植入式生物燃料电池的体外实验

Experiments in Vitro of Biofuel Cell for Implantable Medical Devices

开发了一种利用生理体液的植入式生物燃料电池(BFC)原型装置.通过模拟人体生理环境,进行了植入式生物燃料电池的体外试验.讨论了葡萄糖反应液的浓度、温度和pH值对生物燃料电池输出电流的影响,实验结果表明:随着葡萄糖反应液浓度的降低,生物燃料电池的输出电流相应减少,持续供电时间缩短;随着反应液pH值的降低,生物燃料电池的输出电流增大;升高反应液温度会使生物燃料电池的输出电流产生振荡.

A prototype device of an implantable biofuel cell （BFC） that utilizes body fluid was developed, and experiments in vitro were carried out for the implantable BFC in a simulated physiological environment of human body, to investigate the influences of the concentration, temperature, and pH value of glucose solution on the electric current output of the BFC prototype device. The experimental results show that as the concentration of glucose solution decreased, the electric current output of the BFC decreased, and the sustaining time of power supply of the BFC shortened. On the other hand, the electric current increased with the decrease of the pH value of the glucose solution. Lifting the temperature of the reaction solution would cause oscillation to occur to the current output of the BFC.
