A Microcontroller-based instrument for prostheses osseointegration measurement by electrochemical impedance spectroscopy

A method based on Electrochemical Impedance Spectroscopy (EIS) for the diagnosis of prosthesis osseointegration was proposed by the Authors in previous works [1]-[2]. In this paper, the design, the implementation, and the metrological characterization of a microcontroller-based prototype conceived as a stand alone instrument to be used for in-vivo clinical applications are presented. The preliminary experimental results of laboratory evaluation are presented.
