So the Ultrasonic sensor will be more accurate, less ugly and yes it will take the gesture control to the next level. Additionally, it also reduces the power consumption and the cost of manufacturing.

Another big differentiator is that ultrasonic sensors are much lower power than IR sensors. An example is when sensors are deployed to detect a human presence or occupancy sensing. Chirp’s ultrasonic ...

The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic ...

For example, the Chirp uses a tiny Piezoelectric Micromachined Ultrasonic Transducer (PMUT). The sensor’s membrane is driven to move up and down, pushing the air back and forth and creating ...

For a detection range of up to 2,000 mm, ultrasonic sensors can be as close as 8 m. Marcel Ulrich at Pepperl+Fuchs provided information for this column. About the Author ...

According to a patent application spotted by Engadget, Sony is planning on adding ultrasonic location analysis to the control, as well as Wiimote-style IR tracking.

Google’s upcoming Pixel 9 lineup will reportedly feature a faster, more reliable ultrasonic fingerprint scanner that should make it easier to unlock your phone. Optical sensors are out ...

The bottom line is an ultrasonic under-display fingerprint sensor is always better than an optical sensor. So, kudos to Google for finally making the switch. The Pixel Fold 2 won’t get this upgrade ...
