An Intracardiac Flow Based Electromagnetic Energy Harvesting Mechanism for Cardiac Pacing
Contemporary cardiac implantable electronic devices are powered by batteries. Replacement due to battery depletion may cause complications and is costly. To overcome these limitations, we present an energy harvesting device with a lever which is deflected by blood flow within the right heart. The kinetic energy of the lever is converted by an electromagnetic conversion principle. It generated a mean power of 14.39 / 82.64 µW at 60 / 200 bpm in an experimental setup mimicking flow conditions in the heart at 1 m/s peak flow. Therefore, it presents a viable alternative to batteries to power cardiac pacemakers.
