Magnetic fields are ubiquitous ... This is particularly true for atomic sensors. Current technologies, like optically pumped magnetometers (OPMs), are capable of measuring field strength.
Recently, fires and other accidents caused by the use of non-original equipment manufacturer lithium-ion batteries (i.e., compatible batteries) have become a problem. However, these compatible ...
Researchers of University of Tsukuba have created a magnetic sensor system that verifies lithium-ion batteries (LIBs) by detecting differences in their internal structures and current flow patterns.
