Identify the opportunity for an assistive device

Investigate the biomechanical requirement of your target activity. Simulate your target users performing the activities. Compute individual muscle forces and metabolism along with joint contact-forces and moments. Compare the biomechanical requirement of your target task with a baseline (such as ergonomic standards). Identify criticalities that could be supported by a wearable assistive device, robot, or both passive- and active exoskeleton. Quantify the need of an assistive device and estimate the required assistance. See also AnyBody for Ergonomics

Examples of modeling and simulation of assistive devices

  • Augment laboratory and field studies with biomechanical analyses.
  • Use simulation studies as in-silico evidence of the efficacy and safety of your device.
  • Supplement functional and safety portfolio of your device with simulations studies.
  • Test your assistive device’s fit and support through population-based simulations.
  • Investigate how different mechanical design parameters can affect the user.
  • Evaluate changes in the internal body loads (e.g., muscle activities, joint reaction forces, compression forces etc.)
  • Simulation-based design of exoskeletons using musculoskeletal analysis
  • Modeling and simulation of a lower extremity exoskeleton
  • Modeling and simulation of an upper extremity exoskeleton
  • Simulation-based design of exoskeletons using musculoskeletal analysis
