Abstract: The present invention relates to a patch-type tire status monitoring apparatus, which comprises a flexible substrate having an adhering side and a signal processing circuit; a tire status monitoring unit that is affixed to the non-adhering side of the flexible substrate; an antenna; and a wireless transmitting unit that is configured to transmit the signals sent by the tire status monitoring unit. The patch-type tire status monitoring apparatus of the present invention can be easily installed by utilizing the flexibility of the substrate to be firmly affixed to a rim. Since the apparatus does not require any exterior cover, the overall weight can be significantly reduced, which ultimately avoids any potential imbalance and misalignment problems on the wheels.
