The chip at the centre of the module is a 28nm CMOS chip that performs motion detection radar with 2cm resolution making suitable for vital sign monitoring and gesture recognition. As the radar chip consumes just 62mW it is possible to integrate it into portable battery-powered equipment.
The radar is suitable for frequency modulation and its high speed of modulation – 12 percent increase in frequency in 51.2ms provides a modulation bandwidth of 7.2GHz.
Experiments have demonstrated the sensor’s ability for multi-target detection, heartbeat detection at 5 meter and accurate tracking of a pedestrian’s position and velocity.
"Being extremely compact and energy efficient, the 60GHz radar system can be integrated in smart health devices such as smartphones, health monitoring systems or wearables," said Barend van Liempd, radar program manager at IMEC, in a statement.
Kathleen Philips, director IoT at IMEC, said: "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."
