Faysal Haque

Faysal Haque has experience in manufacturing processes, mechanical testing, and machining. He completed his Masters in Mechanical Engineering from Miami University. His research work was focused on the ultralow wear rate of the metal filled fluropolymer composites for dry sliding applications. Prior to his Masters, he worked in a leading manufacturing plant as a process engineer. His research interest is in the biomechanics of soft-tissue and their different mechanical failures. Faysal Haque works as a Research Associate both for Elliott Lab and DCMR.

Aurora Scientific 1300A 3-in-1 Whole Animal Muscle Stimulator for Mice

Aurora Scientific 1300A 3-in-1 Whole Animal Muscle Stimulator for Mice

The 3-in1 whole animal muscle stimulator is a high performing, precise test system to test tensile and other mechanical properties of muscle.  This system combines in situ, in vivo and in vitro muscle testing using one platform to study muscle physiology in rodent (mouse) subjects.  Features include a precision force transducer for in situ tests, force transducer with plate for in vivo tests, and 25mL horizontal bath for in vitro tests.  Peak forces range from 0.5 to 10N.

BioRobotic Joint Testing System

Description: Kuka KR 160 R1570 nano robot for multi-axial biomechanical testing of musculoskeletal joints (e.g., knee, hip, spine, and others). Human joints are loaded in all six degrees of freedom (3 perpendicular forces and 3 perpendicular moments). Replication of these physiological loads and moments, and measurement of all six corresponding deformations is needed to evaluate the biomechanical function of human joints.Kuka KR 160 R1570 nano robot

Deli Slicer

A deli slicer is available for rapid rough cutting of soft tissue, which is usually cut while semi-frozen and embedded in a cellulose gel.  For tough tissues, the resulting slices are somewhat uneven in thickness, but better than using a vibratome or cutting by hand.  This is a quicker but lesser-quality alternative to the Leica SM2400 freezing stage microtome.

Leica SM2400 Sledge Microtome with freezing stage

The freezing stage allows soft tissues to be cut to precise dimensions, with parallel faces and thus uniform thickness.  The freezing stage is somewhat larger than typically available in a cryotome rotary microtome.

Meca500- R4 Robot

6 degreMeca500- R4 Robote-of-freedom testing system that can be controlled by force or position in every direction with adequate resolution to study orthopaedic tissues from small animal models like rats and mice. This will enable cutting edge mechanical testing of musculoskeletal systems from common preclinical model studies. The 6 degree-of-freedom analyses allows you to assess physiologically relevant movements like clinical exams and walking patterns.

NAC HX-7 High-Speed Camera

High-resolution and high-framerate video camera.  This camera configuration maximizes resolution at the expense of exhibiting a mid-range framerate. Generally this is the correct trade-off for tests of biological tissue.

  • 2560 × 1920 px @ 850 fps
  • 1920 × 1080 px @ 2000 fps
  • Resolution may be sacrificed further for greater framerate.
  • Macro (1× magnification) capable: 30 mm × 20 mm field of view at ~ 40 cm working distance.
  • 32 GB memory buffer

Scanning Laser Interferometer

The scanning laser interferometer measures the height profile (i.e., cross-sectional area) of a specimen without contact, which is helpful when the specimen is too soft for accurate micrometer measurements.   The specimen is placed flat on an x–y stage and the laser interferometer records a height profile as the x–y stage is traversed.
