Abstract
A biometric information sensor includes a first substrate and a first sensor electrode disposed on the first substrate. A second sensor electrode is disposed on the first substrate at a same distance from the first substrate as the first sensor electrode. The second sensor electrode is spaced apart from the first sensor electrode. A piezoelectric layer is disposed between the first sensor electrode and the second sensor electrode. A second substrate is disposed on the first sensor electrode, the second sensor electrode, and the piezoelectric layer.
