Abstract

A miniaturized multiaxial load cell was developed and calibrated to measure the main load components acting across the operated median sternum. The sheep was selected as the animal model for this project. The geometry of the core of the transducer was chosen to fulfill the requirements for a multiaxial load cell with miniaturized dimensions and with the constraints deriving from its installation on a resected sternum. A computer-controlled machine was used to mark the cylinder surface with the lines needed to position and align correctly the strain gauges. Then, the load cell was connected to the System 6000 data acquisition system in all the calibration series. Finally, the fully calibrated transducers were loaded by a multiaxial loading system to verify the overall accuracy of the load cell in the worst possible conditions. The accuracies of the custom-made load cells measured in the case of a five-component loading system were proven to be satisfactory.
