I need to identify some sort of pressure sensor(s) with which to be placed at specific anatomical read-points along the Exo-frame:
1. Inner wrist for biceps contraction
2. Outer wrist for triceps contraction
3. Mid-biceps for shoulder raise
4. Just above elbow for rear shoulder raise
5. Upper knee for hip raise
6. Rear lower-leg for hip swing back
Need to be able to set a threshold for the sensors for each position’s EoCL (Edge of comfort level). If the threshold is not triggered, the joint remains un-actuated and under the pilot’s power. Or perhaps some variant of this method that proportionately increases the actuator power with the amount of force registered by the sensor. This selective passivity will allow for a greater amount of power conservation and employ more natural stored energy release for things like the Contra-Postal walk that kind of feeds itself energy via the spinal torsions, arm swing and hip swing.
Any assistance would be greatly appreciated.

Note: the actuators will be Hydraulic-Electric Linear (Stepper motor) type.
