Huawei recently unveiled a patent for a new “ultrasonic fingerprint” sensor, potentially signaling a move towards developing their own ultrasonic fingerprint technology. This comes as many phone makers currently rely on solutions from Goodix, which are restricted by Qualcomm patents.
Samsung’s Galaxy S10 was the first flagship smartphone to feature the sensor
The patent, titled “Ultrasonic fingerprint recognition module, system and electronic device” (CN117058725A), details a sensor design that promises improved fingerprint identification accuracy.
Currently, ultrasonic fingerprint sensors are used in some high-end phones, especially Samsung‘s flagship S-series smartphones. However, these solutions are limited by patents held by Qualcomm. Huawei‘s new patent suggests they’re aiming to create an alternative ultrasonic fingerprint recognition technology, potentially freeing them from reliance on other companies’ patents.
The specifics of the patent delve into the technical details of the sensor’s construction, including a stacked common electrode, a piezoelectric layer, and an array of pixel electrode units. The technical breakdown describes how the sensor operates in both transmitting and receiving modes to capture fingerprint information with greater accuracy.
While the technical details might be complex, the key takeaway is that Huawei’s new patent hints at their ambition to develop their own ultrasonic fingerprint technology, potentially reducing their dependence on other companies’ solutions in the future.
