OnDemand Webinar Series

Hardness Testing of Soft Biomaterials and Hydrogels through Indentation Analysis

Mar 30, 2021 12:00pm ‐ Mar 30, 2021 1:00pm



Soft materials represent a large portion of biomedical and bioengineering research. Until recently, the mechanical properties of soft tissues and hydrogels have not truly been studied. However, given recent developments of new scaffolds and more localized medical treatments, understanding the mechanical properties of soft biomaterials is becoming critical.

This webinar will elucidate the nanoindentation approach for the measurement of soft materials that will be demonstrated via several topics and pertinent real-world examples including:

  • Why indent soft materials
  • Cartilage: stiffness gradient of human knee cartilage
  • Cornea: how stiff is human cornea and how can indentation help in treatment of corneal conditions
  • Contact lenses: effect of loading rate on elastic modulus—tunable comfort
  • Hydrogels: solid, liquid, or gel
  • Hyaluronic acid foils: properties of thin hydrogel sheets

An interactive Q&A session follows the presentation.
