The PI's request funding to develop a low power, autonomous solid state sensor for simultaneous measurement of seawater pH and Total Alkalinity. The proposed research involves micro sensor development, electrochemistry, marine chemistry, and electrical engineering. Combination of two ISFET measurement principles will be used for rapid, sequential measurement of pH and Total Alkalinity in order to generate a full thermodynamic description of the CO2 system in the analyte solution.Broader Impacts: Making sensors to measure pH and total alkalinity in real time and at the appropriate precision is important to our understanding of ocean acidification. If successful, they plan to commercialize it. Other situations where total weak acid or base concentration in combination with the pH form useful information, this proposed system might be used, like in food industry and for biomedical applications. Two graduate students will be involved in this project.

PI 请求资助开发一种低功耗、自主固态传感器，用于同时测量海水 pH 值和总碱度。拟议的研究涉及微传感器开发、电化学、海洋化学和电气工程。两种 ISFET 测量原理的结合将用于快速、连续测量 pH 值和总碱度，以便生成分析物溶液中 CO2 系统的完整热力学描述。更广泛的影响：制造能够实时测量 pH 值和总碱度的传感器适当的精度对于我们了解海洋酸化非常重要。如果成功，他们计划将其商业化。在总弱酸或碱浓度与 pH 值结合形成有用信息的其他情况下，可以使用该系统，例如食品工业和生物医学应用。两名研究生将参与该项目。
