Abstract:
The study describes the development of autonomous portable electrochemical sensing systems for environmental and bio applications by few examples of custom-designed systems. They include a swallowable capsule with wireless communication link for in-vivo gastrointestinal track investigation, an automatic chemical sensing system operating on-board of a robotic fish for detection pollution and monitoring of the water quality in seaport areas and multichannel electrochemical sensing instrumentation with fluidic control of flow-through system for screening the impact of nanomaterial on human health and the environment. The described apparatuses represent complete sensing systems comprising of a portable low-noise anolog front-end under microcontroller regulation which work in pare with a control PC equipped with corresponding signal processing software for handling the signal from a silicon microfabricated chip-based electrochemical sensors tailored to application specification and requirements. Key principles of the system design are considered and the systems operation and performance are discussed.
