Taking advantage of their characteristic, we fabricate a multi-layered cross-shaped piezoelectric sensor for torsional load analysis. It consists of a polyethylene terephthalate substrate and two piezoelectric layers placed in the crossed form. From the crossed shape of two piezoelectrics, various conditions of torsional loading can be analyzed by simply measuring load voltage amplitudes and phases. We derive a modeling framework of the cross-shaped piezoelectric sensor under torsional loading to expect the sensing response of the sensors. Also, an experimental setup is established to verify the modeling statement.
