This book is based on the best contributions to the advancement of bioimpedance knowledge and use from the Latin American Congress series, CLABIO. Basic bioimpedance facts as well as promising and original contributions to bioimpedance theory and applications are presented, giving the reader stimulating material for reflection, decision making, and further experiments. Contributions come from a diverse international pool of experts and address topics on electrode and skin impedance modelling, tomography, spectroscopy, instrumentation, and clinical applications.

Franco Simini is Professor of Biomedical Engineering at the Universidad de la Republica in Montevideo, Uruguay, where he founded the 'Nucleo de Ingenieria Biomedica,' a joint project of the Faculty of Medicine and the Faculty of Engineering. 

Pedro Bertemes Filho is Professor of Electrical Engineering at the Universidade do Estado de Santa Catarina (UDESC), Brazil, since 2004, lecturing electronic instrumentation, sensors and transducers, and introduction of biomedical engineering for master and doctorate students.  He finished the Electrical Engineering undergraduate course in 1995 at UDESC. Master in Biomedical Engineering in 1998 at the Federal University of Santa Catarina (UFSC) and PhD in Medical Physics in 2002 at the University of Sheffield (UK). Leader of the biomedical engineering research group at UDESC. Pioneer on bioimpedance device in Brazil for clinical studies on cervical cancer screening. Member of IEEE, ISEBI, SBEB, IFMBE and ATINER. Peer reviewer over 10 international journals. Main areas of research interest are electrical bioimpedance, bioinstrumentation and biosensors.
