Space exploration missions in the future will involve in-situ sampling and analysis under extreme environmental conditions, so these missions will require actuators and sensors that can operate reliably for a long period of time under these conditions. Piezoelectric materials with very high Curie temperature would be ideal for this role, but there is very little information available about their electrical properties at elevated temperatures. A measurement system was developed in order to be able to measure the changes in the different vibration mode frequencies and electrical properties of...
