Abstract

See full text

A resonance shear measurement device (1) of the present invention includes an upper unit (10) having a piezoelectric element (15), an upper disk substrate (16), and a spring (17), and a lower unit (11) having a lower disk substrate (14), in which a sample insertion portion (21) is formed between a lower surface of the upper disk substrate (16) and an upper surface of the lower disk substrate (14), the piezoelectric element (15) and the upper disk substrate (16) are vibratably connected to a fixed apparatus 30 via the spring (17), a strain gauge (19) is attached to the spring (17), and by applying an AC voltage to the piezoelectric element (15) while changing a frequency of the AC voltage, a response voltage at the resonance from the strain gauge (19) due to a vibration of the upper unit (10) is measured.
