Influence of electrodes on the 448 kHz electric currents created by radiofrequency: A finite element study

Autor: Antonio Hernando, C. Gonzalez de Vega, M. Buenaventura, J. Spottorno

Publikováno v: Electromagnetic Biology and Medicine. 36:306-314

Radiofrequency is a technology used in physical rehabilitation by physicians and physiotherapists for more than fifteen years, although there exist doubts on how it works. Indiba is a particular method that applies a voltage difference of 448 KHz bet

We present here a study of the possible local heating effects in surface plasmon resonance sensors using low power lasers (∼mW/mm 2 ). By measuring the increase of electrical resistivity in an Au stripe while exciting SPR and performing numerical s

In vivo measurements of electrical conductivity of porcine organs at low frequency: New method of measurement

Autor: Marta Multigner, G. Rivero, L. Alvarez, M. Santos, J. Spottorno, J. de la Venta

Publikováno v: Bioelectromagnetics. 33:612-619

Calculations of the induced currents created in the human body by external electromagnetic fields would be more accurate provided that more realistic experimental values of the electrical properties of the body were available. The purpose of this wor

Magnetic Sensor for Early Detection of Heart Valve Bioprostheses Failure

Autor: Antonio Hernando, I. Carabias, J. Valdés, G. Rivero, J. M. García-Páez, J. Spottorno, Marta Multigner, L. Alvarez

Publikováno v: Sensor Letters. 5:263-266

(Received: xx Xxxx xxxx.Accepted: xx Xxxx xxxx) Heart valve bioprostheses usually do not need anticoagulation; however they are threatened by an increasing with time risk of degeneration. The aim of this work is to find a magnetic sensor, which could

Short-term fatigue testing can predict medium-term pericardium behaviour

Autor: Lourdes Alvarez, J.M. García Páez, Rafael Claramunt, Antonio Ros, J. Spottorno, María Concepción Casado

Publikováno v: Journal of the mechanical behavior of biomedical materials. 4(8)

The medium-term fatigue behaviour of calf pericardium (similar to the one used to manufacture cardiac bioprostheses valve leaflets) has been studied. 96 samples were tested under fatigue subjecting them to biaxial stress at 1 Hz frequency for 5000 cy
