A simple model for the simulation of ultrasonically induced electric potentials

Although ultrasonically induced electric potentials in bone may play an important role in the bone formation and remodeling process, many aspects of the bone's weak piezoelectricity are still unclear. Most of the previously conducted studies consider a biological rather than electrical perspective. In this study, the ultrasonically induced electric potentials were experimentally measured by the bone transducer, and then compared to those numerically derived. To better understand the mechanoelectrical response of bone, a simple model for the simulation of ultrasonically induced electric potentials is here proposed. This model allows a quantitative analysis of the ultrasonic effects on bone, to investigate some of its interesting properties, such as inhomogeneity. The equivalent circuit parameters were obtained by linear and least squares method fitting, and proved to give a reasonably accurate, effortless simulation.
