Wafer-Level Vacuum Packaging of Smart Sensors
The reach and impact of the Internet of Things will depend on the availability of low-cost, smart sensors-"low cost" for ubiquitous presence, and "smart" for connectivity and autonomy. By using wafer-level processes not only for the smart sensor fabrication and integration, but also for packaging, we can further greatly reduce the cost of sensor components and systems as well as further decreas...
متن کاملEffect of Freezing and Vacuum Packaging on Quality Properties of Pistachio Powder During Storage
Pistachio powder is a product used today in confectionery, ice cream, pistachio paste and other foods. Considering the higher rate of spoilage and oxidation in pistachio powder, developing methods to increase the shelf-life of this product is therefore important. In this study the effect of freezing and vacuum packaging on the quality characteristics of pistachio powder during storage was inve...
متن کاملVacuum Assisted Closure (VAC) at Home: Developing a New Concept
BACKGROUND The vacuum assisted closure (VAC) therapy has revolutionized the modern wound care. We developed a new concept of ‘VAC at home’ in order to decrease the hospital cost. METHODS The study was conducted in a private hospital from January 2009 to December 2010. Only those patients were included among whom the wounds were not complicated by concomitant injury and the patients were othe...
متن کاملHigh and Moderate-Level Vacuum Packaging of Vibratory MEMS
We report vacuum packaging procedures for low-stress die attachment and versatile hermetic sealing of resonant MEMS. The developed in-house infrastructure allows for both high and moderate-level vacuum packaging addressing the requirements of various applications. Prototypes of 100 μm silicon-on-insulator Quadruple Mass Gyroscopes (QMGs) were packaged using the developed process with and withou...
متن کاملPhotoelectric-Charging-Enhanced MEMS Electret Energy Harvester with Vacuum Packaging
A novel MEMS electret energy harvester charged with UV light after sealed in a vacuum package is proposed. By 265 nm UV irradiation, electrons are generated inside the package through the photoelectric effect. Uniform surface potential on sidewalls of the comb drives has been obtained. With a MEMS electret generator in a 60 Pa package, 2.28 μW has been obtained at 1 g and 740 Hz, which is 10 ti...
