Special Issue Information

Dear Colleagues,

The scientific approach to electrical impedance of chemical and biological environments has already been explored for more than a century. During the first decades of the last century, Peter Debye and Hugo Fricke derived a mathematical treatment for the frequency dependence of electrochemical and bioelectrical impedance. Since then, thousands of scientists and engineers have further developed both a theoretical understanding and a practical treatment of electrical bioimpedance. Their results are believed to be greatly promising for practical applications, especially in experimental biology and medicine.

We have experienced successful implementations of bioimpedance-based sensing technology in rate adaptive cardiac pacemakers, in cardiopulmonary analyzers and lung tomography devices, cell counters and analyzers. Unfortunately, the results of these were not as convincingly successful as expected. This is highly concerning. The implementation process has slowed down, for the following reasons.

First, we do not know enough about the distribution of electrical current in living tissues with variable parameters changing due to breathing, heart beating, blood oxygenation and circulation. Second, we do not know enough about the spectral and spatial distribution of the permittivity in living structures and their capacitive characteristics. Third, we do not know enough about the role of magnetic properties of tissues on their electrical impedance.

From an engineering point of view, we need more efficient configurations of sensing electrodes and materials in this respect, especially for microelectrodes. Contactless sensing methods and circuits are of interest. The deeper developed signal processing and data handling methods, together with including artificial intelligence algorithms, can give impressive results when it comes to obtaining new data, information and knowledge about living organisms.

Above highlighted and other theoretical and experimental developments, leading to practical implementations, are welcome in the Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
