The study focuses on the optimization of PEDOT:PSS ink for the preparation of a hole transport layer. The ink was developed for the spiral bar coating technique and for subsequent organic photodetector preparation. In this study, the effect of various variables such as secondary dopant, surfactant, PEDOT:PSS complex ratio, and ink composition on selected characteristics such as conductivity, work function, charge carrier mobility, etc. is demonstrated.

This paper presents the design and characterisation of an antenna on a paper-based substrate. The antenna is designed on a nanocellulose foil optimised with a highly conductive ink based on silver nanoparticles. The electrical and dielectric properties of the materials were characterised prior to the antenna simulation. The antenna is designed to operate at the ISM 868 MHz frequency band and has a maximum gain of +1.7 dBi. Its development is part of the first step in the implementation of a flexible battery-free geolocation tag, remotely powered by UHF Energy sources in the European RFID spectrum between 865.6 MHz and 867.6 MHz. An accurate characterisation procedure was carried out and the results show good agreement with the simulations.

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.
