The growth of the chemical industry has brought tremendous challenges to sensing technology. Chemical sensors based on metamaterials have great potential because their label-free and non-destructive characteristics. However, applied in mainly been investigated from measurement sample concentration or determination dielectric properties at a fixed frequency. Here we present metamaterial integrated microfluidic (MIM) sensor for multi-band property chemicals, which is promising identification...
Abstract Wearable biomechanical energy harvesting devices have received a lot of attention recently, benefiting from the rapid advancement theories and in field micro electromechanical system (MEMS). They not only fulfil requirements for powering wearable electronic but also provide an attractive prospect self-powered flexible when wearing. In this article, we review technology applications. Three different forms mechanisms, including piezoelectric effect, electromagnetic electrostatic are...
Air damping significantly influences the dynamical characteristics of MEMS accelerometers. Its effects at micro-scale level sharply depend on structure layouts and size devices. The phenomenon comb microaccelerometers is investigated. air between fixed plate electrodes movable cannot flow freely compressed. damping, therefore, exhibits both viscous stiffness effects. former generates a drag force like that in macromechanical systems, proportional to velocity electrodes. latter stiffens...

Specifically, SSAW generated by two parallel interdigital...
Further investigation of theoretical models is essential to physically understand triboelectric nanogenerators (TENGs) and then promote their extensive applications. Theoretical approaches in the existing studies mainly focus on establishing equivalent circuits, which provide a rapid analysis method but with relatively low precision. Therefore, we propose field-view model theoretically analyze physical mechanism TENGs, reveals high efficiency great accuracy. After comprehensive study, it...
