This dissertation by Malcolm Latorre focuses on the development and evaluation of a physical axon potential generator, known as the Paxon, for standardized testing of medical electrodes. The work aims to improve the understanding of electrode interactions with biological tissue, specifically in applications like deep brain stimulation (DBS). The Paxon simulates physiological action potentials using a test platform of 40 gold wires, each representing a node of Ranvier, to evaluate electrodes such as ECG surface and DBS types. The study includes a theoretical comparison of single and double cable neuron models to assess their effectiveness in DBS applications, emphasizing model complexity, axon diameter flexibility, and computational efficiency. The research targets biomedical engineers and healthcare professionals involved in electrode development and evaluation, providing insights into optimizing electrode design and functionality in medical applications.

This dissertation by Sami Abdelfatah Ibrahim Elhag explores the development of scalable, low-cost synthesis methods for metal oxide-based electrodes with applications in sensing and energy conversion. The research focuses on chemically modifying metal oxides such as cobalt oxide, zinc oxide, and bismuth zinc vanadate to enhance their performance in energy conversion processes and chemical sensing for analytes like dopamine, glucose, and glutamate. The electrodes are fabricated using a low-temperature wet-chemical approach, with characterization performed through techniques like X-ray diffraction and electron microscopy. The study demonstrates that doping with organic additives improves electrode efficiency by affecting the growth and conductivity of metal oxide nanocrystals. The work aims to advance the development of functional materials with controlled morphology for improved energy conversion and sensing capabilities.

This doctoral thesis by Kosala Wijeratne explores the use of conducting polymer electrodes in thermogalvanic cells (TGCs) as an alternative to traditional platinum and carbon-based electrodes. The research focuses on the conversion of thermal energy into electrical energy using iron-based molecules in aqueous electrolyte solutions. The study investigates the role of electrolyte viscosity, the mechanisms limiting electrical power output, and the electron transfer processes at the interface between the polymer electrode and the redox molecule. The findings aim to enhance the efficiency and application of conducting polymer cells in various technologies such as fuel cells, redox flow batteries, and dye-sensitized solar cells.

The material of this Symposium held at Mátrafüred (Hungary), 23-25 October, 1972, gives a survey on the most recent results obtained by means of ion-selective electrodes. The plenary lectures report mainly on the fundamental and theoretical examination of the different electrode systems together with their practical application. They give accounts of recent ex^perimental results obtained with precipitate based solid and organic ligand based liquid membrane electrodes as well as heterogeneous polythene membrane electrodes regarding their sensitivity, selectivity and response time. Examples are given to illustrate the application of the elctrodes in continuous analysis and measurement of ion activity. The factors influencing the electrochemical behaviour of the electrodes are also discussed. The topic of the discussion lectures is mainly the presentation of specific analytical results and the new types of electrodes. The results described in 7 plenary and 10 discussion lectures are completed by the summary of the conference discussion.

Reflects on developments in noninvasive electromyography, and includes advances and applications in signal detection, processing, and interpretation The book presents a quantitative approach to the study and use of noninvasively detected electromyographic (EMG) signals, as well as their numerous applications in various aspects of the life sciences. Surface Electromyography: Physiology, Engineering, and Applications is an update of Electromyography: Physiology, Engineering, and Noninvasive Applications (Wiley-IEEE Press, 2004) and focuses on the developments that have taken place over the last decade. The first nine chapters deal with the generation, detection, understanding, interpretation, and modeling of EMG signals. Detection technology, with particular focus on EMG imaging techniques that are based on two-dimensional electrode arrays are also included in the first half of the book. The latter 11 chapters deal with applications, which range from monitoring muscle fatigue, electrically elicited contractions, posture analysis, prevention of work-related and child-delivery-related neuromuscular disorders, ergonomics, movement analysis, physical therapy, exercise physiology, and prosthesis control. . Addresses EMG imaging technology together with the issue of decomposition of surface EMG. Includes advanced single and multi-channel techniques for information extraction from surface EMG signals. Presents the analysis and information extraction of surface EMG at various scales, from motor units to the concept of muscle synergies. The book is aimed primarily to biomedical engineers, rehabilitation physicians, and movement scientists. However, it may be appreciated by neurophysiologists, and physical and occupational therapists with a background in physics, engineering, and signal processing.
