I came here to read how this works:

“The quarter-sized pacemaker from 2021 was powered with the help of a built-in antenna that limited attempts at further miniaturization. In contrast, the new device has electrodes that when exposed to body fluids generate an electrical current. This design eliminates the need for an external power source, wires leading out of the body, and an antenna.”
