Semiconductor firm Cypress has unveiled a fingerprint sensor solution for mobile devices at the Mobile World Congress 2015 which it has developed in conjunction with Norwegian manufacturer IDEX.Known as TrueTouch, the sensor uses proprietary sensing circuitry and a touch sensor design to improve fingerprint image quality and pattern matching accuracy.The FIDO-compliant sensor's design means that smartphone OEMs can create custom home buttons with specialized shapes and sizes or to integrate the sensor into any mobile device's industrial design or home button.”The barriers to entry are considerable in the emerging market for fingerprint readers, in part because of the highly specialized IP and complete solution that is required to compete,” said T.J. Rodgers, President and CEO of Cypress.”Our relationship with IDEX will enable us to provide our top-tier mobile customers with a globally deployable fingerprint sensing solution, including a sensor, Android drivers and a software stack.”Dr. Hemant Mardia, CEO of IDEX ASA, added: “We are extremely pleased with the performance of our new generation touch sensor developed in record time through our partnership with Cypress.” “This product has been designed based on fundamentally new technology to meet our OEM customers' demands for usability and security strength from small touch sensors.”IDEX is also showcasing a “unique” in-glass fingerprint sensor at Mobile World Congress in Barcelona.
