Infineon has developed a 60 GHz radar chip for gesture recognition. It is used in Google’s Pixel 4 phone.

With an integrated antenna system, it senses the presence and movement of people and objects  or measures distances and speeds.

“With our radar technology, devices become ‘context-aware,” says Infineon’s Andreas Urschitz.

Infineon’s radar technology has its roots in the automotive sector. Radar sensors have been measuring distances, speeds and movements while driving for decades.

Infineon has developed these functions for small devices. The 60 GHz chip is a complete radar system with antennas on a very small area (5 x 6.5 mm) coupled with low power consumption.

It can perceive movements in rooms or measure distances from objects in the millimetre range.

With the appropriate software, the motion data is converted into functions, so that control via gestures is possible without touching the device.
