Abstract

The authors discussed the principle of wireless sensing with passive SAW devices and investigated binary SAW sensors and other SAW radio sensors for the non-contact measurement of temperatures, pressures and torques. An RF identification system for the Munich subway, a SAW sensor system for the diagnosis and control of electric motors and a temperature monitoring system for high voltage surge arresters are the applications which were presented. Finally a low-cost radar unit for domestic applications was described
