Paper detailing this breakthrough to be published by the Institute of Electrical and Electronics Engineers (IEEE) as part of a project under the National Key R&D Program of China in collaboration with Shanghai Jiao Tong University (SJTU).

MANCHESTER, England, Dec. 10, 2025 /PRNewswire/ -- Smartkem, Inc. (NASDAQ:SMTK), a company developing a new class of organic semiconductor technology, today 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.

A paper describing this new technology, titled 'Flexible 256x256 All-Organic-Transistor Active-Matrix Optical Imager with Integrated Gate Driver' and co-authored by Smartkem Chief Technology Officer, Dr. Simon Ogier, will be published by the IEEE and presented by Prof. Xiuyan Li, SJTU at the 71^st Annual IEEE International Electron Devices Meeting today, Wednesday, December 10^th, 2025, at 3:15pm PST / 6:15pm EST.

"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."

The paper will be published online following the IEDM 2025 conference in San Francisco. Available to view here.
