3D法线压痕映射
机械压痕是一种针对生物组织的快速且无损的评估技术。最近，Biomomentum改进并增强了该技术的制图能力，并且解决了垂直性问题，但仍在损害其他方法，例如纳米压痕。利用这些突破，新研究设计的效率大大提高了。压痕通常要求被测表面平坦，并且还要求压缩轴垂直于关节表面对齐。Mach-1 v500css多轴机械测试仪的3D“正常压痕”功能可检测表面在XY位置的高度和方向，并记录载荷（多轴载荷传感器），同时以不同的速度移动测试仪的三个阶段为了使带有预定位移轮廓的球形压头沿着垂直于样品表面的虚拟轴移动。利用Mach-1 v500css测试仪独特的多轴功能，Biomomentum开发出了新颖的功能，可实现压痕测试的所有优势，同时克服了传统的局限性。这一技术进步依赖于Mach-1 Motion软件的两个功能的增加：“ Scan XY”和“ Normal Indentation”。在每个位置执行一系列功能之前，“扫描XY”功能会在预定位置移动测试仪的X和Y水平平台。应该提到的是，使用Biomomentum的“软骨图”软件处理的样品的俯视图可以轻松生成这样的位置列表。“正常压痕”功能可检测表面在XY位置的高度和方向，并记录载荷（多轴载荷传感器），同时以不同的速度移动测试仪的三个阶段，从而以预定的速度移动球形压头沿垂直于样品表面的虚拟轴的位移曲线。应该提到的是，使用Biomomentum的“软骨图”软件处理的样品的俯视图可以轻松生成这样的位置列表。“正常压痕”功能可检测表面在XY位置的高度和方向，并记录载荷（多轴载荷传感器），同时以不同的速度移动测试仪的三个阶段，从而以预定的速度移动球形压头沿垂直于样品表面的虚拟轴的位移曲线。应该提到的是，使用Biomomentum的“软骨图”软件处理的样品的俯视图可以轻松生成这样的位置列表。“正常压痕”功能可检测表面在XY位置的高度和方向，并记录载荷（多轴载荷传感器），同时以不同的速度移动测试仪的三个阶段，从而以预定的速度移动球形压头沿垂直于样品表面的虚拟轴的位移曲线。
3D NORMAL INDENTATION MAPPING
Mechanical indentation is a rapid and non-destructive assessment technique for biological tissues. Lately, Biomomentum has improved and augmented this technique with both mapping capability and solving the perpendicularity problem still impairing other methods such as nanoindentation. Using these breakthroughs, the efficiency of new study designs has improved greatly. Indentation usually requires the tested surfaces to be flat and it also requires the compression axis aligned perpendicularly to the articular surface. The 3D “Normal Indentation” function of the multiaxial mechanical tester Mach-1 v500css precisely detects the height and orientation of the surface at the XY position and records the load (multiaxial load cell) while simultaneously moving the three stages of the tester at different speeds in order to move a spherical indenter with a predefined displacement profile along a virtual axis normal to the surface of the sample. Taking advantage of the unique multiple-axis capabilities of the Mach-1 v500css tester, Biomomentum has developed novel functionalities which allow all the advantages of indentation testing, while overcoming traditional limitations. This technological advancement relies on the addition of two functions to the Mach-1 Motion software: “Scan XY” and “Normal Indentation”. The “Scan XY” function moves the X and Y horizontal stages of the tester at predefined positions prior to performing a series of functions at each of these positions. It should be mentioned that such a position list can be easily generated using a top view picture of the sample processed with Biomomentum’s “Cartilage Mapping” software. The “Normal Indentation” function precisely detects the height and orientation of the surface at the XY position and records the load (multiaxial load cell) while simultaneously moving the three stages of the tester at different speeds in order to move a spherical indenter with a predefined displacement profile along a virtual axis normal to the surface of the sample.
