| description | The present invention relates to composite piezoelectric apparatus, transducers and methods of manufacture. In an embodiment, a composite piezoelectric apparatus has a sacrificial base and pillar array. Different volume percents of piezoelectric material are used in the sacrificial base and pillar array. A first volume percent in the base is lower than the second volume percent in the pillar array. In this way, the sacrificial base can be easily removed from the pillar array after the base and pillar array are sintered in the manufacture of a final composite piezoelectric transducer. A method of manufacturing a composite piezoelectric transducer from a sacrificial base and pillar array and a composite piezoelectric transducer made by the method are provided. A composite piezoelectric transducer stack is provided. |
