摘要： Systems and methods are disclosed for sensing forces, moments, temperature, inclination, acceleration and other parameters associated with prosthetic limbs. The system is capable of measuring forces in three designated axes, and moments about the same designated axes, for a total of six possible degrees of freedom. The system can be readily fitted onto a conventional prosthetic limb with no, or relatively minor, modification thereto. A plurality of sensor arrays are disposed on a support member, each array including a plurality of strain gauge sensors, each sensor outputting an electrical signal responsive to loading imposed on the support member through the prosthetic limb. Electronic circuitry in communication with the gauges is operative to receive the electrical signals from the strain gauges and provide a signal useful in the form, fit or function of the prosthetic limb. The strain gauges are configured to generate positive and negative (signed) voltages to determine moments, shear forces and off-center loading. The inclinometers may be used to simulate a goiniometer. An unaffected limb electronics package and data collection module are disclosed to achieve an intelligent prosthetic endo component system.
