本研究探讨一种可由蟑螂背负的酵素生物燃料电池。BFC通过海藻糖酶和葡萄糖脱氢酶（GDH）反应系统从昆虫血淋巴中的海藻糖产生电能，所述海藻糖酶和葡萄糖脱氢酶（GDH）反应系统将海藻糖水解获得的β-葡萄糖还原。首先，用3D打印机设计并制造了可昆虫安装的BFC（imBFC）。评价了阳极修饰的聚-L-赖氨酸、维生素1 β、心肌黄酶、烟酰胺腺嘌呤二核苷酸、GDH和聚（4-苯乙烯磺酸钠）在imBFC中的电化学反应，观察到氧化电流为1.18 mA cm（-2）（在+0.6 V vs. AglAgCl）。然后，评估imBFC的性能，并获得333 μ W（285 μ W cm（-2））的最大功率输出（在0.5V下）。此外，LED器件和无线温度和湿度传感器器件的驱动都由imBFC供电。这些结果表明，imBFC具有足够的潜力作为新型无处不在的机器人，如昆虫半机械人的电池。(C)2015 Elsevier B.

This study investigated an enzymatic biofuel cell (BFC) which can be backpacked by cockroaches. The BFC generates electric power from trehalose in insect hemolymph by the trehalase and glucose dehydrogenase (GDH) reaction systems which dehydrogenate (beta-glucose obtained by hydrolyzing trehalose. First, an insect -mountable BFC (imBFC) was designed and fabricated with a 3D printer. The electrochemical reaction of anode-modified poly-L-lysine, vitamin 1(3, diaphorase, nicotinamide adenine di nucleotide, GDH and poly(sodium 4-styrenesulfonate) in the imBFC was evaluated and an oxidation current of 1.18 mA cm(-2) (at +0.6 V vs. AglAgCl) was observed. Then, the performance of the imBFC was evaluated and a maximum power output of 333 mu W (285 mu W cm(-2)) (at 0.5 V) was obtained. Furthermore, driving of both an LED device and a wireless temperature and humidity sensor device were powered by the imBFC. These results indicate that the imBFC has sufficient potential as a battery for novel ubiquitous robots such as insect cyborgs. (C) 2015 Elsevier B.V. All rights reserved.
