The mechanical properties are indispensable parameter for evaluate the tissue structures. In this report, we developed a micro vacuum chuck which could fix the three-dimensional multilayered tissue to tensile test system without breakage of sample. The three-dimensional multilayered tissues were fabricated with technique of layer-by-layer (LbL) nanofilm coatings. By using the micro vacuum chuck, we succeeded to measure tensile force of the three-dimensional multilayered tissues. In the result, the maximum tensile force was about 626 μN (strain: 1.9). When maximum force occurred, the sample detached from the chuck. The profile of force-strain curve was similar to that of tendon or the ligament. This result indicates that the three-dimensional multilayered tissue has mechanical properties which are same to living tissues.
