Researchers at the University of California, Davis and Berkeley have managed to miniaturize low-depth ultrasound technology to create a fingerprint sensor that can scan your finger in 3D. This low-power technology, which could improve on the robustness of current-generation capacitive scanners, could soon find its way to our smartphones and tablets.
