An activated enzyme electrode for creatinine
Analytica Chimica Acta, 1976Abstract A highly selective enzyme electrode for creatinine, based on tripolyphosphate-activated creatininase enzyme, is described and evaluated. Kinetic studies comparing purified creatininase enzyme in the activated and non-activated forms show that the activation mechanism involves an increase in V max but no change in K m .

Nanoimpacts at Active and Partially Active Electrodes: Insights and Limitations
Angewandte Chemie, 2020AbstractWhile the electrochemical nanoimpact technique has recently emerged as a method of studying single entities, it is limited by requirement of a catalytically active particle impacting an inert electrode. We show that an active particle‐active electrode can provide mechanistic insight into electrochemical reactions.

IEEE Transactions on Industrial Electronics and Control Instrumentation, 1970
The need for reliable, easily applied, dry electrodes for use in medical applications has prompted investigation in many directions. Most wet or paste type electrodes are not only irritating to the skin when used over long periods of time, but also require careful skin preparation for clinically useful results. An insulated electrode technique has been

High and dry? Comparing active dry EEG electrodes to active and passive wet electrodes
Psychophysiology, 2016AbstractDry electrodes are becoming popular for both lab‐based and consumer‐level electrophysiological‐recording technologies because they better afford the ability to move traditional lab‐based research into the real world. It is unclear, however, how dry electrodes compare in data quality to traditional electrodes.

Activated carbon paste electrodes for biosensors
Analytical Chemistry, 1994A reagentless amperometric glucose biosensor was constructed using glucose oxidase and hydroquinone (H2Q) coimmobilized in carbon paste. The sensor response was studied by amperometry and cyclic voltammetry in quiescent solutions, as well as in a flow injection apparatus.

Bioamplifier using active electrodes
2020 IEEE 21st International Conference on Computational Problems of Electrical Engineering (CPEE), 2020The specialized bioamplifier for active electrode applications is presented in this paper. Our device presents 4 channeled bioamplifier with option to connect 3 couples of active electrodes and one couple of standard electrodes. The measured signal processing and digitalization are based on the ADS1194 chip by Texas Instruments.

Laplacian electrocardiograms with active electrodes
Proceedings of the 1997 16 Southern Biomedical Engineering Conference, 2002Laplacian electrocardiograms (ECG) were acquired with excellent signal to noise ratio (SNR). The signal locates the moment of activation (MOA) at an electrode site from the surface of the chest. A tripolar concentric ring electrode provides a small but well-defined localized signal with high common mode rejection (CMR).

A Redox‐Active Binder for Electrochemical Capacitor Electrodes
Angewandte Chemie, 2016AbstractA promising strategy for increasing the performance of supercapacitors is proposed. Until now, a popular strategy for increasing the specific capacity of the electrode consists of grafting redox molecules onto a high surface area carbon structure to add a faradaic contribution to the charge storage.

Electrodes with Activated Pyropolymer Coatings
Journal of The Electrochemical Society, 1986The development of electrode coatings based on conducting activated pyropolymers has been actively persued at ELTECH Electrosearch laboratory since 1978. The activated pyropolymer coating is obtained by controlled thermal treatment, starting from solutions of pyropolymer precursors such as polyacrylonitrile (PAN) and catalysts precursors such as noble ...

Activation of solid electrodes
Electroanalysis, 1992AbstractThe mechanical and physicochemical techniques for activation of solid voltammetric electrodes—that is, polishing, chemical, and electrochemical treatment and modification of the electrode surface by heat or electromagnetic radiation—are briefly surveyed and critically evaluated.
