Fabrication of arc-shaped 3D electrodes for biomedical devices

2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013
We developed a simple, low-cost and novel method for constructing three dimensional (3D) microelectrodes in biomedical devices by utilizing low melting point metal alloy. Three dimensional electrodes have unique properties in biomedical applications such as cell lysis, electroporation, dielectrophoresis, and detection.

Impedance Characterization and Modeling of Electrodes for Biomedical Applications

IEEE Transactions on Biomedical Engineering, 2005
A low electrode-electrolyte impedance interface is critical in the design of electrodes for biomedical applications. To design low-impedance interfaces a complete understanding of the physical processes contributing to the impedance is required. In this work a model describing these physical processes is validated and extended to quantify the effect of

Capacitive Type of Biomedical Electrode

IEEE Transactions on Biomedical Engineering, 1970
A suitable dielectric for a capacitive biomedical electrode is presented. In application a thin (2-mil) film of pyre varnish is deposited on the electrode surface and heat cured. Capacitance values of 800 pF for a 0.5-inch-diameter electrode are typical.

Numerical Modelling of Capacitive Electrodes for Biomedical Signals Measurement

2021 44th International Convention on Information, Communication and Electronic Technology (MIPRO), 2021
Surface electromyography (sEMG) uses noninvasive technique of measuring muscle action potentials on the skin surface. Numerical methods are often the first step in such a process of electrodes and biomedical electronic systems design. Thoughtful simulation, that precedes physical implementation, may speed up the product development, foreseeing its ...

Development of a miniaturepCO2 electrode for biomedical applications

Medical & Biological Engineering, 1975
A miniaturepCO2 electrode for possible CO2 measurement in a biological system was constructed and evaluated. ThepCO2 electrode employed a miniature pH glass electrode and the Severinghaus configuration. The electrode was evaluated in both gas and liquid phases. A good linear relation existed between the measured electrode potential of thepCO2 electrode
