A new optical sensor was successfully tested in the "magnetically best shielded room on Earth." The sensor does not need advanced cooling and is very small. Its suitability was proven for biomagnetic measurements in the picotesla range. So, magnetocardiographic measurement devices -- to be used as a supplement or an alternative to the ECG -- could become simpler and less expensive.
