Piezoelectric disk resonators are designed to transduce specific contour mode bulk acoustic wave (BAW) resonant shapes. Utilizing a unique property of lead magnesium niobite-lead titanate (PMN-PT) thin films, microfabricated disk resonators are characterized using laser Doppler vibrometry. PMN-PT is a ferroelectric material that is known for its piezoelectric and electrostrictive properties.<\/p>","imageObject":{"variants":[{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_03c6c43f53.jpg.webp","type":"image\/webp","name":"default","width":"570","breakpoint":"1200"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_03c6c43f53.jpg","name":"default","width":"570","breakpoint":"1200"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_28f7b9110b.jpg.webp","type":"image\/webp","name":"large","width":"900","breakpoint":"992"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_28f7b9110b.jpg","name":"large","width":"900","breakpoint":"992"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_d692e8cb5f.jpg.webp","type":"image\/webp","name":"medium","width":"1380","breakpoint":"768"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_d692e8cb5f.jpg","name":"medium","width":"1380","breakpoint":"768"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_dedaa87359.jpg.webp","type":"image\/webp","name":"extrasmall","width":"640","breakpoint":"320"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_dedaa87359.jpg","name":"extrasmall","width":"640","breakpoint":"320"}],"default":{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/0\/9\/csm_piezo-materials-and-wine-glasses_03c6c43f53.jpg","alt":"","title":""}},"link":"https:\/\/magazine.polytec.com\/us\/what-you-always-wanted-to-know-about-piezo-materials-and-wine-glasses","origUid":7474,"readingTime":"4 min","subline":"What you always wanted to know about piezo materials and wine glasses","tags":[{"title":"Electronics, semicon, solar","uid":5},{"title":"General R&D","uid":6},{"title":"Materials research & NDT","uid":9},{"title":"Micro & nanotechnology","uid":10}],"technologies":[{"title":"Vibrometry","uid":214}],"title":"Single electrode transduction of contour modes in piezoelectric disk resonators","uid":7475,"visits":304},{"authors":[],"datetime":null,"description":"
