This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... En savoir plus

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... En savoir plus

The aim of this work is to investigate the impact of the structural parameter on the signal of the impedance based microfluidic flow cytometer for cell detection. A well-established optical technique for counting, identifying and sorting cells is flow cyto-fluorimetry, which is an ... En savoir plus

 Measuring soil moisture content plays an important role not only for sustaining dry farming but also for soil mapping. Our work includes developing a soil moisture sensor which is based on the principle of the Dual-Probe Heat-Pulse method to measure soil moisture content. To validate ... En savoir plus

Volatile Organic Compounds (VOC) are a wide range of carbon based organic chemical compounds which evaporate easily at room temperature referred as volatile in nature. Human exhaled breathe consists of carbon dioxide (CO2) along with more than 3000 Volatile Organic Compounds exists like ... En savoir plus

Rebar detectors are used extensively by construction contractors to locate rebars while drilling, coring or cutting in RCC to avoid causing damage to the reinforcement steel. These detectors are also used by inspection engineers for spot checking of civil infrastructure. Most cost ... En savoir plus

Numerical investigations of magnetorheological elastomer millimeter-scale robots capable of undulatory swimming under magnetic body torques are realized for the first time in low Reynolds number condition using AC/DC, CFD, Structural Mechanics modules in COMSOL Multiphysics®.
