Abstract
A system for mapping data of force transmission from a plurality of force-imparting points to each force-measuring device is disclosed. A linear actuator assembly includes a Z-axis actuator and a slider. A load cell is secured to the slider, such that actuation of the Z-axis actuator is mechanically coupled to a vertical movement of the load cell via the slider. A sample stage includes a sample stage positioner and is configured to retain a sample including at least one force-measuring device. The load cell is configured to impart a time-varying applied force to the sample. The controller is configured to control actuation of the sample positioner to position the load cell at each one of a plurality of force-imparting points on the sample and, for each respective force-imparting point, control the actuation of the Z-axis actuator. A computer is configured to generate a map of data of force transmission from the plurality of force-imparting points to the force-measuring device in accordance with digital transducer data obtained from the force-measuring device upon the imparting of the time-varying applied force at each force-imparting point.
