Abstract
Provided is a temperature-sensing piezoelectric dispenser, and more particularly, to a dispenser including a piezoelectric pump dispensing a liquid by using a piezoelectric element as an actuator. According to the temperature-sensing piezoelectric dispenser, a temperature of a piezoelectric actuator is measured and the piezoelectric actuator is cooled based on the measured temperature, thereby accurately controlling a liquid discharged according to an operation of the piezoelectric actuator.
