Description
| - The article describes experimental research on PZT ceramics used in knock sensors. The aim of the paper is to investigate the temperature effects related to the parameters of piezoelectric materials and to characterize the influence and changes exerted by these parameters on the properties of knock sensors. The material properties of such elements based on PZT ceramics are significantly affected by temperature changes; we therefore examined the temperature effect during the heating phase and analysed the subsequent permanent changes to the piezoelectric coefficients. In the experiment, emphasis was placed on investigating the piezoelectric coefficient changes up to the limit value (i.e., the Curie temperature): we determined the Curie temperature of the piezoelectric material used in the knock sensor, measured the impedance and phase characteristics at the given thermal value, and cooled the material down to the ambient temperature. Subsequently, the piezoelectric constants were calculated from these
