Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A computational model of a SWCNT device was developed using COMSOL Multiphysics to investigate the complete electrical ...

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high-doped constriction region, and the high-doped leg region) is solved using the general heat transfer module for DC ...

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics device can potentially be used as a source of energy. This generators have the advantage of: being silent, compact, ...

The attempt has taken to miniaturized size of non contact temperature sensor by using ultrasonic trans-receiver. The piezoelectric material is used in both transmitter and receiver ends for this ultrasonic Micro-Electronics Mechanical Systems (MEMS) based temperature sensing device. Prior to fabrication of ultrasonic MEMS device, design and simulation are extensively used to avoid wastage of ...

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is therefore zero. The theoretical idea will be tested experimentally. Here, additional effects originating from ...

In this work, electrothermal microgrippers designed using topology optimization are modeled. The microgrippers are composed of two 5 μm-thick polysilicon actuators facing each other. The gap between the actuators are 2 μm in the initial state and the microgrippers are able to both fully close and further open this gap. The operation principle of the actuators is quite similar to that of a ...

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero-dimensional (0D) structures have seen wide-ranging applications in laser diodes, solar cells and LEDs to name ...

The objective of this paper is to show the simulation of a piezoelectric thin film device and its application as a sensor. Piezoelectric aluminum nitride thin film clamped at two ends is simulated using COMSOL Multiphysics software. The device consists of the piezoelectric thin film suspended on a cavity etched on a silicon substrate. Two metal electrodes are placed at the two fixed sides of the ...

This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via COMSOL. Mode shapes and frequencies are found as functions of geometric parameters, and the results used ...
