A PEFS (Piezoelectric Finger Sensor) acts as an 'electronic finger' capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. The PEFS may be incorporated into a portable hand-held device. The PEFS offers superior sensitivity.
