Abstract
Of course, the space in the human body was limited, so, micro machining technology and the nano technology are the important tools for the development of the various kinds of internal artificial organs. Surface finishing technology with nano level DNA coating, various kinds of nano sensing devices including optical fiber sensor with nano size diaphragm and diamond like carbon nano film, nano actuator, and transcutaneous energy transmission system with nano particle magnetic shielding technology are the common useful technology for the development of various kinds of artificial implantable organs. By the use of these common technologies, circulatory assist systems including total artificial heart with undulation pump, ventricular assist device including rotary blood pump and artificial myocardium, artificial esophagus, drinking stent with peristaltic movements using SMA actuator with nano technology, artificial sphincter and epilepsy control machine are now under development. In this paper, various kinds of artificial internal organs by the use of nano technology are introduced and discussed.
