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.

Abstract: A force-measuring device testing system 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. The load cell is configured to impart a time-varying applied force to the sample which includes a force-measuring device. A load cell signal processing circuitry is configured to measure force signals at the load cell and output amplified force signals to the controller. The controller is configured to repeatedly carry out the following until a desired force trajectory has been executed: (1) calculate digital force signals in accordance with the amplified force signals, (2) calculate a next actuation of the Z-axis actuator in accordance with a desired force trajectory and an elastic parameter, and (3) control the actuation of the Z-axis actuator in accordance with its next calculated actuation.
