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.
