Vital Signal measurement using mm-wave

Lakshminarayana

Other Parts Discussed in Thread: AWR1642, AWR1843

Hi,

I've seen an example of contactless Vital signal measurement of driver I couldn't get more info on this like Design details/guidelines Could you please attach a link to that.

I'm interested in measuring Temperature, BP, heart rate.

Is it possible to measure the Temperature using mm-wave?

Could you please attach some guidelines?

Thanks.

Hi.

Please see the demo we have available in the Automotive Toolbox.

We can't measure temperature with mmwave sensor

thank you

Thanks.

So basically with AWR1642BOOST-ODS EVM We can test, right?

May I know why 4 Rx and 2 Tx antenna? Also, max Range can be achieved?

Is it possible to measure the Vital signal when the person is moving or they've to be in a resting position?

Yes, it is possible to use the AWR1642 ODS board.

This demo uses only one Tx antenna and one Rx antennna.

The 4Rx/2Tx antenna is a common antenna configuration that is useful in many other applications.

The vital signs demo works at a range ~1-2m without lens. For further range a lens can be added.

The person would have to stay still as shown in the video

thank you

Thank you.

Could you please attach a few guidelines on mm-Wave Antenna design? (it looks like a PCB Antenna ).

Is it possible to achieve more range with AWR1843?

How about IWR6483 on this application?
