Disclosed are a patch-type passive surface acoustic wave sensing device and an intelligent tire, wherein the patch-type passive surface acoustic wave sensing device comprises a surface acoustic wave sensor (101) and at least comprises a first rubber sheet (201) and a second rubber sheet (202), the cross section of each of the first rubber sheet (201) and the second rubber sheet (202) is larger than that of the surface acoustic wave sensor (101), the bottom part of the surface acoustic wave sensor (101) is located on the upper surface of the first rubber sheet (201), a first central hole (204) allowing the surface acoustic wave sensor to penetrate therethrough is formed in the centre of the second rubber sheet (202), the surface acoustic wave sensor (101) penetrates the first central hole (204), the second rubber sheet (202) is fixedly connected to the upper surface of the first rubber sheet (201), the surface acoustic wave sensor (101) comprises pins (102) arranged at the bottom thereof, free ends of the pins (102) are connected to an antenna (103), and the antenna (103) and some of the pins (102) are buried in the first rubber sheet (201). The intelligent tire comprises the patch-type passive surface acoustic wave sensing device which is fixed onto the inner wall of the tire. The patch-type passive surface acoustic wave sensing device requires no power supply, has the advantages of a small size and low weight, and has certain abilities of high temperature and high pressure resistance. |
