“…This phenomenon was found following a brief power law of w − α , where w was the stripe width and α was a number close to one [41]. Since the length of 30–50 μm is two orders of magnitude larger than the mean free paths of the ordinary bulk metals tested in these studies, the results raised arguments [44,45]. However, this study raised two interesting questions: What is the underlying mechanism?…”

In this paper, we report the results of slight changes in the thermopower of long W, Mo, Zn, Cu, brass, and Ti wires, that resulted from changes in the wire’s diameter or cross-sectional area. The samples used in the tests had a round shape with a diameter that ranged from tens of micron to 2 mm, which was much larger than the corresponding mean free paths of these materials. Nevertheless, a small change in thermopower, at the order of 1–10 nV/K, was repeatedly observed when the wire diameter was changed, or when the cross-sectional area of the wire was altered by mechanical methods, such as grinding or splitting. The results are consistent with previous observations showing that the thermopower in metallic thin film stripes changes with their width, from 100 μm to as little as 70 nm, implying a universal, geometric-boundary-related size effect of thermopower in metal materials, that occurs at the nanometer scale and continuously decreases all the way to the millimeter scale. This effect could be applied in the manufacturing of high-temperature sensors with simple structures.

“…This size effect of the Seebeck coefficient on the width of the thin-film stripe has been extensively studied [ 27 , 28 , 29 , 79 , 80 , 81 , 82 , 83 ]. It demonstrated that decreasing the stripe width from the micron to the submicron and nanometer scales reduced the sensitivity of TFTCs even further.…”

Temperature is a significant factor in determining and characterizing cellular metabolism and other biochemical activities. In this study, we provide a brief overview of two important technologies used to monitor the local temperatures of individual living cells: fluorescence nano-thermometry and an array of micro-/nano-sized thin-film thermocouples. We explain some key technical issues that must be addressed and optimised for further practical applications, such as in cell biology, drug selection, and novel antitumor therapy. We also offer a method for combining them into a hybrid measuring system.
