Lawrence LeBlond for redOrbit.com - Your Universe Online The artificial pacemaker, a device that helps regulate the human heart through electrical impulses, has been widely used in cardiac patients for decades. However, these patients must undergo regular procedures to replace batteries when they wear out, raising the risk for infections and other complications. But now, researchers believe they have a new form of energy that can power pacemakers well beyond the life of conventional...

A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves. Engineering researchers at the University of Michigan designed a device that harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator. These mini-medical machines send electrical signals to the heart to keep it beating in a healthy rhythm. By taking the place of the batteries that power...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
