BiomomentumThe company focuses on the design and manufacturing of mechanical performance testers for organizations and biomaterialsOver the past 20 years, Mach-1 multifunctional 3D indentation tester has been designed as an integrated device for testing tensile, shear, friction, torsion, and 3D indentation mapping,veryFacilitating the scientific research work of researchersSince 1999, the multi axis mechanical testing system of MACH-1 has helped hundreds of scientists around the world enhance and publish innovative research related to biomaterials, tissues, and soft materials.

MACH-1 Multi functional 3D Indenter

--Mach-1 has a wide range of applicable samples, from hard tissue materials such as bone to extremely soft tissue materials such as brain tissue and cornea, from coarse intervertebral disc samples to extremely fine single fiber filaments. It can carry out precise and reliable 3D mechanical measurement and characterization for irregular surface samples such as biological tissues, polymers, gel, biomaterials, etc.

--MACH-1 is a multifunctional biomechanical and potential characteristic testing and analysis device for biological tissue materials that integrates various mechanical types such as tension, infinite compression, finite compression, shear, friction, 3D indentation mapping (for irregular surfaces), 2D contour, 3D contour mapping (for irregular surfaces), 3D thickness mapping, torsion, three-point bending, four point bending, cantilever bending, puncture force, tearing, fracture, adhesion (adhesive), blasting force, peeling force, impact force, injection pressure and suction force, swelling and contraction, lap shear force, mechanical electrical testing (compression simultaneous measurement of potential), and multiple force coupling.

--The mechanical properties that can be characterized include stiffness, strength, modulus, viscoelasticity, plasticity, hardness, adhesion, torsional force, and displacement.

indentationIt is usually required that the testing surface be flat and the compression axis be aligned perpendicular to the joint surface.Mach-1 Multi functional 3D IndenterofNormal indentationThe function can be accurately detectedThe height and direction of the XY position surface are recorded, and the load (multi axis weighing sensor) is recorded. At the same time, the three tables of the testing instrument are moved at different speeds, and the spherical indenter moves relative to the virtual axis perpendicular to the sample surface. By utilizing the multi axis function of Mach-1, it is possible to directly measure multiple surfaces without damaging the samplepointPerform indentation measurement and3D mapping.

Example of 3D indentation test:(Taking the tibial plateau of mouse knee joint as an example)

1Please followMapping Toolbox userSelect the sample holder for fixation, fix the sample as a whole on the sample holder and place it in the testing room.

2Manually connect the testing room toMach-1Up there. When performing this operation, locate the testing room/Sample to maximize the availability on the sampleX-YScanning range (usually,XThe scanning range of the direction isYTwice the direction).

3Image application: Scan the sample with a camera, import it into software, and create a grid of test point positions on the image.

4Reduce the spherical pressure head towards the surface（ZAxis), until the surface of the indenter is just above the highest point of the specimen surface, approximately2 mmHere. Translate into EnglishZSet the position to zero. Suggest moving the horizontal workbench (using manual control) to verify that the pressure head cannot come into contactXYScan all sample surfaces within the scanning area, otherwise it may damage the sensor head.

5At this point, relevant files can be created on the computer through software,XYZAxis coordinate zero point, testing frequency and other parameters.

useMapping ToolboxRelated protocols (file name, sample holder type, mapping dimension annotation method, surface positioning template, and positioning mesh), creating blank spaces for the surface“filename.map”Document.“Filename.jpg”The image will also be automatically created. Then according toMapping ToolboxThe method of dimensioning images; create“Filename-Indentation-Mach-1 XY Positions（i）.map”Document.

6If you need shower gel, use enoughPBSFill the laboratory with solution to cover at least the highest point of the sample1Centimeters, and at least leave enough space15Balance in minutes.

7, using manual control“Zero load”Function execution with zero load.

8After all parameters and files are set, the motor in the computer performs indentation testing, and the spherical indenter will automatically test based on the image grid and settings. After all grid points are tested, the test ends.

9If the sample is too large, it can be movedXYAfter the axis, reposition the testing area and overlay the results with those before repositioning.

10Data analysis can obtain the hardness distribution and elasticity data of the entire tibial plateau surface based on the measurement results and indentation data, and draw a colored hardness distribution map.
