Biomechanical properties

Definition

Biomechanical properties refer to the physical characteristics of biological tissues that dictate how they respond to mechanical forces. These properties, such as elasticity, strength, and viscosity, are crucial in understanding how tissues behave under stress and strain, which is particularly important for designing effective bioreactors that can mimic the natural environment for tissue engineering applications.
