Heartbeats

HeartbeatsA British team said: Pacemakers and defibrillators of the future may generate an extra power boost from a surprising energy source, Using a micro-generator powered by heartbeats, the British team on their experiment produced nearly 17% of the electricity needed to run an artificial pacemaker.

Paul Roberts (Southampton University Hospital in Britain) said: "This was a proof-of-concept study, and we provided the concept."

A pacemaker is a device of saving lives that sends electrical impulses to the heart to speed up or slow cardiac rhythm while an implantablecardioverter defibrillator signals the heart to normalize its rhythm if it gets too fast or slow.

• But now a days the devices are so small and the only way to produce more power is to run more functions is to increase battery size. The researchers said: increasing the size of this device would enable uncomfortable and cosmetically less appealing. The researchers continuously looking for increasing more power that helps the heart produce more than enough energy with each beat to pump blood as well as working with different materials in the micro generator, which they believe will produce significantly more power in their next-generation device

The device uses 2 bladders and a micro generator mounted on the lead of a pacemaker or defibrillator, the wire that connects the device to the heart.
