“…Thus, various analytical methods available in literature [ 40 , 41 ] are not suitable for investigating the response of an eddy current sensor implanted inside the human body. Therefore, full wave analysis by numerical methods is frequently employed [ 42 , 43 , 44 , 45 ].…”

Joint replacement surgeries have enabled motion for millions of people suffering from arthritis or grave injuries. However, over 10% of these surgeries are revision surgeries. We have first analyzed the data from the worldwide orthopedic registers and concluded that the micromotion of orthopedic implants is the major reason for revisions. Then, we propose the use of inductive eddy current sensors for in vivo micromotion detection of the order of tens of μm. To design and evaluate its characteristics, we have developed efficient strategies for the accurate numerical simulation of eddy current sensors implanted in the human body. We present the response of the eddy current sensor as a function of its frequency and position based on the robust curve fit analysis. Sensitivity and Sensitivity Range parameters are defined for the present context and are evaluated. The proposed sensors are fabricated and tested in the bovine leg.

. Artículo Investigación RESUMEN: En este trabajo se describe un método para caracterizar la conductividad eléctrica de tubos metálicos sin hacer contacto con ellos. Se utiliza un circuito LC, a baja frecuencia, para detectar el cambio de inductancia debido a la presencia del conductor en el núcleo de la bobina. Así mismo, se implementa un instrumento virtual en LabVIEW para medir los cambios del promedio de la potencia instantánea en la bobina a partir de las mediciones de corriente y voltaje cuando diferentes materiales conductores se disponen en su núcleo.PALABRAS CLAVE: Conductividad eléctrica, circuito LC, circuito RLC, frecuencia de resonancia, promedio de potencia instantánea, LabVIEW.ABSTRACT: This work aims to present a method to characterize the electrical conductivity of metal tubes without making contact with them. A LC circuit is implemented to detect the change in the inductance due to the conductor material within the coil. Moreover, a virtual instrument created in LabVIEW is implemented for calculating the average value of instantaneous power of the inductor by measuring the current and the voltage when different conductor tubes are placed in the core.
