This paper presents a preliminary study for the construction of an in-mould smart tag as a robust flexible label with a radiofrequency wireless power transmission system and enhanced geolocation features. The proposed flexible geolocation tag is realised by means of a specific production process applied over printed antennas and hybridized rigid control module. Advanced materials such as highly conductive inks and nanocellulose-based substrates, as well as innovative manufacturing processes covered by the in-mould electronics framework, are investigated. The effect of the thermoplastic used for in-mould process on the antenna is explored by simulations and experimental validation.
