transducer for quantifying torsion

Hi All,
I am looking for a implantable transducer, which can measure the torsion of a tendon.
Can implantable force transducers measure this? I read in a tissue engineering book (Chapter by An) that depending on the shape (S or E) the buckle transducer can measure shear. I tried looking for the details of this in the references but was not successful.
any one who can guide/ help me with this??
