NXP’s Trimension UWB radar portfolio enables fine motion detection

1 min read

NXP has unveiled the industry’s first single-chip solution to combine ultra-wideband (UWB) radar and fine ranging capabilities to enable high motion sensitivity for presence detection, vital signs monitoring and gesture recognition.

The expansion to the company’s Trimension portfolio and the integration of UWB radar enables devices to sense their environment, as well as range to other UWB-enabled devices. This makes it easier and more cost-effective to bring motion sensitivity, including presence detection, vital signs monitoring and gesture recognition, to mobile, Internet of Things (IoT) and automotive applications.

Ultra-fine motion detection, enabled by UWB radar, can help improve levels of safety, as well as convenience, in both the smart home and automotive markets.

For example, a smart baby monitor with UWB radar could detect a sleeping baby’s breathing and send parents an alert if patterns change. In the automotive market, the technology can be used to help protect against hot car tragedies, when a child is left unattended in a vehicle.

“Ultra-fine motion detection enabled by UWB radar offers new levels of safety and convenience for use cases as serious as alerting drivers to a baby in the backseat to one as simple as changing the TV channel with a gesture,” said Rafael Sotomayor, Executive Vice President and General Manager, Connectivity and Security, NXP Semiconductors. “The expansion of our Trimension portfolio includes single-chip solutions that combine the capabilities of UWB radar and ranging, to make it easier for developers in IoT, mobile and automotive markets to quickly integrate highly accurate, highly precise motion detection.”

The expanded portfolio includes the Trimension SR160 for IoT applications and forthcoming Trimension devices for mobile and automotive applications.

The Trimension SR160 is able to manage both radar and ranging functionality, using the same hardware for both modes to sense both the environment and other UWB-enabled devices

Operating at 6-8 GHz the device allows sensing to be reliable at sufficient distances for robust motion detection through a room or car interior; it also provides angle-of-arrival (AoA) information for ranging use cases for more precise localisation capabilities.
