Abstract

The conventional water pressure measurement method requires batteries as power sources for pressure sensors. This method is unreliable because the risk of damaging batteries is high especially in harsh environment. This paper provides a novel method that wireless passive surface acoustic wave (SAW) pressure sensor is introduced for water pressure measurement. Wireless passive SAW sensors do not need direct power supply. Therefore, batteries are not required by using this new technology. The main types of wireless passive SAW sensors are reviewed. The performance of wireless passive SAW sensor is tested. The water pressure sensing framework is proposed
