The fingerprint sensing system is configured in such a way that the low potential and the high potential are variable while substantially maintaining the supply voltage, and the read-out circuitry is connectable to each of the sensing structures in such a way that a variation in the low potential and the high potential while substantially maintaining the supply voltage results in a change of the charge carried by a sensing structure connected to the read-out circuitry. The change in charge is indicative of a capacitive coupling between the sensing structure and the finger."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint sensing system and method","description":"A fingerprint sensing system comprises a sensor array with a plurality of sensing structures and read-out circuitry connectable to each of the sensing structures, and power supply circuitry arranged t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9672401","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.
