Feeding the pacemakers with the vibrations produced by the heartbeat

Feeding the pacemakers with the vibrations produced by the heartbeat

Despite the fact that pacemakers only require small amounts of power (around 1 millionth of a watt), their batteries have to be replaced periodically and that involves multiple surgeries for patients. Researchers have looked for ways to extend battery life - trying to generate energy with blood sugar, or the movement of the hands and legs - but these methods either interfere with metabolism or require more radical surgery. like passing a cable from the extremities to the chest area.

Aerospace engineers M. Amin Karami and Daniel J. Inman of the University of Michigan in Ann Arbor have developed a prototype device that could power a pacemaker using a source that is very close to the problem: cavity vibrations. thoracic that occur mainly due to the beating of the heart.

The authors describe the technique and its progress in a recent article in the AIP journal Applied Physics Letters (entitled "Powering pacemakers from heartbeat vibrations using linear and nonlinear energy harvesters").
