Optical Manipulation of Microscopic Objects

R. Ozawa
Yokohama University

In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.

Coupling QC, MTS-MD, and DPD with Molecular Theory of Solvation in a Framework of Multiscale Methods

[2] National Institute for Nanotechnology, Edmonton, AB, Canada

Multiscale modeling has been energetically developing in recent decades. Multiscale approximations are popular in theoretical developments, as they dramatically improve accuracy, efficiency, and applicability by self-consistently coupling models and methods at different length and time scales. This work reviews and addresses the combination of quantum chemistry methods, molecular theory of ...

The objective of this work is to develop a MEMS based Variometer to measure the vertical speed and to sense the instantaneous rate of climb or descent in Aircrafts to meet the miniaturization requirements in avionics industry. The design consists of dielectric material in between two micro electrodes. The micro diaphragm is placed on one of the electrode. As the aircraft changes altitude, the ...

Design & Finite Element Analysis of Micro Electro Mechanical Capacitive Temperature Sensors

N. Z. Khan [1],
[1] Rutgers University, New Brunswick, NJ, USA

This paper presents the design and simulation of novel micrometer-scale capacitive temperature sensors, which could serve as a component for miniaturized wireless sensor nodes for the internet of things requiring structural flexibility and optical transparency. The proposed sensor design employs a conventional, planar interdigitated capacitor structure, explores the thermo-mechanical property ...

Investigating the Use of a Piezoelectric Actuator for the Appendages of a Microrobot

J. Clark, and J. Clark
Purdue University, West Lafayette, IN, USA

We investigate the use of a piezoelectric actuator for the appendages of a microrobot. Possible uses may include micro assembly, mobile surveillance, etc. What is different about this microrobot is that it uses 2 degrees of freedom, low powered piezoelectric flexures, while attempting to mimic the maneuverability of an ant-like insect. In the paper, we use COMSOL to characterize this type of ...
