FlexEnable and ISORG's flexible fingerprint sensor offers an image resolution of 500 dots per inch (dpi). Only 0.3mm thick, the flexible optical sensor is suitable for applications requiring standard-compliant fingerprint enrolment and/or identification.

Its conformability makes it easy to integrate into products such as fingerprint scanners, smartcards, mobile phones and wearables.

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.

Made of organic electronics on a plastic foil, the large area sensor has been paired with Green Bit’s image enhancement software to prove its ability to create FBI-certifiable images. For additional security, the sensor can be made in large areas to detect five fingers; it can be curved and applied to almost any surface, for example wrapped around mobile phones or car steering wheels.

The high resolution of the flexible sensor has been enabled by FlexEnable’s organic thin-film transistors that boast better electrical performance than amorphous silicon and very low-leakage. ISORG supplied the photodiodes able to capture the finger print and developed all the reading electronics and the related algorithms.
