“…The power has stable output performance, sustainable operation, and strong environmental adaptability [1][2][3][4][5][6]. The miniaturized RTG can be applied in long-term service meteorological/seismic monitoring stations that are widely distributed on the surface of the planet, small landing vehicles at extreme latitudes or areas with low solar flux, atmosphericsurface-flow monitoring systems, underground detectors [7], deep space micro spacecraft [8], wireless sensor networks [9], self-powered radiation sensors [10], deep-space robot probes [11], and radio observatories on the lunar surface [12].…”
