Effect of microwave on some electrical properties of wet bones

Abstract:<br /> In this research we have to study the effect of microwave radiation on some electrical properties of the wet bone, it is included to measure the electrical current and potential in bones before and after exposure to microwave radiation. The microwave uses a near-field focused energy (90-180 watts at 2.45 GHz frequency). Its found that the value of electrical current and potential produced in the bone exposed to microwave radiation are more than the value of electrical current and potential for unexposure bones, while the resistance is less under the same conditions. These differences in current and potential may be attributed for bioelectrical sources such as blood which contains electrically charged ions and the separation of ionic charges will produce an electromotive force, which is a voltage between points in fresh bone. <br /> The generated ionic current in blood which regarded carrier of the basic elements to buildup of bone will stimulate and increase the callus material around the fractures in bones and hence improves and speeds its healing.
