Polydimethylsiloxane (PDMS) micropillar-based biotransducers are extensively used in cellular force measurements. The accuracy of these devices relies on the appropriate material characterization of PDMS and modeling to convert the micropillar deformations into the corresponding forces. Cellular contraction is often accompanied by oscillatory motion, the frequency of which ranges in several hertz...
Polymeric sensor arrays have been extensively used to measure cellular forces and offer new insight into the study of cellular mechanics. Previous studies have been focused on using transducers in static domain and assumed elastic beam theory as a force conversion model. Neglecting the inherent viscoelastic behavior of Polydimethylsiloxane (PDMS) and low aspect ratios of micropillars compromised the...
