Main Results:

  • Biologic fuel cells are not yet advanced enough for required power levels.
  • Electromagnetic systems necessitate bulky, frequently recharged batteries.
  • Radioisotope systems provide untethered operation but involve radiation exposure and containment risks.

Conclusions:

  • No single energy source is currently ideal for implantable artificial hearts.
  • Radioisotope systems offer unique advantages but require careful management of radiation hazards.
  • Further advancements in energy technology are crucial for the successful development of artificial hearts.
