Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...

High-precision and high-purity acquisition of tumor cells from whole blood is vital for early disease detection diagnosis. Here, we investigated a cascaded inertial acoustic microfluidic device sheathless label-free separation circulating (CTCs) the through numerical methods. We introduced spiral microfluidics channel in first stage (1st) cell focusing rough sorting to improve chip integration ...

Electroosmosis is one of the most used actuation mechanisms for microfluidics in current active lab-on-chip devices. It generated on induced charged microchannel walls contact with an electrolyte solution. Electrode distribution plays key role providing external electric field electroosmosis, and determines performance electroosmotic microfluidics. Therefore, this paper proposes a topology opti...

Microfluidics is a hot topic and one we have previously written about in this column. We have covered everything from microchips to rethinking the glucometer. Recently, we rediscovered a 2011 report (1 ) that takes the ideas behind microfluidics—manually or passively manipulating a fluid, particularly to identify what is in it—and suggests applying new knowledge we have about the ever-familiar ...

Digital microfluidics (DMF) is a popular alternative to traditional in-channel microfluidics, which allows precise control of individual droplets. Most commonly used droplet manipulation methods for DMF are electrowetting on dielectric (EWOD) and magnetic actuation. Both methods require high surface hydrophobicity to facilitate droplet movement, and often superhydrophobic surfaces are used to f...

This study focuses on the fabrication and characterization of Love wave surface acoustic wave (LW-SAW) sensors with a thin nano-crystalline diamond (NCD) coating with an integrated microfluidics system. The effect of diamond layer thickness on the acoustic wave phase velocity and the sensor’s sensitivity have been investigated experimentally and compared with theoretical simulations. The fabric...

The capacity to produce therapeutically relevant quantities of multipotent mesenchymal stromal cells (MSCs) via in vitro culture is a common prerequisite for stem cell-based therapies. Although culture expanded MSCs are widely studied and considered for therapeutic applications, it has remained challenging to identify a unique set of characteristics that enables robust identification and isolat...

Driven by its importance in nature and technology, droplet impact on solid surfaces has been studied for decades. To date, research on control of droplet impact outcome has focused on optimizing pre-impact parameters, e.g., droplet size and velocity. Here we follow a different, post-impact, surface engineering approach yielding controlled vectoring and morphing of droplets during and after impa...
