IWR1642BOOST: Seeing through materials

Lindsey Reynolds

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, , IWR1443BOOST

Hello,

Can the IWR1642 sensor see through materials such as rubber or plastic? I'm interested in an application which involves seeing through the sole of a shoe.

Additionally, does the IWR1642BOOST include the sensor as well or does the IWR1642BOOST and IWR1642 need to both be purchased?

Thank you,

Roman

Hello Lindsey,

Your ticket has been assigned to the appropriate engineer. They should respond as soon as they are available.

Hi Lindsey,

mmWave can penetrate certain materials such as plastic, drywall, glass and clothing etc. as mentioned in the overview page here:

http://www.ti.com/sensing-products/mmwave/what-is-mmwave.html

We have an experiment which shows mmWave's ability to detect objects behind a sheet of drywall.

While we haven't specifically tested with rubber or shoe soles, I believe it may be able to penetrate rubber depending upon the type and thickness. I would recommend experimenting with an IWR14xx/IWR16xx EVM (IWR1443BOOST or IWR1642BOOST) using the out of box demo Visualizer.

Would a 24GHz sensor perhaps be more appropriate for the application of detecting obstacles through shoes? If so, are there comparable units available at this frequency?

Hi Lindsey,

Given the lower frequency, 24 GHz may be able to penetrate deeper (than 77 GHz) into materials but I believe it would be better to experiment with 77 GHz as well in case it meets your use case requirements. Currently, TI mmWave Sensors support only the 76-81 GHz band.

Hi Lindsey,

Do you have any more questions in this regard? If not, can we close this thread?
