FlexEnable, ISORG Show High Resolution Flexible Fingerprint Sensor

FlexEnable and ISORG jointly launched a flexible fingerprint sensor with 500 dots per inch (dpi) image resolution. As the only flexible sensor technology that has achieved such high resolution, it is suitable for applications requiring standard-compliant fingerprint enrolment and/or identification. The optical sensor is ultra-thin, light and robust, and can be seamlessly integrated into products including fingerprint scanners, smartcards, mobile phones and wearables.
 
FlexEnable and ISORG have collaborated with Green Bit, a leading global provider of fingerprint scanners, to show that their flexible fingerprint sensor technology is ready for integration into products. The sensor has been paired with Green Bit’s image enhancement software to prove its ability to create FBI-certifiable images.
 
The high resolution of the flexible sensor has been enabled by FlexEnable’s organic thin-film transistors that offer better electrical performance than amorphous silicon and very low-leakage. ISORG not only supplies the photodiodes able to capture the fingerprint, but also has developed all the reading electronics and the related algorithms. The ISORG PLASMA development platform will accelerate sensor evaluation and product development for all customers.
 
Because it is made of organic electronics on a plastic sheet, the 500 dpi flexible fingerprint sensor is only 0.3 mm thick, bringing design and functional benefits to biometric applications. As well as detecting fingerprints, the sensor can capture veins, providing a second level of security since each user’s finger vein pattern is unique and requires the user to be alive for positive detection. Moreover, the technology enables large area sensors that can detect five fingers, allowing more information to be collected, bringing additional security benefits.
 
It can be curved and applied to almost any surface, unlike traditional fingerprint sensors that have form factor constraints due to the use of glass. The large area sensor can unlock new applications such as wrap-around fingerprint sensors for mobile phones or car steering wheels.
 
“The development of a 500 dpi plastic fingerprint sensor represents a major breakthrough in the commercialization of flexible fingerprint sensors, paving the way for FBI-certification of low cost and flexible fingerprint sensors over large areas,” Chuck Milligan, CEO of FlexEnable, said. “This will open the door to a wider range of applications including law enforcement, border control and high-security banking transactions.”
