Hairy‐Skin‐Adaptive Viscoelastic Dry Electrodes for Long‐Term Electrophysiological Monitoring

Advanced Materials, 2023
AbstractLong‐term epidermal electrophysiological (EP) monitoring is crucial for disease diagnosis and human–machine synergy. The human skin is covered with hair that grows at an average rate of 0.3 mm per day. This impedes a stable contact between the skin and dry epidermal electrodes, resulting in motion artifacts during ultralong‐term EP monitoring ...

Interaction between long term viscoelastic and mechanosorptive response of wood

open access: yes, 2011
Since the first-published work in the 50's the time dependent behaviour raised an increasing interest in wood material research. Creep research has a decisive influence in timber structures where prediction of total deflection is necessary for durable structural design. The nature of polymeric constituents induces viscoelastic behavior to wood.

Asymptotic behaviors of solutions for viscoelastic wave equation with space–time dependent damping term

open access: yesJournal of Mathematical Analysis and Applications, 2012
In this paper, we consider a viscoelastic wave equation with an absorbing term and space–time dependent damping term. Based on the weighted energy method, and by assuming that the kernel decaying exponentially, we obtain the L2 decay rates of the ...

Multidimensional viscoelasticity equations with nonlinear damping and source terms

Nonlinear Analysis: Theory, Methods & Applications, 2004
The authors investigate the initial-boundary value problem \(u_{tt}-\Delta u_t-\sum_{i=1}^N\frac \partial{\partial x_i}\sigma_i(u_{x_i})+f(u_t)=g(u)\), \(x\in \Omega\), \(t>0,\) \(u(x,0)=u_0(x)\), \(u_t(x,0)=u_1(x)\), \(x\in \Omega\); \(u(x,t)=0\), \(x\in \partial\Omega\), \(t\geq 0,\) where \(\Omega\subset \mathbb R^N\) is a bounded domain.
