SENSOR TAG AND MANUFACTURING METHOD FOR SENSOR TAG

摘要

A sensor tag (10) includes an antenna (102) and connection conductors (103) formed on a surface of a flexible substrate (101). A sensing element (110) is mounted on land conductors (131) of the connection conductors (103). The sensing element (110) is composed of a crystal vibrator (111) and an RFIC (112). The crystal vibrator (111) receives an excitation signal from the outside and generates a resonance signal of a resonant frequency corresponding to the sensed temperature. Equivalent circuit constant information including at least an equivalent inductance (Lxs) or an equivalent capacitance (Cxs) of the crystal vibrator (111) are stored in the RFIC (112).

1. A sensor tag comprising:
a resonator that generates a resonance signal corresponding to a sensed physical quantity; an antenna that radiates the resonance signal; and a connection conductor that connects the antenna and the resonator, wherein the sensor tag is formed based on at least an equivalent inductance or an equivalent capacitance of the resonator.
