While some devices have shown improved performance by combining layers with different thermopower signs in thermopile devices, this approach generally requires the use of different materials and altering the manufacturing process.

From Science Daily • Jan. 23, 2024

What the real limit of the spectrum is, is at present unknown; Mr. Langley with his bolometer, and rock-salt prisms, an instrument more sensitive than the thermopile, must have nearly reached it.

From Colour Measurement and Mixture by Abney, W. de W.

This may be proved experimentally with proper apparatus, as for example with an instrument known as the thermopile.

From Aether and Gravitation by Hooper, William George

We call those junctions in a thermopile 'couples,' and by getting the recording instruments sensitive enough, we can measure one one-thousandth of a degree.

From The Dream Doctor by Reeve, Arthur B. (Arthur Benjamin)

The measurements were chiefly of a qualitative character, and were made by interposing between the source and a thermopile a layer or plate of the substance to be examined.
