The emerging technologies on mobile-based diagnosis and bioanalytical detection have enabled powerful laboratory assays such as enzyme-linked immunosorbent assay (ELISA) to be conducted in field-use lab-on-a-chip devices. In this paper, we present a low-cost universal serial bus (USB)-interfaced mobile platform to perform microfluidic ELISA operations in(More)
This paper presented a novel droplet-based pressure sensor using elastic and capacitive electrode-electrolyte interfaces to achieve ultrahigh mechanical-to-electrical sensitivity (1.58 μF kPa(-1)) and resolution (1.8 Pa) with a simple device architecture. The miniature transparent droplet sensors, fabricated by one-step laser micromachining, consisted of(More)
Droplet-based transport phenomena driven by surface tension have been explored as an automated pumping source for a number of chemical and biological applications. In this paper, we present a comprehensive theoretical and experimental investigation of unconventional droplet-based motions on a superhydrophobic-patterned surface microfluidic (S(2)M) platform.(More)
In recent years, micropatterning techniques have gained increasing popularity from a broad range of engineering and biology communities for the promise to establish highly quantitative investigations on miniature biological objects (e.g., cells and bacteria) with spatially defined microenvironments. However, majority of the existing techniques rely on(More)
Textile-enabled interfacial microfluidics, utilizing fibrous hydrophilic yarns (e.g., cotton) to guide biological reagent flows, has been extended to various biochemical analyses recently. The restricted capillary-driving mechanism, however, persists as a major challenge for continuous and facilitated biofluidic transport. In this paper, we have first(More)
Variable-speed constant-frequency (VSCF), a new typed operational mode for the doubly fed induction generator based wind power generation system is proposed based on the grid-connected power transmission. A control method aimed at increasing efficiency and maximizing energy capture using the stator flux-orientation control technology is introduced. The(More)
The eukaryotic cytoplasm contains a variety of ribonucleoprotein (RNP) granules in addition to the better-understood membrane-bound organelles. These granules form in response to specific stress conditions and contain a number of signaling molecules important for the control of cell growth and survival. However, relatively little is known about the(More)
With the launch and rapid development of a novel satellite WorldView-2, study on fusion of panchromatic and multispectral images from the satellite has become a hot spot. As there are generally a pair of contradictions existing in the panchromatic and multispectral image fusion method: either failure to avoid spectral distortion, or need of introducing a(More)
To resolve the algorithm evaluation issue of multi-sensor image fusion, we propose a novel synthetic evaluation method using multi-hierarchical gray relational analysis mechanism, which has the merit of using small-sized samples and of allowing unitary comparison. The proposed method combines a priori knowledge and quantization evaluation. In this paper we(More)
