A microgap between ten nanometers and 100 micrometers is established between the vibrating-electrode-insulating film (15a) and electret-insulating layer (14e). A central line average roughness Ra of the vibrating electrode (15b), including a bending, is 1/10 or less of a gap width measured between the bottom surface of the vibrating electrode (15b) and the top surface of the electret layer (13)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electro-mechanical transducer, an electro-mechanical converter, and manufacturing methods of the same","description":"An electro-mechanical transducer contains a vibrating electrode (15b), a vibrating-electrode-insulating film (15a) disposed at a bottom surface of the vibrating electrode (15b), an electret layer (13)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542852","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.
