Research group of the University of Illinois led by John Rogers believes that the muscle strength of the bodies can be used to produce electrical energy, which is necessary for the operation of pacemakers and some implants, reports New Scientist.
This assumption was made on the basis of the presence in the muscle tissue of the piezoelectric effect. The crystal lattice during deformation form of electrical impulses. Special nanobelts from high-tech material (lead zirconate-titanate + silicone) allow you to collect energy and to direct it in the right direction.
As a result, scientists have obtained a device which records the electrical impulses. Trial and error was installed the most active tissue. It was the muscle of the ventricles of the heart. 1 square centimeter produced 0.2 microwatt energy. Scientists report that this is enough to feed a standard pacemaker.
The discovery will help in the development of new medical devices that improve the quality of life of patients.
