Currently, scientists hope that the future of artificial organs implanted in the human body does not use batteries,and organized psychology lectures, but to use as a fuel source to generate the body's own energy. Scientists demonstrate fuel cells implanted in mice, mice can be used to produce sugar in the current material success, the current can continue to use the battery a few months.
far the most powerful sugar fuel cell is called \exist in the experimental mice), which is known as \Scientists are developing similar devices in an environmentally diverse ways to generate electricity.
But in the past that glucose fuel cell is not suitable for human transplantation, which is due to the high acid battery status is not required to work the body is to be inhibited by a variety of ions. Newly developed battery systems from the above conditions, became the first effective implantable glucose biosensor cells, the mice in the experimental prototype for sustainable electricity supply at least 3 months.
Joseph Grenoble,[link widoczny dla zalogowanych], France - Fourier University biomedical engineer Phillip - San Gang (Philippe Cinquin) said: \Compensation on a number of body functions. \In this regard, and e-chemist just color Sang Ji - Si Niya (Serge Cosnier) in the combination of the two substances, before you put them in the physical assembly of the electrode area,[link widoczny dla zalogowanych], and then dialysis bag with a thin film package. The semi-permeable membrane to produce electricity while maintaining the enzyme and redox mediator agent to prevent leakage. This solution allows scientists the opportunity to investigate the most adaptable of the human body's enzyme material, before researchers often neglect this.
implanted battery power supply that depends on the load of glucose oxidase and polyphenol oxidase of the mixed graphite plate, which occupy the two poles of a total of 5 ml of 0.266 ml in the fuel cell, generating a maximum current of 6.5 micro-watts . On the specific method of fuel cells, published in \
researchers stressed that, 1 ml volume of the electrode is equivalent to 24.4 micro-watts to produce the current, more than 10 microwatts Current from shoulder much higher. Meanwhile, the new battery system advantages in size, usually 10-25 ml volume pacemaker.
body in mice based on the success of the test, the current surgical procedures have been adopted this design prototype human implants, Sang just said, has not yet been found that the battery is not suitable for any reason, the human body . He hopes to promote the use of the next 5-10 years.
Sang Gang said that the first fuel cell implanted artificial urinary sphincter applied to the artificial organs required current of 200 micro watts. Each year,[link widoczny dla zalogowanych], about 100 million current patients suffered urinary incontinence after prostate removal pain, their only solution is to pump implantation in patients with a heavy scrotum, the patient pressure generated when the urine. More in-depth future research goals can be used in artificial kidney fuel cells, artificial organs need the current 20 microwatts, one of the goals of artificial heart is to study, but the current organ requires at least a few watts.
not involved in the study of Chemistry, University of New Mexico physicists and chemical engineers Pula Man - Atta that Sower (Plamen Atanassov) said: \fuel cells show a higher level. \The problem is that the device produced by the extracellular liquid oxygen produced by low glucose levels 1,000 times higher than normal, I do not think it can completely supply of oxygen.
repair enzymes and redox through mediation agent, Sang just for this device were very much self-confidence, in an unpublished research study, and research colleagues recently Sang effectively improve the enzyme and redox mediator agent performance of 50%, and they stressed that the battery charge by the glucose bio-fuel is the future of artificial heart is still long-term research goals.
recently, scientists will study in the latest micro-battery implanted in experimental mice, using the mouse's own body can produce the current sugar substances, the micro-power battery lasts a few months.
\The technical obstacles is how to continue after the implantation of artificial organ supply. Scientists do not use artificial organs with external systems will be connected to the continuous power supply, or remove them from the body for battery replacement, they plan to use the body's own tissues to artificial organs to provide continuous current.
