Brain-Computer-Interface: Focus on diamond-based quantum sensors
|Much has been developed in the field of prostheses and exoskeletons in recent years. However, the possibilities for a truly intuitive and, above all, non-invasive control systems are still lacking. The sensors currently in use are not sensitive enough for this. A consortium from research and industry wants to change that with the NeuroQ project.|
|Last year, researchers at Fraunhofer IAF made a real breakthrough. For the first time, they were able to measure a magnetic field via stimulated emission. “So we have been able to show a magnetic field-dependent cavity signal, and for the first time.” The project leader, Jeske, is pleased to report. “Otherwise, we have only measured the magnetic field via fluorescence.” Compared to the fluorescence measurement, the laser signal was not only significantly stronger, but also much richer in contrast.
Now the consortium must transfer this laser system, including the measurement methodology, into a sensor system and then integrate it into an industrially usable module
