Jie Wu Shailendra Dubhashi Gary H. Bernstein University of Notre Dame Department of Electrical Engineering Notre Dame, Indiana 46556 Abstract. Inductive links are widely used for implanted biomedical applications, and with amplitude modulation their use can be expanded to the transmission of pulse trains for deep brain stimulation (DBS). Using a passive envelope detector and an integrated coil,...

This paper reports on the use of bent-beam electrothermal actuators for the purpose of generating rotary and long-throw rectilinear displacements. The rotary displacements are achieved by orthogonally arranged pairs of cascaded actuators that are used to rotate a gear. Devices were fabricated using electroplated Ni, p Si, and polysilicon as structural materials. Displacements of 20–30 m with lo...

This paper presents a warpage analysis method that predicts the warpage behavior of electroplated Cu films on glass fiber-reinforced polymer (GFRP) packaging substrates. The analysis method is performed using the following sequence: fabricate specimens for scanning 3D contours, transform 3D data into curvatures, compute the built-in stress of the film using a stress-curvature analytic model, an...

the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...

This paper describes the applicability of a Hg-electroplated-Pt ultramicroelectrode in the quantification of elemental sulphur in naphtha samples by square-wave voltammetry. A reproducible deposition methodology was studied and is reported in this paper. This methodology is innovative and relies on the quality of the mercury stock solution to obtain reproducible surfaces required for the analyt...

Electro deposition of NiFeWS thin films was carried out from Tri Potassium citrate bath at a constant current density (1 A/dm) and controlled pH of 8 by varying bath temperature. Physical properties such as surface morphology, microstructure and magnetic properties such as coercivity, saturation magnetization, magnetic flux density were investigated for electrodeposited NiFeWS soft magnetic thi...

In Part I we reported experimental results obtained from isothermal stress relaxation tests of electroplated Cu thin films with and without a passivation layer and deduced grain-boundary and interface diffusivities based on a kinetic model. Here in Part II we describe the detail of the model, which is based on coupling of grain-boundary diffusion with surface diffusion for unpassivated films an...
