Download or read book Piezoresistive Effect of p Type Single Crystalline 3C SiC written by Hoang-Phuong Phan and published by Springer. This book was released on 2017-04-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the piezoresistance in p-type 3C-SiC, which it investigates using experimental characterization and theoretical analysis. The gauge factor, the piezoresistive coefficients in two-terminal and four-terminal resistors, the comparison between single crystalline and nanocrystalline SiC, along with the temperature dependence of the piezoresistive effect in p-type 3C-SiC are also discussed. Silicon carbide (SiC) is an excellent material for electronic devices operating at high temperatures, thanks to its large energy band gap, superior mechanical properties and extreme chemical inertness. Among the numerous polytypes of SiC, the cubic single crystal, which is also well known as 3C-SiC, is the most promising platform for microelectromechanical (MEMS) applications, as it can be epitaxially grown on an Si substrate with diameters of up to several hundred millimeters. This feature makes 3C-SiC compatible with the conventional Si-based micro/nano processing and also cuts down the cost of SiC wafers. The investigation into the piezoresistive effect in 3C-SiC is of significant interest for the development of mechanical transducers such as pressure sensors and strain sensors used for controlling combustion and deep well drilling. Although a number of studies have focused on the piezoresistive effect in n-type 3C-SiC, 4H-SiC and 6H-SiC, comparatively little attention has been paid to piezoresistance in p-type 3C-SiC. In addition, the book investigates the piezoresistive effect of top-down fabricated SiC nanowires, revealing a high degree of sensitivity in nanowires employing an innovative nano strain-amplifier. The large gauge factors of the p-type 3C-SiC at both room temperature and high temperatures found here indicate that this polytype could be suitable for the development of mechanical sensing devices operating in harsh environments with high temperatures.

Download or read book Design and optimization of a novel tri axial miniature ear plug piezoresistive accelerometer with nanoscale piezoresistors written by Marco Messina and published by GRIN Verlag. This book was released on 2017-12-12 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2013 in the subject Design (Industry, Graphics, Fashion), grade: N/A, Cranfield University, language: English, abstract: This work aims at the advancement of state-of-art accelerometer design and optimization methodology by developing an ear-plug accelerometer for race car drivers based on a novel mechanical principle. The accelerometer is used for the measurements of head acceleration when an injurious event occurs. Main requirements for such sensor are miniaturization (2×2 mm), because the device must be placed into the driver earpiece, and its measurement accuracy (i.e. high sensitivity, low crosstalk and low nonlinearity) since the device is used for safety monitoring purpose. A micro-electro-mechanical system (MEMS)-based (bulk micromachined) piezoresistive accelerometer was selected as enabling technology for the development of the sensor. The primary accelerometer elements that can be manipulated during the design stage are: the sensing element (piezoresistors), the micromechanical structure and the measurements circuit. Each of these elements has been specifically designed in order to maximize the sensor performance and to achieve the miniaturization required for the studied application. To achieve accelerometer high sensitivity and miniaturization silicon nanowires (SiNWs) as nanometer scale piezoresistors are adopted as sensing elements. Currently this technology is at an infancy stage, but very promising through the exploitation of the “Giant piezoresistance effect” of SiNWs. This work then measures the potential of the SiNWs as nanoscale piezoresistors by calculating the major performance indexes, both electrical and mechanical, of the novel accelerometer. The results clearly demonstrate that the use of nanoscale piezoresistors boosts the sensitivity by 30 times in comparison to conventional microscale piezoresistors. A feasibility study on nanowires fabrication by both top-down and bottom-up approaches is also carried out. The micromechanical structure used for the design of the accelerometer is an optimized highly symmetric geometry chosen for its self-cancelling property. This work, for the first time, presents an optimization process of the accelerometer micromechanical structure based on a novel mechanical principle, which simultaneously increases the sensitivity and reduces the cross-sensitivity progressively. In the open literature among highly symmetric geometries no other study has to date reported enhancement of the electrical sensitivity and reduction of the cross-talk at the same time.

Download or read book Sensing the Perfect Tomato written by Denise Wilson and published by CRC Press. This book was released on 2019-04-19 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fresh? Juice? Paste? Canned? Stewed? Diced? Pureed? Sun Dried? Salsa? Sauce? Ketchup? Rare is the cuisine that does not make use of the tomato in some way, shape, or form, and the resulting culinary popularity of the tomato has led to its proliferation in fields and farms around the world. While some may still argue whether the tomato is a fruit or a vegetable, few would argue that tomato crops are highly lucrative, attractive to farmers in both developing and developed countries and on large and small farms alike. In fact, for those crops with significant global volume and market share, tomatoes are the highest valued among those crops that lack an affiliation to mind-altering drugs. But, the tomato can be a persnickety critter. The tomato doesn’t like it too hot, too chilly, too wet, too dry, or too fertile. Many don’t ripen at the same time. Most are easily bruised. And, the selective breeding that has yielded a larger, more attractive, and deep red tomato has also mercilessly drained much of the taste and flavor from a once sweet and delectable fruit. Enter the world of sensors and modern sensing technology. The Internet of Things (IOT), when using well chosen, well networked, and well aggregated sensors, has shown tremendous potential to support precision agriculture, providing a more detailed picture of crops than was previously possible using conventional crop monitoring techniques. But, the stringent resources and tight profit margins that are a fact of life among many tomato growing operations, large and small, mean that sensor technologies must be chosen and used carefully. There is no doubt that each sensor must earn its keep in producing the perfect tomato. With that in mind, this book explores key opportunities to marry the potential of sensors that are networked within the IOT to the needs of tomato production in ways that are economically fruitful, technologically robust, and sustainable overall.
