Abstract: A piezoelectric finger (PEF) is a piezoelectric cantilever consisting of a driving and a sensing piezoelectric layer such as lead zirconate titanate (PZT) bonded to nonpiezoelectric layer, e.g., stainless steel. With the dual electrode design, a PEF can both apply a force and detect the resultant displacement with one single device. We have demonstrated that a PEF can measure both the elastic and shear moduli of tissues. Furthermore, we can locate and determine the size of a tumor non-invasively. By comparing the shear and elastic moduli of a tumor, we have the potential to differentiate malignant tumors from benign ones non-invasively. This unique ability of PEF stands to greatly aid tumor malignancy test accuracy.
