研制了一种能在体外同时测量二维生物膜（如血管壁、肠系膜或皮肤）的各向异性动态粘弹性模量的测试装置。这些测量可以作为频率（0·5 Hz至15 Hz）和初始二维应变（对于3×3 cm的试样，在延伸率λx和λy从1·005至2·3的范围内变化）的函数进行。在两个方向上的周期性变形的幅度相当于未变形尺寸的0.25%。
A testing device has been developed which simultaneously measures,in vitro, the anisotropic dynamic viscoelastic moduli of bidimensional biological membranes such as the vascular wall, mesentery or skin. These measurements can be carried out as a function of the frequencies (0·5 Hz to 15 Hz) and the initial bidimensional strains (in a range of extension ratios λx and λy varying from 1·005 to 2·3 for a 3×3 cm specimen). The amplitude of the periodical deformations in both directions amounts to 0·25 percent of the undeformed dimensions.
