Disease-causing pathogens continue presenting enormous global health problems, especially due to their easy transmittance to people via water supply systems. The detection, filtration, and purification of bacteria-contaminated water samples are complex activities, ones subject to considerable error. Here we present a new and highly effective micro-fluidic system with carbon nanotube (CNT) clust...

Flexible strain sensors with high sensitivity, wide sensing range, and excellent long-term stability are highly anticipated due to their promising potential in user-friendly electronic skins, interactive wearable systems, robotics. Fortunately, there have been more flexible materials developed during the past few decades, some important milestones reached. Among various approaches, liquid-type ...

A fluidic one-bit half-adder is made of five channels which intersect at a junction. Two channels are inputs, two channels are outputs and one channel is the drain. The channels direct fluid from input fragments to output fragments and the streams of fluid interact at the junctions. Binary signals are represented by water droplets introduced in the input channels: presence of a droplet in an in...

By introducing Colpitts oscillator as a chaotic system, this paper deals with back-stepping control method and investigates the restrictions and problems of the controller where non-existence of a suitable response in the presence of uncertainty is the most important problem to note. In this paper, the back-stepping sliding mode method is introduced as a robust method for controlling nonlinear ...

In this study, we developed a microdevice concept for drug/fluidic transport taking an inspiration from supramolecular motor found in biological cells. Specifically, idealized multi-functional design geometry (nozzle/diffuser/nozzle) was developed for (i) fluidic/particle transport; (ii) particle separation; and (iii) droplet generation. Several design simulations were conducted to demonstrate ...

A system has been developed that allows for optical and fluidic manipulation of gametes. The optical manipulation is performed by using a single-point gradient trap with a 40× oil immersion PH3 1.3 NA objective on a Zeiss inverted microscope. The fluidic manipulation is performed by using a custom microfluidic chamber designed to fit into the short working distance between the condenser and obj...

In this paper a wearable electronic-free micro-fluidic device for the continuous monitoring of pH in sweat during exercise is described. The sensing capability is based on ionogels, ionic liquid hydrogels, containing pH sensitive dyes capable of reporting pH activity in the range from 3 to 10. Previously, we reported a flexible micro-fluidic barcode capable of measuring the pH of sweat in real ...

The design, fabrication and preliminary performance assessment of a new vapor sensor comprising a microfabricated optofluidic ring resonator (μOFRR) and its application to microscale gas chromatographic (μGC) detection of volatile organic compounds (VOC) are presented. The μOFRR combines vapor sensing and fluidic transport functions in a micro-fabricated whispering gallery mode (WGM) resonator....

The content of this paper describes the model and control of a elastic joint driven by fluidic muscles including the nonlinear behavior of the fluidic muscle, the valves and the joint dynamics. Such elastic joints have a lot advantages like passive compliance, low power to weight relation. The control of the joint is developed with the help of a professional software tool named EICASLAB which h...
