The performances\u003c\/p\u003e\u003cp\u003eof transducers greatly rely on the properties of the piezoelectric\u003c\/p\u003e\u003cp\u003ematerials and transduction structures, including piezoelectric coefficient\u003c\/p\u003e\u003cp\u003e(\u003cem\u003ed\u003c\/em\u003e), electromechanical coupling coefficient (\u003cem\u003ek\u003c\/em\u003e), dielectric permittivity\u003c\/p\u003e\u003cp\u003e(\u003cem\u003ee\u003c\/em\u003e) and acoustic impedance (\u003cem\u003eZ\u003c\/em\u003e). Piezo-composite structures are\u003c\/p\u003e\u003cp\u003epreferred because of their relatively high electromechanical coupling\u003c\/p\u003e\u003cp\u003ecoefficient and low acoustic impedance. A number of piezo-composite\u003c\/p\u003e\u003cp\u003etechniques have been developed, namely “dice and fill”, “tape-casting”,\u003c\/p\u003e\u003cp\u003e“stack and bond”, “interdigital phase bonding”, “laser micromachining”\u003c\/p\u003e\u003cp\u003eand “micro-molding”. However, these techniques are either difficult to\u003c\/p\u003e\u003cp\u003eachieve fine features or not suitable for manufacturing of high frequency\u003c\/p\u003e\u003cp\u003eultrasound transducers (\u0026gt;20 MHz). The piezo-composite micromachined\u003c\/p\u003e\u003cp\u003eultrasound transducers (PC -MUT) technique discovered over\u003c\/p\u003e\u003cp\u003ethe last 10 years or so has demonstrated high performance high frequency\u003c\/p\u003e\u003cp\u003epiezo-composite ultrasound transducers.\u003c\/p\u003e\u003cp\u003eIn this monograph, piezoelectric materials used for high frequency\u003c\/p\u003e\u003cp\u003etransducers is introduced first. Next, the benefits and theory of piezo\u003c\/p\u003e\u003cp\u003ecomposites is presented, followed by the design criteria and fabrication\u003c\/p\u003e\u003cp\u003emethods. Biomedical applications using PC -MUT and arrays\u003c\/p\u003e\u003cp\u003ewill also be reported, in comparison with other ultrasound transducer\u003c\/p\u003e\u003cp\u003etechniques. The final part of this monograph describes challenges and\u003c\/p\u003e\u003cp\u003efuture perspectives of this technique for biomedical applications.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"ASME Press","offers":[{"title":"Default Title","offer_id":49952227164400,"sku":"9780791860441","price":99.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780791860441","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
