Patent ID: 8132446

Claim:
A property measurement apparatus comprising: a first plate installed in a state of being rotatable and/or vibratable; and a second plate placed to face said first plate and provided with an impedance measurement section, wherein a stress caused by a distortion generated by rotating or vibrating said first plate to serve as a distortion given to a sample provided in a gap between said first and second plates is measured, at a same time, said impedance measurement section measures the impedance of said sample; an insulation layer; a pair of conductive layers facing each other to sandwich said insulation layer and each functioning as a high-frequency transmission line; a layer breaking gap which is formed on said conductive layer on a side close to said first plate to break said conductive layer and allows a portion of said sample to be introduced thereto; a voltage is applied between said conductive layers, and an impedance which may change due to introduction of said sample to said layer breaking gap is measured.
