Google Pixel 10: Enhancing Biometric Security with Advanced Ultrasonic Sens

Published Date : 6/19/2025 

Google is set to unveil its most advanced ultrasonic fingerprint sensor in the upcoming Pixel 10 smartphones, marking a significant leap in biometric security and user experience. This upgrade, powered by Qualcomm and Precise Biometrics, promises faster, more reliable authentication for users. 

Google is pushing the boundaries of smartphone security with its latest upgrade to the ultrasonic fingerprint sensor for the Pixel 10 series. This innovation, set to debut in 2024, represents a major shift from traditional optical sensors, offering users a more seamless and secure way to unlock their devices. The move underscores Google's commitment to integrating cutting-edge technology into its flagship products, ensuring the Pixel 10 remains a leader in mobile biometrics. n n nThe Pixel 9, released in 2023, was the first Google smartphone to feature an ultrasonic fingerprint sensor, thanks to Qualcomm's advanced technology. This marked a departure from the optical sensors used in earlier models, which often struggled with accuracy in low-light conditions or when fingers were wet. The ultrasonic sensor, however, uses sound waves to create a 3D map of the fingerprint, making it more reliable and harder to spoof. Rival brands like Samsung also adopted similar technology, with Suprema's algorithms enhancing the performance of their Galaxy S24 models. Google's decision to upgrade this feature for the Pixel 10 highlights its focus on user feedback and technological advancement. n n nIn 2021, Qualcomm partnered with Precise Biometrics to integrate BioMatch Mobile software into its ultrasonic 3D sensors, adding an extra layer of security against spoofing attempts. This collaboration has since become a cornerstone of modern biometric systems, and Google is now building on that foundation. The new Pixel 10 sensor is expected to be even faster than its predecessor, with improved responsiveness for users with wet or unclean fingers. This advancement addresses a common pain point for smartphone users, ensuring a smoother experience in real-world conditions. n n nGoogle's 2024 product lineup will include four Pixel 10 models: the Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL, and Pixel 10 Pro Fold. The launch event, scheduled for August 20, will be followed by shipping on August 28, according to Android Headlines. The Pixel 10 will also be the first device to feature the Google Tensor G5 processor, a 3nm chip manufactured by TSMC. This powerful processor is expected to deliver significant performance gains, making the Pixel 10 a powerhouse for both everyday tasks and demanding applications. n n nThe shift from optical to ultrasonic sensors was driven by customer feedback. Previous models, which used Goodix's optical scanners, faced criticism for being slow and unreliable. Optical sensors rely on bright flashes of light to capture fingerprint data, which can be affected by moisture or dirt. By switching to Qualcomm's 3D Sonic Gen 2, Google aims to resolve these issues, offering a more robust solution. The 3D Sonic Gen 2 uses ultrasonic pulses to map the ridges and valleys of a fingerprint, creating a detailed 64mm² representation that is both accurate and secure. n n nBeyond the sensor upgrade, the Pixel 10 will introduce new features that enhance user convenience. One such addition is Qi2 wireless charging support, which aligns with industry standards for faster and more efficient charging. The device will also feature a third camera, upgrading from the Pixel 9's dual-camera setup. These improvements reflect Google's strategy to stay ahead of the competition by offering a comprehensive package of innovation and functionality. n n nThe success of the Pixel 10's ultrasonic sensor will likely influence the broader smartphone market. As biometric security becomes a key differentiator for consumers, manufacturers are under pressure to deliver reliable and advanced solutions. Google's partnership with Qualcomm and Precise Biometrics sets a new benchmark, proving that ultrasonic technology can outperform traditional methods in both speed and accuracy. This development is a testament to the company's ability to adapt to user needs and leverage partnerships to drive progress. n n nAs the Pixel 10 approaches its release, anticipation is building around its potential to redefine smartphone security. With its upgraded ultrasonic sensor, powerful Tensor G5 processor, and enhanced camera system, the device is poised to attract tech-savvy users seeking the best of the best. Google's continued investment in biometric innovation ensures that the Pixel 10 will not only meet but exceed expectations, solidifying its place as a leader in the smartphone industry.
