What is Biomedical Engineering?
3
Areas of Expertise
  • Tissue Mechanics (engineering)
  • Mechanical, Engineering Mechanics, Chemical, and
    Biomolecular
  • Medical Devices (surgical or otherwise)
  • Mechanical, Engineering Mechanics, Industrial
  • Biomechanics/Rehabilitation
  • Mechanical, Engineering Mechanics, Industrial
  • Image Analysis/Pattern Recognition
  • Computer Science and Engineering

4
Mechanical Devices
5
Tissue Mechanics and New Ideas
  • Tissue Mechanics
  • Obtain mechanical properties
  • Concerned with shear behavior, not just axial
    stress-strain
  • Developing a very small measurement fixture

UNL Carl Nelson UNMC J. Hammel
Test Set-up
  • Make surgery easier, more effective, and more
    accessible
  • Tool tracking in minimally invasive surgery
  • Modular surgical robots
  • Custom tools for tasks that are repetitive and
    mechanically difficult/time consuming

6
Miniature In Vivo Robots for Surgery
  • Better
  • Miniaturized robots function entirely within the
    body
  • Access to more surgical sites and organs
  • Improved visualization
  • Reduced incisions
  • Faster
  • Limited set-up time
  • Additional tools can be added or removed quickly
  • Cheaper
  • Mass produced
  • Nor hardware infrastructure (laptop enabled)
  • Disposable

Nano Touch Sensors Ravi Saraf, Chemical
Engineering, rsaraf_at_unl.edu
Resolution is 20 mm which is 2-fold smaller than
human finger and 100 fold smaller than the
current Electronic MEMS devices.
Disphering cancer by texture The surgeon has a
resolution of our sensor is 20 mm. Giving
surgeon the sensation of human touch during
minimally invasive procedure

Single Electron Nanodevice to Measure
Electrochemical Activity in a Single Cell Ravi
Saraf, Chemical Engineering, rsaraf_at_unl.edu
  • Combinatorial microarray with low false positive
    Using the necklace as nano-electrode and
    combining with our combinatorial electrochemistry
    device, will allow us to measure perform
    microarray analysis using cells as the
    transduction agency.
  • Live Bio-transistor Use cell as a gating device
    to make electronics that is intelligent and
    adaptable.
  • Power generation Use the charge production form
    the cell (such as ATP cycle) to convert food
    directly to electricity.
