fingerprint sensor measured by the strain sensor. The deformable fingerprint recognition device may include a plurality of first pixel regions to detect the fingerprint of the user, and the strain sensor may include a plurality of second pixel regions to measure the deformation distribution of the fingerprint sensor.
