Abstract: This invention provides an extremely accurate way to characterize the Young's modulus of thin film materials with thicknesses in the nanometer range. It takes advantage of a recently developed high Q silicon Young's modulus resonator (YMR), which has a record high quality factor of about fifty million in operation at temperatures below 10 degrees Kelvin (10K). Because of the high Q of the YMR, the temperature stability of the YMR's resonance frequency below 1K, and the extremely high degree of vibration isolation inherent in the inventive design, the relative resolution of the resonant frequency is typically in 2×10−7. This is enough to resolve a resonant frequency shift after a deposition of a thin film onto the sensitive part of the resonator, and to compute the Young's modulus of thin film materials of even a few monolayers thickness.

The method comprises coupling a broad-band actuator to the composite material and connecting sweeping frequencies to the broad-band actuator for vibrating the composite material. An acoustic sensor is coupled to the composite material for measuring a resonant frequency curve of the vibrating composite material. The measured resonant frequency curve of the vibrating composite material is compared with a reference resonant frequency curve. A delaminated composite material produces a change in the measured resonant frequency curve relative to the reference resonant frequency curve.

Abstract: Provided is an apparatus for assessing interface integrity between a medium and an implant. A first signal is translated from a motion of an impact body during impact with an abutment connected to the implant. In some embodiments, the first signal is filtered using a zero phase shift filter and then used for assessing the interface integrity. Since no phase shift is introduced, the interface integrity is accurately assessed. In another embodiment, the apparatus maintains a system model for impacting the impact body against the abutment. The apparatus analytically determines an interface property by applying a system property that has been determined to the system model. An accurate system model allows for an accurate assessment. According to another broad aspect, there is provided a method of conducting the impact test. According to the method, a person ensures that the impact body impacts against a consistent portion of the abutment.

Abstract: There is provided a method for testing a piezoelectric/electrostrictive actuator, wherein the displacement of a piezoelectric/electrostrictive actuator is estimated on the basis of the relations between one or more frequency characteristic values selected from the group consisting of the heights and areas of the peaks of the resonance waveforms and the difference of the maximum and minimum of the first order or first to higher orders of the resonance frequency characteristic values of the piezoelectric/electrostrictive actuator and the k-th order (k=1 to 4) of the first or first to higher orders of resonance frequencies.
