The biometrics arms race and the future of in-surface fingerprint sensors | BiometricUpdate

Ultrasonic fingerprint sensor technology based on Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) will make leaps and bounds in the coming years and could show up as early as later this year in devices like the Samsung Galaxy S10 and its rumored under-display ultrasonic fingerprint sensor.


Moving forward, ultrasonic fingerprint sensors will become the predominant biometric sensing modality in the multi-billion dollar fingerprint sensing market due to the technology's accuracy, ability to sense through solid objects like an edge-to-edge smartphone display, ability to sense wet fingers on wet surfaces, and "fool proof" ability to sense 3D transdermal fingerprint images.


For these reasons, ultrasonic fingerprint sensors will displace older fingerprint sensing technologies in applications like smartphones, laptops, wearables, automotive, and many other IoT devices.
