In this episode of ID Talk, we sit down with Rob Devlin, co-founder and CEO of Metalenz, to explore how metasurface optics are reshaping the future of facial recognition and mobile sensing. Rob walks us through the groundbreaking technology behind metasurfaces—flat, nanostructured lenses that replace traditional optical stacks—and how Metalenz’s latest product, PolarID, leverages polarization imaging to deliver secure, spoof-resistant face authentication in mobile form factors. We discuss the origins of the technology, its real-world deployment through a major partnership with STMicroelectronics, and its exciting potential for applications beyond biometrics—including healthcare, environmental sensing, and more.
