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, ...

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode embedded within the channel wall, tuning the surface charge in a region of the channel and subsequently altering ...

Dielectrophoresis (DEP) is a method for cell manipulation without physical contact in lab-on-chip devices, since it exploits the dielectric properties of cells suspended in a microfluidic sample, under the action of locally generated high-gradient electric fields. The DEP platform that has been developed offers an integrated solution for customizable applications. Several functional units, ...

Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material parameters for the physical behavior of even commonly employed design materials can be very difficult and ...

A micromirror or a torsional actuator in general has been proven to be one of the most popular actuators fabricated by Micro-Electro-Mechanical System (MEMS) technology in many industrial and biomedical applications such as RF switches, a laser scanning display, an optical switch matrix, and biomedical image systems. In this paper, two stacked micromirrors are presented and analyzed to show ...

Introduction: Accurate fluid temperature control in microfluidic channels is a requirement for many lab-on-chip and micro-reactors.Thin films resistive metal heaters have proven to be the best choice for localizing heating applications with integrated microfluidic systems. A thin platinum layer has been chosen as the metal used to realize the meander because of its positive and linear ...

In this research, we performed multiple COMSOL Multiphysics® simulations. We analyzed the dispersion curves of waves in a LAMB wave pressure sensor; simulated a thin metal film in a microbolometer and observed the resulting stress; investigated the thermal behavior of an acoustic wave microbolometer; and modeled the fluid-structure interaction (FSI) for piezoelectric-based energy harvesting from ...
