Effectively monitoring and diagnosing astronauts’ neuromuscular conditions during space missions is crucial for adapting their training. The MyoQuant project is dedicated to investigating the utility of magnetomyography with optically pumped magnetometers (OPMs) to surpass conventional methods in a non-invasive manner.
Leveraging warm alkali atom vapors, laser light, and external magnetic fields, OPMs offer a flexible and non-invasive solution. Our primary objective is to develop a compact Mx-type magnetometer utilizing cesium vapor, delivering high bandwidth and robustness suitable for moderately shielded environments in space.
We provide an overview of the current state of development for our compact OPM and discuss our progress in tailoring the sensor for biomedical applications. Facilitating additive manufacturing of ceramics and investigating wafer-based MEMS vapor cell fabrication techniques, we aim to develop a micro-integrated sensor package for extended space-borne missions.
