Abstract: Disclosed is a piezoelectric voice recognition sensor, which includes a flexible thin film, a piezoelectric material layer laminated on the flexible thin film, and an electrode laminated on the piezoelectric material layer, wherein the electrode includes a plurality of frequency separation channels arranged in a row, and the plurality of frequency separation channels have different lengths from each other. The piezoelectric voice recognition sensor separates a voice, recognized using a plurality of frequency separation channels having a trapezoidal shape, through the plurality of channels depending on frequencies, and simultaneously converts the separated voice signals from mechanical vibration signals into electric signals by means of the flexible piezoelectric element so that the converted electric signals are recognized.
