Abstract : A multiaxis transducer including a spherical conductive core, surrounded by a pair of piezoelectric hemispheres which are insulated from one another except at contact with the core. The piezoelectric hemispheres are surrounded by a pair of conductive hemispheres which are insulated from each other and are positioned to compress the piezoelectric hemispheres between the conductive hemispheres and the core so as to permit generation of electrical signals by the piezoelectric material through either compression or release of compression. Also included are means for receiving electrical signals generated by the piezoelectric hemispheres during application of acceleration force towards one of the conductive hemispheres. (Author)
