Author Affiliations +
A great number of design concepts of surface acoustic wave (SAW)-based gyroscopes was proposed through the last decade mainly due to their unique robustness and ability to survive extremely high shocks. At the same time, these devices are small, cheap and easy to produce. Later publications offered a novel idea of constructing a fully passive and wireless gyroscope using SAW-based elements. Although this idea is very attractive, proposed design concepts rise a number of questions. This paper is dedicated to give a short overview of existing design concepts, focusing on details of its operation. Moreover, a new design concept utilizing a single delay line and a phase detector is proposed.
