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.
