A group of scientists from the University of Buffalo is developing a pacemaker with no battery. Energy to his work will highlight the heart. As the basic technology became the piezoelectric system. It transforms vibration energy into electricity, says NDTV.
If the development is successful, the pacemakers will be safer and cheaper for patients. Also there will be no need to change batteries every 5-12 years. It is assumed that the device size will not exceed pocket watch.
The absence of wires and new technologies make life easier for patients. You have already created the first prototype able to ensure a normal heart rhythm. Now scientists are busy preparing for animal testing. Previously, they will take about two years. Further research group will move to the first tests on human volunteers with heart disease.
