The wafer disc clutch is mounted on the femoral link (A) just above the four-bar linkage (B) coupling with the tibial link (C). Oil-sintered bronze bushings (D) on the bottom cover allow the clutch to float relative to the brace. The flat motor (E) actuates the pressure plate (F) through ballscrew mechanism (G), thus applying a normal force to the wafer disc stack (H). The wafer discs are alternately coupled to the stator (I) and the rotor barrels (J) through nylon keys (K). When engaged, the clutch transmits torque from the worm gear (L) to the crank arm (M) and thus to the tibial link. The rotor barrel position is sensed by the string potentiometer (N), while a Hall effect sensor is used to estimate the vertical position of a magnet (O) fixed to the pressure plate. https://images.squarespace-cdn.com/content/v1/5ab1a73c372b969a6e793dbf/1543456066179-QOJIAZE99VV4YT9MB8R6/fig10.PNG ETH Knee Perturbator Figure 10 - Signal conditioning circuitry located on the ETH Knee Perturbator. https://images.squarespace-cdn.com/content/v1/5ab1a73c372b969a6e793dbf/1543454373876-1JWX9ET0IV0JDPM7P3DY/fig6.PNG ETH Knee Perturbator Figure 6 - Instrumentation of the crank arm used to measure torque.
