Frequency dependent viscoelastic properties of porcine bladder

Research output: Contribution to journalArticlepeer-review

Abstract

The aim of this study was to measure the viscoelastic properties of bladder tissue. Porcine bladders were dissected into rectangular strips and loops. Dynamic Mechanical Analysis was used to measure the viscoelastic properties of the bladder tissue (storage and loss stiffness) tested in a frequency range of up to 10Hz. Storage stiffness was found to be consistently higher than loss stiffness. Average storage stiffness was found to be 1.89N/mm and 0.74N/mm for looped and rectangular samples, respectively. Average loss stiffness was found to be 0.24N/mm and 0.11N/mm for looped and rectangular samples, respectively. The results of this study are important for computational modelling of the bladder and for ensuring that engineered bladder tissues have physiological viscoelastic properties.
