 A concept for a 6 degree of freedom magnetic load cell is shown below.  It uses a pair of flexures (aluminum or titanium plates on top and bottom) to set relative stiffnesses of Fx, Fy, Fz, Tx, Ty, Tz.  A central rod carries a disk with four small neodymium magnets which moves when loads are applied.  Four AS5013 hall array ICs are positioned just below the rest positions of the magnets on a single PCB.  M3 standoffs and screws hold the entire stack together.

+Features of a "good" 6 DOF flexure:
+* Ability to tune relative stiffnesses (e.g. Fx/Fz, Tx/Tz, etc.)
+* Minimal cross talk (i.e., Fx doesn't induce a displacement in y or a twist, etc.)
+* Fits into a reasonably small bounding volume.
