Researchers at the Department of Aerospace Engineering at the University of Michigan claim that they have designed a device that can collect energy from a human heartbeat and convert it into electrical energy for use in a heart rhythm regulator or implanted heart Rectifier defibrillator use. These small medical machines are responsible for sending electrical signals to the heart to help the heart maintain normal beats.
Dan Inman, head of aerospace engineering, pointed out: “The related medical costs are often very high. Patients who rely on heart rate regulators must be replaced every seven years. Assuming that the patient is only 2 years old, then, perhaps, they must carry out The second most open heart surgery. "
Inman said that they have developed a device that can harvest energy from the human body to supply the heart rhythm regulator. In the future, patients will not need to replace the battery every 7 to 10 years.
There is currently no prototype of the device, but the researchers claim that they have “conceived detailed plans for blueprints and performing simulations†and confirmed their feasibility. The design includes a one-hundredth inch thin piezoelectric ceramic material that can vibrate with the heartbeat and convert energy into electrical energy.
The researchers say they have designed the shape of the ceramic layer to collect vibrational energy in a wide frequency range. In addition, the design also incorporates magnets, which are mainly used to strengthen the electrical signal from vibration.
Energy harvesting equipment produces 10 times as much energy as the heart rhythm regulator requires, and the researchers claim that this confirms that the piezoelectric energy harvester can continuously power the heart rhythm regulator.
The energy harvester was originally designed for light unmanned aircraft to generate power from the vibration of the wing.
The preliminary results of this study have been published at the American Heart Association's 2012 scientific conference.
