In this paper, methods of measuring the softness of open-cell polyurethane foams in terms of their Young's modulus using indentation methods are investigated and shown to be in agreement with values determined by normal compression tests. The comparison involved the use of a formula relating Young's modulus for elastomers to the axial indentation forces on a cylindrical probe. This had been developed for cartilage and verified for other biological tissues and could not automatically be assumed… Expand
Evaluation of bone-tendon junction healing using water jet ultrasound indentation method.
TLDR
The results suggested that the noncontact ultrasound water jet indentation system provided a nondestructive way to evaluate the material properties of small animal tissues in situ and thus had the ability to evaluation the healing process of BTJ. Expand
A skeleton-and-bubble model of elastic open-cell foams for finite element analysis at large deformations
We formulate a new unit-cell model of elastic open-cell foams. In this model, the conventional skeleton of open-cell foams is supplemented by fitting a thin-walled bubble within each cavity of theExpand
Configurational phases in elastic foams under lengthscale-free punching
Abstract We carry out experiments with brick-like specimens of elastic open-cell (EOC) foams of three relative densities. Individual specimens may be “tall” (height = width = depth) or “short” ( 2Expand
Probing model tumor interfacial properties using piezoelectric cantilevers.
TLDR
The shear modulus (G) to elasticModulus (E) ratio, G/E, is examined as a quantity to describe model tumor interfacial roughness using a piezoelectric cantilever capable of measuring both tissue elastic modulus and tissue shearmodulus. Expand
Skin stiffness determined from occlusion of a horizontally running microvessel in response to skin surface pressure: a finite element study of sacral pressure ulcers
TLDR
The study indicates that the critical value of the SSP for microvascular occlusion is determined not only by the stiffness of homogenized skin with microvasculature but also by the intraluminal pressure, microv vascular wall stiffness, and body support conditions. Expand
MEMS Endoscopic Tactile Sensor: Toward In-Situ and In-Vivo Tissue Softness Characterization
TLDR
This research aimed at restoring tactile sensing capabilities by developing a microelectromechanical systems (MEMS) tactile sensor for integration with existing MIS graspers, able to measure force, force position and also the softness of the grasped object. Expand
Hyperelastic modelling and parametric study of soft tissue embedded lump for MIS applications
TLDR
The existing MIS instruments have caused severe restrictions to surgeons' tactile perception, so the effect of an anatomical feature in general and a lump in particular on the stress distribution on the sensitive surfaces of the smart MIS graspers still needs a lot of attention. Expand
A single-use haptic palpation probe for locating subcutaneous blood vessels in robot-assisted minimally invasive surgery
TLDR
A novel low-cost palpation probe for Robot assisted Minimally Invasive Surgery (RMIS) for localizing subcutaneous blood vessels and measures probe tip deflection using a Hall Effect sensor as the spherical tip is moved tangentially across a surface under automated control. Expand
Photogrammetric prediction of girdle pressure
A new method is proposed for indirect prediction of skin pressure induced by a tight-fit girdle, using in situ photogrammetric measurements in a close range. The 3D information of the markings onExpand
Relative hardness measurement of soft objects by a new fiber optic sensor
TLDR
Experimental results verify the ability of the proposed optical sensor to measure the relative hardness of elastomeric samples, which is required to apply a small force/deformation to the object by a tactile sensor. Expand
