Cardiac-Energy Harvesting

Implantable devices, aiming to solve problems such as heart failure, obesity, blood pressure control, wound healing, neural-stimulation and drug delivery, have made significant progress in clinical applications in recent years.

Self-powered implantable devices with flexible energy harvesters are of significant interest due to their potential to solve the problem of limited battery life and surgical replacement. The flexible electronic devices made of piezoelectric materials that enable mechanical-to-electrical energy conversion from the natural contractile and relaxation motions of the heart have been employed to harvest energy .
