Researchers from the AmericanDartmouth College, heart rate is powerful enough to recharge medical devices that save lives. The engineers of this college have developed a compact device that collects the kinetic energy of the heart and turns it into electricity. The latter can be fed by many types of implantable electronics.
Suitable compact batteries functionin defibrillators, pacemakers and other vital devices. Usually they have to be changed every 5-10 years, conducting an expensive and risky operation for the sake of this. So the problem of having a working source of energy that allows implantable devices to work all their life is incredibly relevant.
It is also important not to interfere with the functioning of the body.generally. The main requirements for the device are biocompatibility, flexibility, lightness and compactness, as well as compatibility with existing implantable devices and scalability to multi-functionality.
Available pacemakers suggest a change. Kinetic energy will be collected from the main electrode, which is attached to the heart, and then converted into electricity for batteries. The material collecting it and the electrode form a thin piezoelectric polymer film "PVDF". If you add on it a special porous structure, then it can work even with a small mechanical movement.
The device may be a sensor that monitorsreal time patient status. The development has already been tested on animals for 3 years. After some time, scientists are hoping to get permission to test it on people. They hope that their invention will be on the market within 5 years.
