The administration of (biologically-derived) drugs for various disease conditions involves consumption of resources that constitutes a direct monetary cost to healthcare payers and providers. An often ignored cost relates to a mismatch between patients' preferences and the mode of drug administration. The "intangible" benefits of giving patients what they want in terms of the mode of drug deliv...

In this paper design of a two-axis capacitive accelerometer is described. Variation of capacitance of the device with applied acceleration as well as sensitivity of the device is analyzed. The performance analysis of the device is done using ANSYS Multyphysics software. From the analysis results, a capacitive mems accelerometer with enhanced sensitivity has been proposed. The sensitivity of the...

The subsurface wastewater infiltration system (SWIS) receives the effluent pretreated in the septic tank and purifies it through biological, physical, and chemical reactions as it passes through the unsaturated soil to the ground water. An important component of the infiltration system is the biomat, a layer of organic and inorganic material and bacteria that forms at the interface between the ...

A MEMS vibration-driven electret generator for energy harvesting has been developed. Parylene high-aspect-ratio flexible spring is employed to support the seismic mass with high-performance patterned electret. The seismic structure enables large in-plane oscillation amplitude of 1 mm and low resonant frequency of 37Hz. With our early prototype, we have obtained 21 Vp-p voltage output, correspon...

A thin film lead zirconate titanate, Pb(Zr,Ti)O3 (PZT), MEMS power generating device is developed. It is designed to resonate at specific frequencies from an external vibrational energy source, thereby creating electrical energy via the piezoelectric effect. Our cantilever device i t 2 f 1 d r ©
