Abstract
Provided is a piezoelectric property measuring apparatus for a liquid or viscous material. The piezoelectric property measuring apparatus includes a fixing jig having an inner space and an opened space; an operating jig configured to close the opened region of the inner space; a first electrode and a second electrode; a driving module moving the operating jig according to a driving signal; a motion information measuring module measuring motion information of the operating jig; a charge amount measuring module measuring the charge amount through the first electrode and the second electrode; and a control module generating the driving signal for the driving module, supplying the driving signal to the driving module, receiving the motion information, receiving charge amount information of the closed space, and measuring a piezoelectric property of the sample by using the motion information and the charge amount information.
