Japan Display Inc., through joint R&D with the Someya Group of the Department of Electric and Electronic Engineering, School of Engineering, University of Tokyo, developed a thin image sensor that allowed for both high-speed readout and high-resolution imaging.
Integrating low-temperature polysilicon thin-film transistors with high mobility and high-sensitivity organic photodetectors has enabled to create a single sensor that measures not only pulse wave distribution, which requires high-speed readout, but also biometric information, such as fingerprints and veins, which require high-resolution imaging.
At 15 micrometers thick, the sensor is lightweight and bendable. As for biometric authentication, it is expected that the sensor will be applied to high-security authentication systems to prevent imitations and impersonations by obtaining both biometric information (fingerprints and veins) and biometric signals (pulse waves).
The results of the research were published in the online version of the British science magazine Nature Electronics on Jan. 20, 2020.
The research received JST-Mirai Program Small Start Type (full-scale research ACCEL) (JPMJMI17FI) support from the Japan Science and Technology Agency (JST).
