Space Tags: Ultra-Low-Power Operation and Radiation Hardness for Passive Wireless Sensor Tags

Space agencies worldwide have a long-term vision of sending human missions to Mars [1]. The next favorable launch window occurs in 2033, and plans are ongoing to realize such endeavors. An essential part of this preparation is the search for new technologies to mitigate mission performance risks. A critical further technological advancement is passive or batteryless wireless sensor technology [2], [3], as used in the Internet of Things (IoT) [4], which can be favorably used to continuously monitor the physiological conditions of crew members in the space habitat and structural health of spaceflight equipment.
