If you have an iPhone, you've got a notch. Now there's tech that can get rid of that notch ... and the same tech can bring secure Face ID to Android: at a fraction of the cost.In this TechFirst, I chat with Metalenz CEO Rob Devlin about his meta surfaces product. Not only can they produce about 10,000 lenses on a single 30-centimeter wafer, just like computer chips, they can now decode polarization information on surfaces from the light reflecting off of that.That gives them data on what that surface is made from, and that is a huge advancement for biometrics, phones, medical devices, and robots.The technology, which can capture and process unique wavelengths and polarization information, enables the creation of smaller, cheaper, and more efficient optical systems. Metalenz's partnership with ST Microelectronics has led to the integration of metasurface optics in products that have been previously sold in over 150 different smartphone models.
