This work presents passive time delay valves for micro channels in two different working modes for microfluidic on chip timing. The delay valve designs are compatible with conventional lamination techniques for microfluidics and allow to pre-program advanced sequential operations independent from the geometries of the microfluidic system. The time delay of the dissolvable valves ranges from 1.2...

A scanning thermal microscope working in passive mode is described. This tool uses a thermocouple probe and is presented as a thermal imaging system. The surface temperature distribution of a thermal micro-component is presented. We point out the capacity of our system to perform surface temperature images under conditions for which most of usual techniques cannot operate. The thermal microscop...

A priority issue within coal mines is ensuring the safety of underground personnel. It is vitally important to have upto-date information about: which districts personnel are working; if there is adequate provision of safety equipment and facilities, and whether the mine enviroment is hazardous. This paper canvasses recent developments in proximity identification and tracking techologies for mi...

The main theme is to produce novel electric and dielectric nanostructures and develop new applications in micro and nanoelectronics for these nanostructures. Scientific objectives of this project are: (1) to produce uni-axial nanostructures in polymeric thin films using high energy ion beam irradiation (2) to understand their electric and dielectric properties (3) to evaluate their application ...

We present a dielectric elastomer actuator (DEA) for in vitro analysis of mm biological samples under periodic compressive stress. Understanding how mechanical stimuli affect cell functions could lead to significant advances in diseases diagnosis and drugs development. We previously reported an array of 72 micro-DEAs on a chip to apply a periodic stretch to cells. To diversify our cell mechanot...

most of the researches do not differentiate between intuitive critic and passive one – in the field of features, applications and methods. this critical school is called emotional or passive critics which emphasizes aesthetics. thus sensitivity is not the only appliance to wisdom but is a mean to inspire happiness or unhappiness feeling. consequently the passive (critical) school is the result ...
