Reproducible and reliable electrode manufacturing for water quality sensors is essential to ensuring accurate,low cost, consistent measurements. FREDsense Technologies Corp. has developed a novel, low cost system forthe detection of trace levels of contaminants in water samples using engineered bacteria. The bacteria produce aquantifiable electrical signal that indicates the amount of a compound present in the water sample. Theelectrical output from the bacteria is both fast and sensitive and is detected by the electrodes, making them anessential part of the biosensor system. Therefore, a method to fabricate them reliably, quickly and at a low costare essential for the successful implementation of the FREDsense system into current water monitoringworkflows. This study will determine the optimized electrodes parameters using a sputter deposition approachto their manufacture.

水质传感器的可重复和可靠的电极制造对于确保准确、低成本、一致的测量至关重要。FREDsense Technologies Corp.开发了一种新型的低成本系统，用于使用工程细菌检测水样中的痕量污染物。细菌产生一个可量化的电信号，指示水样中存在的化合物的量。细菌的电输出既快又灵敏，并被电极检测到，使它们成为生物传感器系统的重要组成部分。因此，一种可靠、快速、低成本地制造它们的方法对于将FREDsense系统成功实施到当前的水监测工作流程中至关重要。本研究将决定最佳的电极参数，使用溅镀沉积的方法来制造。
