A cathode of smooth platinum in a right endoatrial position and an anode of Domal magnesium were used to construct a hybrid bioelectric battery designed to power a pacemaker. In use the cathode is gradually covered by a coating consisting of a crystalline layer and a layer of connective tissue. This coating is responsible for the system change in the reduction process at the cathode level: the transfer from an oxygen to a hydrogen system. This system change causes a voltage drop in the bioelectric battery. This paper deals with oxygen diffusion across the tissue layer, as well as with various spectral and chemical analyses. A high level of calcium and phosphorus in the different analyses carried out seems to show that the presence of these elements is related to the coating of the cathode. The effect on the formation of the coating of the position of the cathode is also discussed.
将光滑铂制成的阴极置于右心内膜位置，与多马尔镁制成的阳极一起构建了一种用于为起搏器供电的混合生物电池。在使用过程中，阴极逐渐被一层由结晶层和结缔组织层组成的涂层覆盖。该涂层导致阴极处还原过程中的系统变化：从氧系统转变为氢系统。这种系统变化导致生物电池中的电压下降。本文研究了氧在组织层中的扩散以及各种光谱和化学分析。在进行的不同分析中，高含量的钙和磷似乎表明这些元素的存在与阴极涂层有关。还讨论了阴极位置对涂层形成的影响。
