The fundamental requirement of a competent tactile sensor for manipulating an object is to determine the magnitude and the position of an applied force on it. In addition, it is important to determine orientation of the object in relation to the tactile sensor. In order to achieve these goals, most investigators have attempted to design a tactile sensor using an array of sensing elements arranged in matrix form. There are several problems associated with this type of tactile sensors. These problems include cross-talk between sensing elements, fragility, and complexity. This thesis reports on the design, modeling, fabrication and testing of a membrane tactile sensing system with only four sensing elements. By using membrane stress combined with triangulation approach, it is shown that it is possible to overcome the above problems. The prototype sensor consists of a single film of 25 micron thick Polyvinylidene Fluoride (PVDF) film, which is held between two 12 mm-thick flat Plexiglass plates, each with a 90 mm-diameter center hole. Four square sensing elements, each 3 min side, were fabricated around the center of the membrane. The fabrication of the sensing elements is performed using photolithographic and etching techniques. By applying force with a probe of various shapes and sizes at various points away from the sensing elements, and using a geometric mapping process, the sensor is calibrated. As the result of calibration various isocharge contours were drawn. Using both finite element and experimental analysis, it is shown that it is possible to determine the position, orientation and the magnitude of the applied load though various flat shaped probes, by using only four sensing elements. The experimental and the finite element results are compared. It is shown that there is a good correlation between the finite element predictions and experimental data.

Ultrasonic transducers are key components in sensors for distance, flow and level measurement as well as in power, biomedical and other applications of ultrasound. Ultrasonic transducers reviews recent research in the design and application of this important technology.Part one provides an overview of materials and design of ultrasonic transducers. Piezoelectricity and basic configurations are explored in depth, along with electromagnetic acoustic transducers, and the use of ceramics, thin film and single crystals in ultrasonic transducers. Part two goes on to investigate modelling and characterisation, with performance modelling, electrical evaluation, laser Doppler vibrometry and optical visualisation all considered in detail. Applications of ultrasonic transducers are the focus of part three, beginning with a review of surface acoustic wave devices and air-borne ultrasound transducers, and going on to consider ultrasonic transducers for use at high temperature and in flaw detection systems, power, biomedical and micro-scale ultrasonics, therapeutic ultrasound devices, piezoelectric and fibre optic hydrophones, and ultrasonic motors are also described.With its distinguished editor and expert team of international contributors,Ultrasonic transducers is an authoritative review of key developments for engineers and materials scientists involved in this area of technology as well as in its applications in sectors as diverse as electronics, wireless communication and medical diagnostics. - Reviews recent research in the design and application of ultrasonic transducers - Provides an overview of the materials and design of ultrasonic transducers, with an in-depth exploration of piezoelectricity and basic configurations - Investigates modelling and characterisation, applications of ultrasonic transducers, and ultrasonic transducers for use at high temperature and in flaw detection systems
