Vein Detection with Near-infrared Organic Photodetectors for Biometric Authentication (Sensors Europe 2020)

Dr Daniel Tordera, Senior Scientist
Holst Centre

Presentation Summary

We combine a near-infrared (NIR) sensitive organic photodetector with a high-resolution 508 ppi oxide TFT backplane to create a large-area thin NIR detector. Using a NIR light source the detector is capable of imaging the (pattern of) veins under the skin in reflection, leading to improved biometric authentication.

Speaker Biography (Daniel Tordera)

Daniel Tordera is a Senior Researcher at Holst Centre working on image sensors and leading the development on near infrared photodetector solutions. He received his PhD in Nanotechnology at the University of Valencia in 2014, where he studied organic electronic systems based on ionic materials for light emission. He was CEO of Lec-Val Lighting, a spin-off created to commercialize the results obtained during his PhD. Subsequently, he spent 2 years as a postdoctoral researcher at Linköping's University in the field of optics and plasmonics for energy and sensing applications. He is an award-winning author.

Company Profile (Holst Centre / TNO)

Are you looking for a reliable development partner, who can help to accelerate your R&D projects in wireless autonomous sensors and flexible electronics ?
As a flexible, independent R&D centre, we can do just that: by testing alternative solutions and materials, by developing and validating new processes, by de-risking potential scale-up scenarios.
We help to close the gap between research and actual business, both in an open innovation setting and in dedicated 1-on-1 research trajectories.
By partnering with Holst Centre, you benefit from the know-how and expertise of our researchers and you gain access to our state-of-the art lab infrastructure. Moreover, we introduce you to an eco-system that covers the entire value chain, including material suppliers, equipment builders all the way to manufacturers of end-products. This allows you to accelerate your time-to-market considerably. By the end of the project, you not only acquire new product concepts, but also the materials, tools and contract manufacturers, ready to produce.
