Abstract
A patch-type passive acoustic waving sensing device includes a surface acoustic wave sensor and at least a first and second rubber sheets. A cross-section of each of the first and second rubber sheets is larger than that of the surface acoustic wave sensor. A bottom of the surface acoustic wave sensor is on an upper surface of the first rubber sheet, and a first central hole allowing the surface acoustic wave sensor to penetrate therethrough is formed in a center of the second rubber sheet. The surface acoustic wave sensor penetrates the first central hole, and the second rubber sheet is fixedly connected to the upper surface of the first rubber sheet. The surface acoustic wave sensor includes pins at the bottom thereof such that free ends of the pins are connected to an antenna, and the antenna and some of the pins are inside the first rubber sheet.
