This paper suggests a poly(vinylidene fluoride) (PVDF) piezoelectric diaphragm actuator used in a novel fatigue test method for thin metal films. A thin-film metal specimen is stamped on top of the actuator using a stamping epoxy. As the actuator vibrates, the stress in the specimen increases until it fails under fatigue. A finite element model of the actuator is built, and its vibration amplitude is confirmed to be in a good agreement with experiment. Then, a model of the specimen is added to this model to simulate the vibration of the specimen for fatigue test. Stress analysis of the specimen at a driving voltage of 200 V0-p confirms that this actuator can increase the stress in the specimen to near 1 GPa, which is high enough for the fatigue test of metals such as titanium. In the experiment, a thin-film titanium specimen is stamped on top of the actuator which is then vibrated. The stress in the fatigue gauge on thin-film specimen increased until the specimen failed under fatigue. This shows that the proposed PVDF actuator is suitable for the fatigue test of thin-film metals such as titanium. © 2012 Institute of Electrical Engineers of Japan.

Combinatorial search is one of the useful methods that could search for optimal composition of alloy materials or novel alloy materials. Combinatorial sputtering provides sample group (library) having different compositions in a limited place. Then, the properties of the samples can be scanned in an efficient way. In this research, it was studied that magnetostrictive material with high magnetostriction, relative permeability and resistivity. Desired value of magnetostriction is more than 20×10-6, relative permeability is more than 4000, and resistivity is more than 100 µΩ·cm. As a result, composition that Cr content is less than 14 at.% fill the desired value of relative permeability, and more than 10 at.% fill the desired value of resistivity. There is possibility to fill the desired value of magnetostriction.

Thin film shape memory alloys (SMAs) are promising materials for micro-machines because of their high-output power, large strain, and actuation without high voltage. To search for compositions of suitable thin film SMAs for each application, combinatorial technique is useful tool, however the technique requires high-throughput characterization method for thermal property which is an important property of thin film SMAs such as two way martensitic transformation temperature and thermal hysteresis. In this paper, novel high-throughput characterization method for such properties using thermography is proposed and demonstrated. Compositionally integrated thin film SMA samples (TiNiPd) with only 1mm2 of each area are characterized at once. The difference of martensitic and reverse martensitic transformation temperature against those temperatures measured by a conventional method, differential scanning calorimetry, is about 5K.
