University of Utah physicists have developed an inexpensive, highly accurate magnetic field sensor for scientific and possibly consumer uses. The magnetic-sensing thin film, an organic semiconductor polymer named MEH-PPV, measures magnetic fields accurately with a drop of "plastic paint."
Although conventional magnetic resonance devices, like those in medical MRI machines, do very well, they are bulky and expensive, in comparison to the low cost and small size of the new magnetometers. The major use of the new devices is for intermediate strength magnetic fields, for which no existing device works as well, according to the researchers.
