 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.

+The two sensors can differentiate forces in the Z direction and moments around the X axis (out of the screen).
