使用需要高功率的无线传感器来监测环境的挑战之一是找到一种可以产生足够电力的可再生能源。沉积物微生物燃料电池（SMFC）被认为是一种可替代的远程监测可再生能源，但目前的研究表明，SMFC只能产生几到几十mW的连续功率。这限制了SMFC作为兆瓦级功率的替代可再生远程电源的使用。如此低的功率仅足以操作低功率传感器。然而，有许多远程传感器需要更高的功率，在瓦特的数量级。由于功率管理技术的限制，使用SMFC来为需要瓦特级间歇功率的远程传感器供电的当前技术是有限的。我们的目标是开发一个电源管理系统（PMS），使SMFC操作一个远程传感器消耗2.5W的功率。我们设计了一种定制的PMS，将微生物能量存储在电容器中，并在短时间内使用存储的能量。我们的研究结果表明，SMFC可以是可行的替代可再生能源的远程传感器需要高功率。(C)2010 Elsevier B.V.保留所有权利。
One of the challenges in using wireless sensors that require high power to monitor the environment is finding a renewable power source that can produce enough power. Sediment microbial fuel cell (SMFCs) are considered an alternative renewable power source for remote monitoring, but current research on SMFCs has demonstrated that they can only produce several to tens of mW of continuous power. This limits the use of SMFCs as an alternative renewable remote power source to mW-level power. Such low power is only enough to operate a low-power sensors. However, there are many remote sensors that require higher power, on the order of watts. Current technology using a SMFC to power a remote sensor requiring watts-level intermittent power is limited because of limitations of power management technology. Our goal was develop a power management system (PMS) that enables a SMFC to operate a remote sensor consuming 2.5W of power. We designed a custom PMS to store microbial energy in capacitors and use the stored energy in short bursts. Our results demonstrate that SMFCs can be viable alternative renewable power source for remote sensors requiring high power. (C) 2010 Elsevier B.V. All rights reserved.
