Title: Huawei’s New Ultrasonic Fingerprint Patent: A Possible Leap Towards Independent Biometric Technology
Huawei, the leading global tech company, has recently filed a patent (CN117058725A) for an innovative “ultrasonic fingerprint” sensor [1]. This patent application might suggest Huawei’s intention to develop its own ultrasonic fingerprint recognition technology, making a significant stride towards biometric independence from other companies [2].
Currently, many high-end smartphones utilize ultrasonic fingerprint sensors for enhanced security. Notably, Samsung’s Galaxy S10 series was the pioneer in introducing this technology to the flagship market [3]. However, the prevalence of these ultrasonic fingerprint solutions is restricted due to Qualcomm’s patent control. Huawei’s new patent could potentially provide an alternative, thereby reducing their dependence on third-party companies’ intellectual property.
The patent, titled “Ultrasonic fingerprint recognition module, system and electronic device,” provides a detailed description of the sensor’s design, featuring a stacked common electrode, a piezoelectric layer, and an array of pixel electrode units [4]. The technical specifications elucidate how the sensor operates in both transmitting and receiving modes to capture more precise fingerprint information.

Ultrasonic fingerprint sensors are increasingly popular in premium devices due to their ability to function effectively under various conditions, including wet fingers or extreme temperatures. However, the current market is dominated by solutions from a few key players like Qualcomm. Huawei’s patent application implies their determination to create an independent ultrasonic fingerprint recognition technology [6].
The intricacies of the patent application might be technically complex. Nevertheless, its significance lies in Huawei’s ambition to develop their own ultrasonic fingerprint technology and potentially reduce reliance on other companies’ solutions. This could result in more autonomy in innovation for the tech giant.
