... are needed to assist tissue engineering researchers as they embark on this process. The necessary multidisciplinary expertise covering micromechanical design, mechatronics, viscoelasticity, tissue culture, and human ergonomics is not necessarily available to all research teams. Therefore, the challenge...

Linovitz; James Kuras; Kari Zimmers A viscoelastic artificial disc may more closely replicate normal stiffness characteristics of the healthy human disc compared with first-generation total disc replacement (TDR) devices, which do...

... force display were only able to maintain a constant force with 20 times worse variation than the automatic controller. The system was also used to determine the viscoelastic properties of soft tissues. 12 08 2010 actuators biomechanics biomedical equipment biomedical ultrasonics...

.... Magnetic resonance (MR) elastography is a promising noninvasive method to quantitatively measure the viscoelastic properties of biological tissue. We developed a new quasi-static actuation system with the spatial modulation of magnetization (SPAMM) imaging pulse sequence. The MR compatible actuation system...

... such that existing equipment is not optimized for the necessary range of forces and displacements. In this paper, we describe a new device for determining viscoelastic material properties of small biologic specimens and show early results from its use. The mechanical design, control system, and theoretical...

... and frequency of mechanical load applied to the rabbit’s hind limb for various durations. The measurement of tissue compliance and the viscoelastic properties as a function of loading parameters was also demonstrated. Findings of this study suggest that this device offers a quantitative analysis of the applied...

...Eric Fahlgren; Mark Carlson; Andrew S. Elliott Advanced design of human artificial joints requires an in-depth understanding of the dynamic interaction between the very stiff bone replacement material and the softer viscoelastic cartilage replacement material. It must take into account both...
