Magnetocardiography (MCG) techniques are based on improving the superconducting quantum interference device (SQUID) technology to enable the measurement of weak magnetic ﬁelds generated by the electrical activity of a human heart.
SQUID-based MCG systems require cooling, making them impractical and expensive.
At the Electron Science Research Institute, our researchers are collaborating with researchers at KRISS-Korea on the development of atomic magnetometers using optically pumped Alkali metal vapour for measuring the magnetic resonance in an atomic system by detecting the transmission intensity of circularly polarised light through Alkali metal vapour cells, thus enabling foetal sound monitoring at room temperature.
