Is there any information 'bout Sensor Size?

[Ultrason]

Hello,

I've searched a lot, but couldn't find anything.
I wanna know whether there is an information about the Sensor Size of a camera in the Exif Metadata.

Because I can only see Focal Length....

Greets,

The EXIF FocalPlaneResolution tags should refer to the sensor for original images straight out of the camera.

And some maker notes contain addition sensor information.
