Only the size of a sugar cube recently an atomic level sensor chip was successfully invented, it is reported that the sensor can measure brain activity effectively, according to the NIST researchers say is to further explore the field of human nerve milepost and disease. We reported the sensor in 2004, and in 2010 it was successfully implanted into the human heart. This week, researchers said the Optics Biomedical Express on the official release of the sensor on the journal.
In this small sensor is equipped with 100 billion rubidium atoms, and the fiber optical detection mark, which will help the neural exploration. NIST chairman Svenja Knappe said: "we are going to make smaller sensor so that they can be closer to the signal source, and a study on reducing the cost and price" that the sensor is expected to improve the detection of brain activity in the MEG project, and has begun to study this aspect. At present, the research team in Berlin, Germany, with the world's most advanced research equipment is expected to break the gap in the field.
