Form-fitting, nanoscale sensors now make sense
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices to report on what they perceive.
Electronically active 2D materials have been the subject of much research since the introduction of graphene in 2004. Even though they are often touted for their strength, they’re difficult to move to where they’re needed without destroying them.
The Ajayan and Lou groups, along with the lab of Rice engineer Jacob Robinson, have a new way to keep the materials and their associated circuitry, including electrodes, intact as they’re moved to curved or other smooth surfaces.
The results of their work appear in the American Chemical Society journal ACS Nano.

Any thing that always returns the reading different from what would be read in its absense satisfies that requirement, simply by taking that returned reading to mean "the thing is being sensed", tautologically. It doesn't even need to be a sensor, /senso stricto/. A battery is a battery sensor - if you read 1.4V, you've almost certainly detected a battery.
Scientists really should get scientifically literate people to proofread their press releases.

"Ah yes, if we remove all useful information, then the idea of a sensor is a tautology".
Yeah, they're making useful things like photodetectors(i.e. camera without a lens). This is not buried deep in the article. You were one click away from it.

What is this "article" of which you speak?

To be fair, there were like 30 links in the summary no one would want to click on, and one that was useful.

There is a tautology here, but not how you've described it.
"What if a sensor sensing a thing could be part of the thing itself?"
Assume a sensor that always returns a positive result. Since the sensor is a part of the thing, the existence of the sensor is tied to the existence of the thing.
If the thing exists, the sensor exists and returns a positive result, thus "sensing" the thing. If the thing doesn't exist, then the sensor doesn't exist and does not return a positive result, thus correctly "sensing" that the thing doesn't exist.
Thus, such a sensor would be patently useless.
