Abstract
Example embodiments may relate to a compliant force sensor used in actuated and non-actuated systems. For instance, a structure (e.g., a transmission) may be configured to receive a force based on application of a load to the structure. A rigid member may be coupled to the structure and configured to provide a first deformation based on application of the load to the structure and transfer of the force to the rigid member. An elastic element may provide compliance and may be connected to the rigid member such that the rigid member is configured to further transfer the force to the elastic element. The elastic member may be configured to provide a second deformation under application of the load that is larger than the first deformation. A sensor may be positioned on the rigid member and configured to measure the first deformation independent of hysteresis and non-linearity in the elastic element.
