Strengths & Limitations

Strengths

  • +Innovative biomimetic approach.
  • +Demonstrated high performance metrics (acuity).
  • +Utilized advanced manufacturing (3D printing).

Limitations

The complexity of the 3D printing process and the specific materials used might be difficult to replicate without access to specialized equipment.
