Today I was going through some papers and found a 2005 brochure for Biophan’s implantable biothermal source - a 3 mm-thick power source for implantable devices capable of generating electricity from body heat. This power source was being developed by Biophan in collaboration with the NASA Ames Research Center for Nanotechnology. The device is covered by U.S. Patent
Elema-Schoenander and the Very First Human Implants of a Pacemaker in Sweden (1958) and Uruguay (1960)
This is a picture of the first pacemaker to be implanted in a human patient. It was developed by Dr. Rune Elmqvist (1906–1996), a physician by training, but working for the Swedish company Elema-Schonander as an engineer. Dr. Elmqvist developed the device in cooperation of Åke Senning, senior physician and cardiac surgeon at the Karolinska University Hospital in Solna, Sweden.
