CW34_Sensor-Article-Series_Part 1.jpgWe try to explore, why Infineon leads the development of sensors in the IoT era. Part 3: Innovative Technology

The third type of innovation is in technology. Process is the core competitiveness of semiconductors. CMOS is the longest lasting, most commercialized and lowest cost technology in the semiconductor industry. Compared to the traditional GaAs or the popular SIGE process, Infineon’s latest CMOS mmWave radar sensor has lower costs, higher integration, lower power consumption and smaller size. It is incredibly suitable for consumer applications.

Thanks to its high accuracy, Infineon’s mmWave XENSIVTM 60GHz radar sensors, with an ultra-wideband of up to 7Ghz, enables short-range radar sensing including presence detection, image segmentation, gesture recognition, material sorting and tracking vital signs (breathing, heart rate and even blood pressure). Additionally, this 60GHz radar sensor has been demonstrated to be a powerful sensor for various industrial and consumer applications including the Google Pixel 4 smartphone and Samsung TVs.

The mmWave radar is especially suitable for the privacy-demanding family IoT environment because it cannot collect specific face information. For instance, “Better Safe”, a smart elder care solution by Infineon’s partner Tsingray, uses mmWave chips for non-contact accurate perception of vital signs (such as breathing and heart rate) and body movement recognition. This solution helps sleep improvement, provide early warning of potential diseases, and even monitor any falls an elderly person might have.

Another typical IoT application of mmWave radars is presence detection. For example, when one enters the house, the air conditioning, lighting or television will automatically turn on; when no one is present, these power-consuming devices will automatically switch to the standby mode. This sensing feature greatly improves the energy efficiency for IoT products, and significantly extends the standby time for battery-powered products.

The high-precision mmWave radar offers a host of advantages over the traditional passive infrared (PIR) technology in presence detection applications. These include greater accuracy and more precise measurement of static human body, especially when sitting still in front of the television. Additionally, the radar can penetrate non-metallic surfaces without opening holes, making it more convenient for product design.

To reduce the threshold of the mmWave radar, Infineon adopts the Antennas in Package (AIP), and supports an automatic operation mode that does not require any hardware or software modification. This enables engineers, who do not have expertise in RF, antenna or radar signal processing, to easily add the mmWave functionality to their products.
