Motion capture camera system  (Optotrak Certus, Northern Digital Inc)

11.6.14 Optotrak motion capture system
Optotrak motion capture system

This camera system allows us to measure three-dimensional kinematics in real time.  We use this to measure joint kinematics, soft tissue strains, and relative rigid body movement (for example, implant micro-motion).

Features

  • 4m x 3m x 3.5m capture volume
  • 10 micron resolution
  • 4600 Hz acquisition frequency

Materials test machine  (Instron)

We can measure the tensile, compressive, and shear mechanical properties of biological tissues in vitro or within a biological environment chamber.

Features

  • Load measurement accuracy: +/- 0.5% of reading down to 1/1000 of load cell capacity option (2580 Series load cells)
  • Up to 2.5 kHz data acquisition rate option simultaneous on load, extension, and strain channels
  • Speed range of 0.001 – 3000 mm/min (0.00004 -120 in/min)

Dynamic pressure measurement  (TekScan)

We can measure the time and spatial varying pressure within joints or between fixtures using a flexible pressure measurement device.

Features

  • I-scan system designed for joint pressure systems
  • Pressure maps for shoulder, wrist, and knee joint

6 degree of freedom load cells  (JR3 and ATI)

We can measure the time varying forces and moments in a compact load cell and DAQ system that integrates with custom fixtures as well as the materials testing machine to allow for smaller-scale high resolution kinetic data capture.


Beckman Institute for Advanced Science and Technology

BeckmanOur lab is an affiliate member of the Beckman Institute Imaging Technology Group.

The Microscopy Suite offers a wide range of imaging modalities and supporting equipment for the preparation, imaging, and analysis of a variety of biological, materials, and biomaterials specimens.

The Vis Lab supports a variety of visualization research, including 2D and 3D image analysis and quantification, scientific visualization, ultra-high speed video, macro-photography, macro-video, video production, 3D animation, high-resolution 2D scanning, 3D object scanning, research presentation, publication graphics, and additional capabilities in support of imaging.

Materials Research Laboratory – Center for Microanalysis of Materials

mrlThrough the MRL, we have the capacity for biological materials characterization at several length scales.  Instruments of interest include:

DMA800 Dynamic Mechanical Analysis (DMA) measures a material’s Young’s modulus or viscoelastic properties as a function of temperature (or time). Testing can be performed in either tensile or cantilever bending geometries.

HYSITRON TI-950 TRIBOINDENTER The Hysitron TI 950 TriboIndenter at the Materials Research Laboratory is a versatile instrument with capabilities beyond traditional quasistatic nanoindentation. In addition to a standard transducer which can apply micronewton-to-few-mN loads over a displacement range of several micrometers, a high load transducer allows indents to be made at loads of up to 2.8 N over a displacement of up to 90 microns.

Advanced Materials Testing and Evaluation Laboratory

The Advanced Materials Testing and Evaluation Laboratory is a state-of-the-art facility for mechanical testing of coupon specimens to determine baseline engineering properties, conduct sophisticated biaxial testing, and perform full field optical stress analysis.

The lab includes test frames with a range of tension-tension and tension-torsion loading at rates appropriate for creep testing up to high cycle fatigue analysis. Each of these machines can additionally be coupled with a broad range of temperature control capabilities.

Mechanical Testing Machines

  • 10 kN uniaxial servohydraulic frames (3)
  • Mini 500 N test frame frame
  • 90 kN Creep test frames (2)
  • Ceramic compressive fatigue test fixture
  • Corrosive environment test laboratory
  • R.R. Moore Rotating fatigue machine (10,000 rpm)
