The European Space Agency (ESA) has announced that a project it has backed has yielded a combined temperature and magnetism sensor. “Any time we can do more with less is a good result for the space sector,” notes ESA materials specialist Ugo Lafont. “Thanks to the unique properties of graphene, our prototype bi-functional sensor can measure magnetic field strength at the same time as taking temperature readings.
“And our tests show the sensor operates reliably from room temperature down to 12 degrees Kelvin. Normally separate temperature sensors are required to accurately measure such wide temperature ranges, right down to cryogenic levels.”
