Traditional Radioisotope micro Battery (RMB) with direct conversion device of single layer array does not meet the requirements of micro sensor devices for its lower output power.

传统同位素微电池的能量转换结构采用单层阵列形式，造成电池输出功率较小，不能满足微型传感器件的需求。

This is a plutonium-driven device that produces power far more efficiently than the traditional Radioisotope Thermoelectric Generators (RTGs) used hitherto on space missions, such as on Cassini.
