TABLE II.
Types of mechanical strain generated with microfluidic-based stretching platforms. Cross-comparison between types of strain is often difficult. As an example, a 10% linear strain is correlated for each strain type with its associated surface strain.
| Type of mechanical strain (illustration of a stretched cell) | Type of mechanical strain | Linear strain (num. example) | Surface area strain |
|---|---|---|---|
 |
Uniaxial strain (x) | 10% | 10% |
 |
Bi-axial strain (xy) | 10% | 21% |
 |
Bi-axial strain (xz) | 10% | ≈10% |
 |
Tri-axial strain (xyz) | 10% | ≈21% |
