提出了一种基于局部应变传感的结构材料损伤检测方法，并验证了其有效性。作为应变传感器，压电聚合物被涂覆在铝板表面。用带扫描探针的运算放大电路测量了10思乐试样中的局部应变，并在扫描电子显微镜下用电压衬度技术观察了局部应变。初步结果表明，这些方法使用压电聚合物是敏感的和有用的检测和测量局部静态应变的结构材料。
Local strain sensing methods are developed for damage detection in structural materials, and their validities are demonstrated. As strain sensors, piezoelectric polymers were coated on the surfaces of aluminum sheets. Local strains in the ten sile tested aluminum sheets were measured by an operational amplifier circuit with a scanning probe, and then observed using the voltage contrast technique in a scanning electron microscope. The preliminary results indicate that these methods using piezoelectric polymers are sensitive and useful for detection and measurement of local static strains in structural materials.
