A Heart-Powered Pacemaker

Pacemakers are a literal lifesaver for many people, and not just older folk. Anyone who needs their heartbeat to be artificially regulated can benefit from these devices. The pacemaker stimulates the heart into producing  a regular beat using a small electric current. Up till now, these devices needed battery power to operate, and of course the batteries would need to be changed periodically. However, there is now a prototype device that uses the piezoelectric effect, which allows it to also be physically smaller because no battery is needed.


The heartbeat keeps the pacemaker working properly while the pacemaker keeps the heart beating properly. This is important because this is one of the things that will make the prototype a real benefit.
