For almost 80 years, it has been known that electrons tend to heat up when they travel around bends because their flow lines get squished locally. No attempt has been made to measure the heat for which flow line imaging is first needed.
At the University of California, Riverside, a research team led by physics and astronomy professor Nathaniel M. Gabor in imaging streamlines of electric current by designing an electrofoil. This new type of device allows the contortion, compression, and expansion of streamlines of electric currents in the same way that airflow is contorted, compressed, and expanded by airplane wings.
