Composite image showing a miniaturization progression relating the macroscale experimental platform to the final, nanoscale thermal image. From the bottom, a thumb and forefinger holding a printed circuit board next to a traditional glass bulb thermometer; the silicon chip on the circuit board; the silicon nitride membrane window in the silicon chip; and a temperature map of a heated aluminum wire on the membrane window. 

The sizes scales of the images are roughly 2 cm, 2 mm, 30 um, and 1.5 um, respectively.
