Researchers Build a Low-Power Radar on a CMOS ChIp
The international R&D hub Imec has made a millimetre-wave motion detection radar integrated in a standard 28nm CMOS chip, reports Electronics Weekly, adding that it consumes just 62 mW,"making the sensor integrable into small, battery-powered devices..."The radar operates in the frequency band around 60 GHz, a license-free ISM band that can be used for new IoT applications for industrial and medical purposes... "Being extremely compact and energy efficient, the 60 GHz radar system can be integrated in smart health devices such as smartphones, health monitoring systems or wearables", says Barend van Liempd, program manager radar at imec. "The radar enables such devices to sense their surroundings, which will shape the way in which we control and use these devices. For instance, a phone with integrated radar on your bedside table can monitor sleep quality by contactless tracking of breathing rate and heart rate variability. The radar is as well suited for classification of other physical activities, which will open a new range of smart applications in the context of personalized health, baby monitoring, sports, elderly care, patient monitoring, nurse efficiency or worker safety." "Our prototype shows that radar technology is becoming ready for the next big step: the use in battery-powered devices. Now, we are looking for companies that want to exploit these ideas to enter the market by realizing new radar solutions", says Kathleen Philips, Director IoT at imec. "It is thought to be useful for detecting finger and hand motion, heartbeat and a person's speed and position..." writes Joe2020, "but I'm sure Slashdot readers can think of a variety of other uses for it."Read more of this story at Slashdot.
