No, the sensors measure a continuum of force or displacement along a line or rotational axis, 1D is correct.

That would be a different use of dimension.

The measurement of any one of those is a 0 dimensional tensor, a single number.

But then you are right, what. is being measured by that one sensor is 1 dimensional.

But all single sensors measure across a 1 dimensional variable. Whether it’s linear pressure, rotation, light intensity, audio volume at 1 frequency, etc.
