The acoustic mirror has a Bragg reflector having λ/4-thick layers of different acoustic impedance. The topmost layer is made of silicon dioxide acting as an insulation layer in the mirror opening for electrically insulating the conductor track and the electrically conductive Bragg reflector layers. The arrangement is used as a physical transducer of a device for detecting a substance of a fluid, in particular of a fluid in the form of a liquid (biosensor)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Arrangement of a piezoacoustic resonator on an acoustic mirror of a substrate, method for producing the arrangement and use of the arrangement","description":"In an arrangement of at least one piezoacoustic resonator on a substrate surface, the resonator has an piezoelectric layer, an electrode and a further electrode arranged such that activation of the el","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8536764","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
