Title:
SENSOR TAG AND METHOD FOR MANUFACTURING SENSOR TAG
Document Type and Number:
WIPO Patent Application WO/2014/129069
Kind Code:
A1
Abstract:
A sensor tag (10) is provided with an antenna (102) and connecting conductors (103), said antenna (102) and connecting conductors (103) being formed on the surface of a flexible substrate (101). A sensing element (110) is mounted on land conductors (131) that are part of the connecting conductors (103). Said sensing element (110) comprises a crystal oscillator (111) and an RFIC (112). The crystal oscillator (111) receives an external excitation signal and generates a resonance signal at a resonant frequency corresponding to a sensed temperature. The RFIC (112) stores equivalent-circuit-constant information including at least the equivalent inductance (Lxs) or equivalent capacitance (Cxs) of the crystal oscillator (111).
