Smartkem, Inc., a company developing a new class of organic semiconductor technology, announced that it has created the world's first all-organic-transistor (AOT) biometric sensor, in collaboration with the SJTU.
This novel technology significantly increases the sensitivity of optical detection for flexible biometric applications, such as finger or palm print recognition on curved surfaces and has the potential to help address challenges like fingerprint spoofing. By enabling advanced liveness detection techniques, the sensor can capture subtle signals that distinguish real fingerprints from fake ones, whether through multi-wavelength imaging or dynamic imaging that reveal motion or blood flow.
"This is a true world-first and a powerful demonstration of the many potential use cases for Smartkem's organic transistor platform," said Ian Jenks, Chairman and CEO of Smartkem. "By creating the first fully all-organic-transistor active-matrix biometric sensor, we've shown that OTFT technology can outperform conventional inorganic sensors in sensitivity, while enabling entirely new classes of flexible, curved biometric devices. This work opens the door to a new generation of lightweight, high-performance bio- and optical sensing."
