In this work, we propose an integrated self-powered sensing system, driven by a hybrid biofuel cell (HBFC) with carbon paper discs coated with multiwalled carbon nanotubes. The sensing system has a biocathode made from laccase or bilirubin oxidase, and the anode is made from a zinc plate. The system includes a dedicated custom-built electronic control unit for the detection of oxygen and catechol analytes, which are central to medical and environmental applications. Both the HBFC and sensors, operate in a mediatorless direct electron transfer mode. The measured characteristics of the HBFC with externally applied resistance included the power-time dependencies under flow cell conditions, the sensors performance (evaluated by cyclic voltammetry), and chronoamperometry. The HBFC is integrated with analytical devices and operating in a pulse mode form long-run monitoring experiments. The HBFC generated sufficient power for wireless data transmission to a local computer.

在这项工作中，我们提出了一个集成的自供电传感系统，该系统由混合生物燃料电池（HBFC）驱动，该燃料电池具有涂有多壁碳纳米管的碳纸盘。传感系统具有由漆酶或胆红素氧化酶制成的生物阴极，阳极由锌板制成。该系统包括专用的定制电子控制单元，用于检测氧气和邻苯二酚分析物，这对于医疗和环境应用至关重要。HBFC和传感器均以无介体的直接电子传输模式运行。在外部施加电阻的情况下，HBFC的测量特性包括流通池条件下的电源时间依赖性，传感器性能（通过循环伏安法评估）和计时电流法。HBFC与分析设备集成在一起，并通过长期监控实验以脉冲模式运行。HBFC产生了足够的功率，可以将无线数据传输到本地计算机。
