Dielectric Elastomer Actuator to Assist Failing Hearts
The Integrated Actuators Laboratory, École Polytechnique fédérale de Lausanne (EPFL) in collaboration with the ARTORG Cardiovascular Engineering group has developed and tested a dielectric‐elastomer actuator (DEA) for the aorta that can assist patients with heart failure and offer a potential alternative to heart transplantation. In vitro experiments using a pulsatile flow‐loop showed the DEA reduced the energy that the heart has to exert by 5 percent and is driven by the physiological pressure of the aorta itself.
