Abstract
A probe has a vibration excitor including a core member made of a giant magnetostrictive material and magnetic field generation means for generating an alternating magnetic field having a randomly varying frequency to thereby expand and compress the core member to generate random vibration therein, and an impedance head for detecting an acceleration of the random vibration and a vibration stress created in organism tissue vibrated by the vibration excitor and generating electrical signals proportional thereto. A viscoelasticity measurement device using the above probe for the organism tissue is also disclosed.
