Qualcomm's new ultrasonic fingerprint sensors can work underwater

Qualcomm has unveiled a next-gen fingerprint sensor at MWC Shanghai that uses ultrasonic technology that can be fitted under displays, glass and metal, and can scan through OLED displays up to 1200um. The sensors can detect heart beat and blood flow whether the screen is on or off, and can even be used underwater. The first phones to feature the technology will be launched by Vivo, a Chinese brand who apparently helped developed the technology with Qualcomm. Vivo phones are also available in India, Malaysia, Indonesia, Vietnam, Myanmar, and the Philippines.

For other Qualcomm partners, expect phones fitted with the new sensors to be available in the first half of 2018.

“We are excited to announce Qualcomm Fingerprint Sensors because they can be designed to support sleeker, cutting-edge form factors, unique mobile authentication experiences, and enhanced security authentication,” said Seshu Madhavapeddy, vice president, product management, Qualcomm Technologies, Inc. “This provides OEMs and operators with the ability to offer truly distinct, differentiated devices with added value on truly groundbreaking new devices.”
