A flexible sensor unit for embedding in a tire (10) and a respective tire (10) is disclosed. The flexible sensor unit (100) comprises a plurality of individual circuit boards (102A, 102B, 102C, 102D), wherein each circuit board (102A, 102B, 102C, 102D) includes at least one electronic component. The at least one electronic component includes at least one of a radio frequency identification integrated circuit (106), at least one a microcontroller unit (108), at least one sensor (110), at least one power source (112) and at least one boost converter (114). A plurality of electrically conductive flexible connecting ribbons (104A, 104B) or structures is provided, each connecting ribbon (104A, 104B) or structure extending between selected ones of the individual circuit boards (102A, 102B, 102C, 102D). An end ribbon (116) or structure is electrically connected to at least one of the circuit boards (102A, 102B, 102C, 102D) and an antenna (118) being disposed on the end ribbon (116). The antenna (116) is configured to transmit data from the at least one sensor (110) as processed by the microcontroller unit (108) and to transmit identification data from the radio frequency identification integrated circuit (106), to an external reader.
