The individual signals are connected internally at the sensor substrate in such a way that the response from the individual sensor elements can be separated from each other. Cross-talk is reduced by keeping the sensor outputs at a constant potential, thus eliminating the effect of capacitive coupling between different sensor outputs and also between sensor outputs and a ground or reference potential."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection method and apparatus for reduced cross-talk and asic area of a fingerprint sensor","description":"A method and apparatus for electrical detection of a finger print has a reduced number of interconnect signals between a sensor area and a substrate and an electronic circuit for excitation and detect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9625408","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.
