Available in PDF, EPUB and Kindle. Book excerpt: 1 1. 1 Introduction The (signal processing and storage) capacity ofthe human brain enables us to become powerful autonomous beings, but only if our brains operate in conjunction with (at least some of) our senses and muscles. Using these organs, we can interact with our environment, learn to adapt, and improve important aspects of our life. Similarly, the signal processing capabilities of modern electronics (computers) could be combined with electronic sensors and actuators to enable interaction with, and adaptation to, the (non-electrical) environment. This willlead to smarter and more powerful automated tools and machines. To facilitate and stimulate such a development, easy-to-use low-cost sensors are needed. The combination of electronic interface functions and a sensor in an integrated smart sensor, that provides a standard, digital, and bus-compatible output, would simplify the connection of sensors to standard electronic signal processors (microcontrollers, computers, etc. ). Currently, the calibration procedure, required for standardization of the sensor output signal level, contributes largely to the production costs of accurate sensors. To enable automation of the calibration procedure, and hence reduce the sensor fabrication costs, a digital calibrationjunction should be included in the smart sensor.

Book Synopsis Micro Mechanical Transducers by : Min-Hang Bao
Download or read book Micro Mechanical Transducers written by Min-Hang Bao and published by Elsevier Science Limited. This book was released on 2000 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some years ago, silicon-based mechanical sensors, like pressure sensors, accelerometers and gyroscopes, started their successful advance. Every year, hundreds of millions of these devices are sold, mainly for medical and automotive applications. The airbag sensor on which research already started several decades ago at Stanford University can be found in every new car and has saved already numerous lives. Pressure sensors are also used in modern electronic blood pressure equipment. Many other mechanical sensors, mostly invisible to the public, perform useful functions in countless industrial and consumer products. The underlying physics and technology of silicon-based mechanical sensors is rather complex and is treated in numerous publications scattered throughout the literature. Therefore, a clear need existed for a handbook that thoroughly and systematically reviews the present basic knowledge on these devices. After a short introduction, Professor Bao discusses the main issues relevant to silicon-based mechanical sensors. First a thorough treatment of stress and strain in diaphragms and beams is presented. Next, vibration of mechanical structures is illuminated, followed by a chapter on air damping. These basic chapters are then succeeded by chapters in which capacitive and piezoresistive sensing techniques are amply discussed. The book concludes with chapters on commercially available pressure sensors, accelerometers and resonant sensors in which the above principles are applied. Everybody, involved in designing silicon-based mechanical sensors, will find a wealth of useful information in the book, assisting the designer in obtaining highly optimized devices.
Book Synopsis Automated Calibration OfMulti-Sensor Optical ShapeMeasurement System by : Olatokunbo Omodele Ogundana

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-sensor optical shape measurement systems (SMS) based on the fringe projection method and temporal phase unwrapping has recently been commercialised as a result of its easy implementation, computer control using a spatial light modulator, and fast full-field measurement. The main advantage of a multi-sensor SMS is the ability to make measurements for 3600 coverage without the requirement for mounting the measured component on translation and/or rotation stages. However, for greater acceptance in industry, issues relating to a user-friendly calibration of the multi-sensor SMS in an industrial environment for presentation of the measured data in a single coordinate system need to be addressed. The calibration of multi-sensor SMSs typically requires a calibration artefact, which consequently leads to significant user input for the processing of calibration data, in order to obtain the respective sensor's optimal imaging geometry parameters. The imaging geometry parameters provide a mapping from the acquired shape data to real world Cartesian coordinates. However, the process of obtaining optimal sensor imaging geometry parameters (which involves a nonlinear numerical optimization process known as bundle adjustment), requires labelling regions within each point cloud as belonging to known features of the calibration artefact. This thesis describes an automated calibration procedure which ensures that calibration data is processed through automated feature detection of the calibration artefact, artefact pose estimation, automated control point selection, and finally bundle adjustment itself. The process of calibration artefact selection is discussed, with the objective of developing a low cost artefact, with appropriate geometric and material properties such as unobstructed viewing by sensors, low coefficient of thermal expansion and non-specular surface finish. Automated detection of calibration artefact features is investigated, for enhancing the ease, speed, and accuracy of calibration. A novel 3-D Hough transform based on an optimised sparse 3-D matrix model is described, including methods developed for efficient peak detection in the Hough accumulator space. The calibration results of a two-camera and two-projector optical SMS based on multiple poses of the respective calibration artefacts developed, are discussed. A comparison of usage of the calibration artefacts is also made in order to assess their practicable use in an industrial environment. Based on acquired shape data of one of the artefacts, calibration accuracy of about one part in 5,000 was achieved. In applications for product inspection and quality assessment, the measured data needs to be presented in a form that provides for visualisation on a computer. A method for efficiently tessellating the measured point cloud using sensor pixel neighbourhood information is described. This method provides for the presentation of the measured point cloud data in industry accepted file formats. In addition, the measured data of a component may need to be compared against an idealised model of the component e.g. a computer-aided design (CAD) model. Methods for matching the measured data to a CAD model are therefore also discussed. The results of calibrating a multi-sensor SMS at an industrial site are presented. In spite of a less well controlled environment, a calibration accuracy of about one part in 1,600 was achieved, with the SMS subsequently used as a valuable tool for measuring out-of-plane displacement during a series of structural tests.

Book Synopsis Hyper-sensitive MEMS Pressure Sensor Array for Microscale Bubble Pressure Measurement by : Yash Rajan Rasaikar
Download or read book Hyper-sensitive MEMS Pressure Sensor Array for Microscale Bubble Pressure Measurement written by Yash Rajan Rasaikar and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As technology is advancing, more complex, efficient, and powerful devices are being made. These powerful devices generate a lot of heat which needs to be taken out to maximize their performance. Hence, efforts are being made to improve cooling techniques for these devices. Boiling is one such technique used in the cooling of devices. The heat transfer performance in the flow boiling systems is higher than that in pool boiling systems. With a simple add-on tapered manifold over a plain surface, we can convert pool boiling to flow boiling. This study will lead to improved performance and reliability of microelectronic devices, supercomputers, server chips, etc. The forces from bubbles growing can provide a pumpless, self-sustained unidirectional flow effectively transforming pool boiling into the extremely efficient flow boiling, resulting in energy savings. MEMS pressure sensor array will be mounted at the end of tapered manifold to map the pressure field around a nucleating bubble. The thesis describes the design, fabrication, packaging, and testing of a bulk micromachined sensor array that is capable of monitoring the pressure progression of a bubble. The sensor utilizes an extremely thin 225 nm square Si3N4 diaphragm which is produced by etching away the bulk silicon with XeF2 through holes present in the diaphragm. A unique process flow was developed to achieve the diaphragm thickness in nanometers. Four polysilicon piezoresistors, mounted on the surface of the diaphragm, where the stress is maximum, are used by the sensor. The thesis also discusses the results obtained from the response of the fabricated sensor. Various attempts were made to get a voltage output in response to applied pressure. These values were acquired over a number of experiments repeated at similar experimental conditions to demonstrate the repeatability of the calibration data. The value of sensitivity, derived from the slope of the linear calibration plot of Vout (V) vs. Pressure (Pa), is 5.26 [micro]V/Pa, which is very close to the required target hyper-sensitivity of 5 [micro]V/Pa."--Abstract.
