Bilayer Stiffness Identification of Soft Tissues by Suction

Article dans une revue avec comité de lecture

CONNESSON, Nathanael; BRIOT, Noémie; ROHAN, Pierre-Yves; BARRAUD, Pierre Alain; ELAHI, Seyed Ali; PAYAN, Yohan (Springer (for Society for Experimental Mechanics), 2023-03)

Background In vivo mechanical characterisation of biological soft tissue is challenging, even under moderate quasi-static loading. Clinical application of suction-based methods is hindered by usual assumptions of tissues ...
In vivo quantification of 3D displacement in sacral soft tissues under compression: Relevance of 2D US-based measurements for pressure ulcer risk assessment

Article dans une revue avec comité de lecture

MUKHINA, Ekaterina; TREBBI, Alessio; ROHAN, Pierre-Yves; CONNESSON, Nathanael; PAYAN, Yohan (Elsevier, 2022-09)

Objective 2D Ultrasound (US) imaging has been recently investigated as a more accessible alternative to 3D Magnetic Resonance Imaging (MRI) for the estimation of soft issue motion under external mechanical loading. In ...
Non-operable glioblastoma: Proposition of patient-specific forecasting by image-informed poromechanical model

Article dans une revue avec comité de lecture

URCUN, Stéphane; BAROLI, Davide; ROHAN, Pierre-Yves; SKALLI, Wafa; LUBRANO, Vincent; BORDAS, Stéphane Pierre Alain; SCIUME, Giuseppe (Elsevier BV, 2023-03)

We propose a novel image-informed glioblastoma mathematical model within a reactive multiphase poromechanical framework. Poromechanics offers to model in a coupled manner the interplay between tissue deformation and ...
Single and bi-compartment poro-elastic model of perfused biological soft tissues: FEniCSx implementation and tutorial

Article dans une revue avec comité de lecture

LAVIGNE, Thomas; URCUN, Stéphane; ROHAN, Pierre-Yves; SCIUME, Giuseppe; BAROLI, Davide; BORDAS, Stéphane Pierre Alain (Elsevier, 2023-05)

Soft biological tissues demonstrate strong time-dependent and strain-rate mechanical behavior, arising from their intrinsic visco-elasticity and fluid–solid interactions. The time-dependent mechanical properties of soft ...
In vivo mechanical response of thigh soft tissues under compression: a two-layer model allows an improved representation of the local tissue kinematics

Article dans une revue avec comité de lecture

SEGAIN, Alexandre; SCIUME, Giuseppe; PILLET, Helene; ROHAN, Pierre-Yves (Elsevier BV, 2024-05)

Biomechanical parameters have the potential to be used as physical markers for prevention and diagnosis. Finite Element Analysis (FEA) is a widely used tool to evaluate these parameters in vivo. However, the development ...
Forward to the special issue on biomechanics of breast tissues and its clinical applications

Article dans une revue avec comité de lecture

ROHAN, Pierre-Yves; PAYAN, Yohan (Elsevier BV, 2024-02)

Biomechanical modelling of human breast tissue has been studied for the past 20 years for various medical applications, including surgical training, preoperative planning, diagnosis and clinical biopsy, mammography, ...
Flip-chip technology at room temperature: A new design of microtube-based interconnect for improved mechanical and electrical properties

Article dans une revue avec comité de lecture

DESBORDES, Cloé; PESCI, Raphaël; PIOTROWSKI, Boris; MAILLIART, Olivier; RAPHOZ, Natacha (Elsevier BV, 2024-10)

Flip-chip assembly of photonic components can be achieved at room temperature by using 10 μm pitch interconnects made of metallised oxide microtubes inserted into ductile reception pads. In order to reduce the electrical ...
