Deep Brain Stimulation (DBS) is a therapeutic tool used for a number of neurological disorders including chronic pain, incontinence and movement disorders, such as Parkinson’s disease. DBS consists of the low-frequency stimulation of an area of the brain, known as basal ganglia. The stimulation is provided by clinical implant, consisting of a pulse generator and an electrode lead ...

Micro hot embossing on a large area polymeric substrates using roll-to-roll (R2R) mode has been considered as one of the most promising technologies that can offer continuous fabrication of large area polymeric substrates. Besides continuous operation, roll-to-roll (R2R) process offers advantages such as low forming load and higher replication accuracy. Consequently, R2R embossed polymeric ...

With the rising predominance of diabetes, successful management of blood glucose levels is increasingly important. Key efforts have focused on the development of optical microscale glucose sensing systems based on the encapsulation of glucose oxidase within microspheres coated with polyelectrolyte multilayer nanofilms. A two-substrate mathematical model of microscale optical glucose sensors in ...

We present a mechanical model a growing spherical shell suitable for predicting the evolution of a Saccular Cerebral Artery Aneurysms (SCAA). It relies basically on the Kröner-Lee decomposition, used to describe the interplay between the current and the relaxed configuration of body elements. Rupture or stabilization of a SCAA are the end effect of a number of biological mechanisms, still poorly ...

One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

Modeling of 2-5 μm thin membranes into a cochlea with a width of 2 cm is computationally. The paper is focused on two approximative methods used to overcome this problem and in addition a simple model challenging of a plate capacitor with a thin membrane of different thickness in-between is presented. The results of simulations with both thin layer approximation methods are compared with ...

This paper will discuss the comprehensive solution adopted for converting the 3D digital/medical images directly into the computational model. The workflow using Simpleware Software – ScanIP and + ScanFE – will be illustrated including the option for directly exporting fully compatible models to COMSOL Multiphysics. The extra functionality that allows introduction, positioning and ...

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL Multiphysics®, we applied the 1) Michaelis Menten equation; 2) Nernst potential equation; 3) Navier Strokes velocity, ...

Worldwide, the leading cause of mortality in children is acute respiratory infection, primarily associated with pneumonia. One of the essential tools used to treat life-threatening hypoxemia due to pneumonia is the appropriate use of supplemental oxygen. While oxygen therapy is essential for many aspects of case management in hospitals and large clinics, many such health facilities have no ...

Daily application of a low intensity pulsed ultrasound (LIPUS) regimen has been shown to have positive effects on bone fracture healing. Although LIPUS treatment can induce cellular responses supporting bone repair, the underlying mechanisms are not well understood. Further in vitro experiments are needed to investigate the bioeffects of the US pulsed protocol under well-controlled conditions in ...
