Low back pain is a major physical and socioeconomic problem. A significant percentage is attributable to internal disc disruption (IDD). The management of IDD has been limited to conservative treatment or to operative treatment. Intradiscal electrothermal therapy (IDET) is a new minimal-invasive therapy. In carefully selected patients, it could be an effective treatment alternative. Further stu...

in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

Smart e-textiles, which are capable of wireless transmission, signal conversion and energy transduction, have the capability to provide added values be more versatile. However, there still many challenges in fabricating a flexible durable smart fabric with high-level multifunctional integration. Herein, novel two-dimensional (2D) material, Ti3C2Tx MXene, zero-dimensional (0D) silver nanoparticl...

The aim of the project COUPLET (supported by Institut Farman) is to study the electrothermal effects of the degradation of the metallisation layer of power semiconductor dies. In this first technical report of the project, we describe our work of modeling and simulation of the behavior of a power transistor. The die is represented by four elementary transistors driven by a distributed gate sign...

We study a recently demonstrated AC electrokinetic technique for manipulation and concentration of colloidal particles on an electrode surface. The technique uses indium tin oxide (ITO)-based parallel-plate electrodes on which highly localized infrared (1064 nm) laser illumination is shone. We show that the highly localized laser illumination leads to a highly nonuniform heating of the electrod...

Internal disc disruption is a common cause of disabling low back pain in a substantial number of young, healthy adults. A clinical diagnosis of internal disruption, in absence of objective clinical findings, is convincingly established only by means of provocation discography. Intradiscal electrothermal therapy has been shown to be effective in managing chronic disabling discogenic pain. This p...

This paper addresses the experimental identification of a servo actuator which is used in many industrial applications. Because the system consisted of electrical and mechanical components, the behavior of the system was nonlinear. In addition, the under load behavior of this servo was different. The load torque was considered as the input and a two input-one output model was presented for t...

In this work, we focus on investigating electrothermal flow in rotating electric fields (ROT-ETF), with primary attention paid to the horizontal traveling-wave electrothermal (TWET) vortex induced at the center of the electric field. The frequency-dependent flow profiles in the microdevice are analyzed using different heat transfer models. Accordingly, we address in particular the importance of...

Capture and recovery of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from gas streams using physical adsorption onto activated carbon fiber cloth (ACFC) is demonstrated on the bench-scale. This system is regenerated electrothermally, by passing an electric current directly through the ACFC. The adsorbate desorbs from the ACFC, rapidly condenses on the inside walls of th...
