Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

Advanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Identification of weakly coupled multiphysics problems. Application to the inverse problem of electrocardiography [PDF]

Journal of Computational Physics, vol. 283, p. 271-298, 2015, 2015
This work addresses the inverse problem of electrocardiography from a new perspective, by combining electrical and mechanical measurements. Our strategy relies on the defini-tion of a model of the electromechanical contraction which is registered on ECG data but also on measured mechanical displacements of the heart tissue typically extracted from ...
