SGER: Integrated Microelectrode Arrays for Field-Based Environmental Monitoring

0228603 Papautsky该项目的目标是开发一种新型的自给式微电极，可用于环境中监测受污染土壤和沉积物中的各种成分。这些设备将由与微电子信号处理器紧密连接的微电极组成，以降低噪声并增强稳健性。这些设备最终将包括一个发射器，将信息遥测到传统的数据存储设备，并将由微型电池供电。提出的研究目标有三个：(1)发展集成微电极的基础科学；(2)设计和制造微处理器，处理和放大来自微电极的信号；(3)利用概念验证传感器展示用于环境监测的集成微电极阵列。如果成功，该项目将在美国数千个危险废物处理场受益，这些废物需要监测土壤、沉积物和地下水中的各种成分，包括有毒或危险物质和环境参数。

0228603PapautskyThe objective of this project is to develop a new breed of self-contained microelectrodes that can be used in the environment to monitor a variety of constituents in contaminated soils and sediments. These devices will consist of a microelectrode intimately connected to a microelectronic signal processor to reduce noise and increase robustness. These devices will ultimately include a transmitter to telemeter the information to a conventional data storage device and will be powered by a miniature battery. The goals of the proposed research are threefold: (1) develop the fundamental science to microfabricate the integrtated microelectrodes, (2) design, and fabricate, a microprocessor to process and amplify signals from the microelectrodes and (3) demonstrate integrated microelectrode arrays for environmental monitoring using proof-of-concept sensors. If successful, this project will have benefit at the thousands of hazardous waste sites in the US that require monitoring of the soils, sediments and ground waters for a variety of constituents, including toxic or hazardous materials and environmental parameters.
