Acousto-Mechanical Instrumentation of Multiscale Hysteretic Memristive Properties of the Skin with Nonlinear Time Reversal Imaging

Abstract

The aim of this paper is to present an acousto-mechanical based experiment for skin ageing characterization using the Nonlinear Time Reversal signal processing tool known to extract, in a complex medium, sources of multiscale non-linearity potentially responsible of skin ageing process. New biomarkers of the porcine skin ageing are identified thanks to an optimized mixture of Preisach-Mayergoyz distributions extracted experimentally. Then each hysteretic elementary unit is supposed to be identified with a electronic memristor with suitable memory resistance controlled electronically.
