AbstractA new equivalent circuit for the vibratory gyroscope and an analyzing and controlling method for the vibration mode axis of the vibrator have been studied. The vibrator of this gyroscope consists of a piezoelectric-ceramic cylinder. On its outer cylindrical surface, interdigital electrodes are formed. And these electrodes are used for poling, AC excitation as well as detection. In order to prevent some deviation of the performance of the gyroscope due to the adhesion process, these electrodes are directly printed on the cylinder surface.By changing the electrodes pattern and making a groove on the surface of the vibrator, the vibration mode axis can be easily controlled. Optimum design suited for demanded specifications can then be obtained.

The objective of this study is to extend the application of the spray-coated tactile sensor, ScoTacS, which is being developed by the authors and can be constructed simply by “coating” with a spray gun, from one dimension to two dimensions, and further to configure it into various shapes such as a ring. This sensor is constructed by coating three layers-conductive, piezoelectric, and resistive films-in sequence. It is based on a unique principle by which the contact position is detected from the delay time, i.e., the time difference between the arrivals of peaks in the output signals. As the delay time varies with the contact position, it can be used to estimate the contact position. In this paper, after analyzing the characteristics of one-dimensional sensors, such as linear and ring sensors, we present the equivalent circuit models and experimental results of a two-dimensional sensor fully coated on a cylinder.
