    • A device designed to apply uniaxial pressure to the surface of an electro-active material while simultaneously applying a current to the material under controlled temperature conditions and then measuring the displacement of the material by means of a laser interferometer. The device involves a housing with a chamber in which a sample of material is secured. The chamber has an aperture with a quartz window that allows the laser beam from the interferometer to pass. The sample is connected to electrodes and the chamber is filled with dielectric oil that applies the uniaxial pressure to one side of the sample. The device is placed onto a thermal control system. When the appropriate thermal and pressure conditions are established, current is applied to the sample and the interferometer measures the displacement.
    • 设计成将单轴压力施加到电活性材料的表面上的装置,同时在受控温度条件下同时向材料施加电流,然后通过激光干涉仪测量材料的位移。 该装置涉及具有室的壳体,其中固定有材料样本。 该腔室具有允许来自干涉仪的激光束通过的石英窗口的孔。 样品连接到电极,并且腔室填充有将单轴压力施加到样品的一侧的介电油。 该装置放置在热控制系统上。 当建立适当的热和压力条件时,将电流施加到样品,并且干涉仪测量位移。

    • A specialized containment cell with optically transparent apertures, in conjunction with a laser interferometer system provides the means for non-contact displacement measurements of electro-active (piezoelectric and electrostrictive) materials to be performed under controlled conditions of pressure, temperature and applied voltage. A sample of electro-active material is placed inside the cell. Electrical connections are made from a high voltage power source to the sample through the cell. Thermoelectric heaters/coolers and a cooling water heat sink built into the cell control the temperature of the sample. The cell is flooded with a dielectric oil pressurizing the interior of the cell to a desired pressure. The cell is optically aligned to the interferometer, and with the cell heated to the proper temperature, a voltage is applied to the sample as the interferometer measures the displacement of the sample.
    • 具有光学透明孔径的专门的容纳单元与激光干涉仪系统结合,提供了在受压力,温度和施加电压的受控条件下进行的电活性(压电和电致伸缩)材料的非接触位移测量的装置。 将电活性材料的样品放置在电池内。 电连接由高压电源通过电池连接到样品。 热电加热器/冷却器和内置于电池中的冷却水散热器控制样品的温度。 电池充满了将电池内部加压至所需压力的介电油。 细胞与干涉仪光学对准,并且随着细胞被加热到适当的温度,当干涉仪测量样品的位移时,将电压施加到样品。
