研究了固态互补金属氧化物半导体（CMOS）兼容的葡萄糖燃料电池，单壁碳纳米管（SWCNT）薄膜和不同的碳纳米管含量（wt%）。SWCNT含量为3wt%的那些被发现开发出400 mV的最高开路电压（OCV），以及高电导率，0.53 μW/cm 2的功率密度和1.31 μA/cm 2的电流密度。通过将阳极浸入30 mM葡萄糖溶液中进行测量。OCV和功率密度随着燃料电池浓度的增加而增加。开发的燃料电池使用与人体生物相容的材料（单壁碳纳米管-葡萄糖）。结果，可以在单壁碳纳米管含量为3wt%的情况下获得400 mV的OCV，同时获得CMOS兼容的葡萄糖燃料电池的性能的改善，并且确定了影响燃料电池性能的参数。这种生物燃料电池是使用CMOS半导体工艺在硅晶片上制造的。这些发现对于实现可用于生物医学应用的移动的或可植入设备具有重要意义。
Solid-state complementary metal oxide semiconductor (CMOS)-compatible glucose fuel cells, with single-walled carbon nanotube (SWCNT) films and different amounts of carbon nanotube (wt%) were investigated. Those with a SWCNT content of 3 wt% were found to develop the highest open circuit voltage (OCV) of 400 mV, together with a high electrical conductivity, a power density of 0.53 μW/cm2 and current density of 1.31 μA/cm2. Measurements were performed by dipping the anode into a 30 mM glucose solution. The OCV and power density increased together with the fuel cell concentration. The developed fuel cell uses materials that are biocompatible with the human body (single-walled carbon nanotube-glucose). As a result, it was possible to attain an OCV of 400 mV with a single-walled carbon nanotube content of 3 wt% while improvements in the performance of the CMOS-compatible glucose fuel cell were obtained, and the parameters affecting the performance of the fuel cell were identified. This bio-fuel cell was fabricated using CMOS semiconductor processes on a silicon wafer. These findings are significant to realizing mobile or implantable devices that can be used for biomedical applications.
