Patent for ultrasonic fingerprint biometrics among thousands Huawei files each year

A Huawei patent for ultrasonic fingerprint identification technology has been recently published. The patent application for CN117058725A describes “an ultrasonic fingerprint identification module, an ultrasonic fingerprint identification system and electronic equipment” that uses piezoelectric layers and stacked circuit substrates to “improve the accuracy of identifying fingerprint information.”

The move suggests Huawei may be moving to challenge Goodix, which many companies including Samsung currently rely on for ultrasonic fingerprint tech, but is restricted by Qualcomm patents, per a report in Gizmochina. …
