Award for First Hi-Res Flexible Image Sensor Designed on Plastic

Isorg, pioneer in printed organic photodetectors and large-area image sensors, won the 2017 Best of Sensors Expo – Silver Applications Award for the first large-sized high-resolution flexible plastic fingerprint sensor, co-developed with FlexEnable.

The high-resolution, ultra-thin, 500 dpi flexible image sensor (sensitive from visible to near infrared) offers system integrators unique advantages in performance and compactness. Its ability to conform to three-dimensional shapes sets it apart from conventional image sensors. The device provides dual detection: fingerprinting as well as vein matching. Due to its large-area sensing and high-resolution image quality, the device is highly suited to biometric applications from fingerprint scanners and smartcards to mobile phones, where accuracy and robustness as well as cost-competiveness are key.

Several biometric solution providers have sampled the flexible image sensor, verifying its readiness for deployment in products and compliance with FBI Image Quality Standards (IQS).

“Isorg is very honored to have received an international award for our groundbreaking high-resolution flexible image sensor technology whilst attending the most important global trade event dedicated to sensor innovations,” said Emmanuel Guerineau, General Manager and CFO at Isorg. “We are delighted to have collaborated with FlexEnable to produce the world’s first printed electronics image sensor that overcomes the limitations of traditional sensors. Biometric solution providers will be able to take advantage of the key differentiating factors that our technology brings, such as customized formats in large and small sizes, and easy integration. We see these opening up new opportunities across multiple applications.”

Isorg is planning to launch high-volume production of the flexible image sensor at its new plant in Limoges, France, in order to support its large-scale commercialization in the global biometrics market. The global biometrics hardware market is expected to grow from $ 3.9 billion (approx. € 3.4 B) in 2016 to $ 6.2 billion (approx. € 5.4 B) by 2021, according to the Yole Développement report on ‘Sensors for Biometry and Recognition 2016’.

Central to the 500 dpi flexible image sensor is an organic photodiode (OPD), a printed structure developed by Isorg that converts light into current – responsible for capturing the fingerprint. Isorg also developed the readout electronics, the forensics quality processing software and the optics to enable seamless integration in products. FlexEnable, the leader in developing and industrializing flexible organic electronics, developed the Organic TFT backplane technology, an alternative to amorphous silicon. This partnership between the two companies began in Q4 2013.

“We are delighted that the large area flexible fingerprint sensor we developed with Isorg has been recognized with such a prestigious award. Thanks to being thin, light and glass-free, the sensor can be conformed to almost any surface to enable new form factors and use cases not possible with conventional fingerprint sensors,” said Paul Cain, strategy director at FlexEnable.

Designed on a large area (3″ × 3.2″; 7.62 × 8.13 cm) plastic substrate, the flexible image sensor is ultra-thin (300 microns), therefore remarkably lightweight, compact and highly resistant to shock.

Sensors Expo and Conference, held in San Jose, California, is the largest gathering of engineers and engineering professionals involved in sensors and sensing-related technologies. The Best of Sensors Expo Awards are designed to spotlight the advances in both innovations and real-world applications of sensors. (Source: ALA)
