Researchers from China and Germany create room-temperature magnetic sensor
Scientists from China and Germany have engineered a new magnetic sensor capable of detecting signals significantly weaker than the Earth's magnetic field without needing cooling, as it functions at room temperature. This technology could be utilized for tracking brain activity or hunting for dark matter particles. Typically, detecting such magnetic fields necessitates temperatures near absolute zero, which requires expensive liquid-helium cooling infrastructure.
