? To get enough energy, we need high-density methods ,? explains engineer Jae Kwon, co-author of the study. ? Using batteries with radioisotopes we can provide six times more energy than with traditional chemical cells.? For this reason, he and his team have developed a nuclear battery the size of a coin that could be used as a power source for microelectronic and even nanoelectronic systems. ? When people hear the word ‘nuclear’ they think of something very dangerous ,? he admits. “However, nuclear power sources already safely power some devices such as space satellites and pacemakers, ” adds the researcher.
Kwon, who has already published his advances in the Journal of Applied Physics Letters , says that nuclear batteries could become thinner than a human hair.
