Thermoelectric (TE) devices generate electrical potential when they have temperature difference. Silicon is one of the materials applied to TE devices. However, most of the studies about TE silicon devices have focused on 1D structure, like Si nanowire, not on 2D. In this study, silicon ... 詳細を見る

Of utmost importance in appliance design and manufacture are the features for protection from fire and for personal safety. Appliance engineers are continually in pursuit of better,longer-life appliances that will provide both lower cost to the consumer and lower energy consumption. ... 詳細を見る

As a key component of MEMS, microprocessor with high computing performances is facing with severe thermal challenge due to the increasing power density, miniaturization as well as higher operating temperature requirements, and thermal management in corresponding fields has become one of ... 詳細を見る

The spindle is regarded as the heart of the CNC machine tool. Typically, the spindle is operated using the belt or gear drives to realize the relative motion between workpiece and cutting tool. However, they cannot be operated at high speeds due to power transmission losses, thus ... 詳細を見る

The growth of the electronics industry demand better components for the electronic systems. Such components need to be improve to keep up with the evolution of the digital era. The loudspeaker design has not been changed for almost a century [1-5]. The acoustic transducer is the last ... 詳細を見る

Electrochemical machining (ECM) is a manufacturing technology that allows metal to be precisely removed by electrochemical oxidation and dissolution into an electrolyte solution. ECM is suited for machining parts fabricated from “difficult to cut” materials and/or parts with complicated ... 詳細を見る

In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the ... 詳細を見る

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... 詳細を見る

Surface acoustic wave (SAW) devices are commonly used as wireless filters, resonators, and sensors. The confinement of acoustic energy near the surface of a piezoelectric substrate in a SAW sensor makes it highly sensitive for discerning surface perturbation. As sensors, SAW devices have ... 詳細を見る

Soil’s electromagnetic properties adversely affect the performance of electromagnetic induction (EMI) sensors and if conditions are severe enough, render them useless. A simple circuit model is often used to express the electromagnetic induction response of a target analytically. This ... 詳細を見る
