“…Consequently, applying SAW sensors in a tyre pressure and temperature monitoring system has been explored for their advantages in the sense that they have very small size and weight, can pass signals wirelessly, receive the required power wirelessly by the energy of the RF field (and therefore no local battery is needed), and can resist harsh environment conditions (Pohl et al, 1997(Pohl et al, , 1998Xiangwen et al, 2004;Zhang et al, 2004;Li et al, 2010). The working principle of SAW sensors is explained in detail in chapter five in Yurish and Gomes (2005).…”
