Abstract
The present application discloses an ultrasonic image sensor and a related electronic device. The ultrasonic image sensor is coupled to a sinusoidal pulse signal generating circuit. The ultrasonic image sensor and the sinusoidal pulse signal generating circuit are provided below a cover plate. The ultrasonic image sensor is used to sense a surface pattern of an object to be measured that makes contact with the cover plate from above the cover plate. The ultrasonic image sensor includes: an upper electrode; a lower electrode array; a piezoelectric layer, which is provided between the upper electrode and the lower electrode array, wherein the piezoelectric layer is excited by means of a sinusoidal pulse signal generated by the sinusoidal pulse signal generating circuit so as to generate an ultrasonic wave, the ultrasonic wave is transmitted along the cover plate to the object to be measured and then a reflected echo is generated.
