IWR6843ISK-ODS: Any solution to locate where a person is and still get breathing and heart rate in vital_signs lab?

Big Fields

Part Number: IWR6843ISK-ODS

Hi,

I am running 68xx_vital_signs demo in mmwave_industrial_toolbox_4_4_1.

In this lab, the radar measures breathing and heart rate of a person sitting in front of the radar. This person has to be sitting still and facing the radar at about 1m~2m away from the radar.

I want to get breathing and heart rate of a person anywhere in a room.

I also want to get breathing and heart rate of a person who is standing or lying.

Do you have any solution or advice how to achieve my requirements?

If not, in what point is it difficult to achieve it?

Best regard,

Fields

    Hi Fields,

    The key idea/principle used in our Vital signs demo is to be able to accurately extract and phase information for very small displacements. In our demo, this requires the target to be sitting so that we can first lock-in on the range bin (distance of person's chest from the sensor) and then collect and measure the phase variations arising from breathing (somewhat macro) as well as heart beat which are more minute in nature, in that range bin.

    The theory behind the Vital signs demo is explained in the provided user guide so please look at that to get more idea.

    We do not have a demo to measure vital signs at a larger distance or anywhere in the room but it may be possible to implement those as long as you are able to filter out the phase variation pattern (of heart beat and breathing) reliably for the detected target(s).

     Regards

    Hi Fields,

    Please see the following video from a company named AVDS (http://www.avds.com.tw/). They have implemented this using TI mmWave device.
