Abstract
Provided is an operating number-counting piezoelectric dispenser including a piezoelectric pump dispensing a liquid by using a piezoelectric element as an actuator. According to the operating number-counting piezoelectric dispenser, damages to a piezoelectric actuator may be predicted and the piezoelectric actuator may be replaced before the damages are caused, thereby preventing process loss and defective products and improving productivity.
