Mo The video above shows a printed test of an exagerrated flexure (so that we can see the deflection). I've also printed some much stiffer flexures which translate in a range measureable by a differential hall effect pair. +### 2 DOF Force + Moment + +After talking to Ian about the requirements of a 2 degree of freedom load cell for a prosthetic ankle application, here was a quick sketch of a flexure and layout of magnets and sensors. + +<img src='ankle-2dof/ankle-2dof-sketch-1.png' width=300px> +<img src='ankle-2dof/ankle-2dof-sketch-2.png' width=300px> + +The two sensors can differentiate forces in the Z direction and moments around the X axis (out of the screen). + +<img src='ankle-2dof/ankle-2dof-sim-force.png' width=300px> +<img src='ankle-2dof/ankle-2dof-sim-moment.png' width=300px> + +
