This is a demonstration unit of a rechargeable pacemaker developed at the Johns Hopkins University under grants from several Federal agencies, including NASA. The unit includes micro-miniaturized electronics and rechargeable nickel-cadmium batteries among other technologies that were refined during the first decades of spaceflight. These technologies were essential for developing sophisticated scientific packages for space and NASA actively sought out companies that would apply the hardware and skills to Earth applications.
