Printed electronics and paper electronics are relevant topics that promise a tremendous increase and their incorporation in gadgets for daily applications with a very short lifespan. This will fulfill special niches such as the Internet of Things and smart packaging, for instance. However, the printed electronics applications must not contribute further to the huge amount of e-waste gener…
The silicon electronics have shaped the modern society inseparable from everyone daily life. However, this technology is not compatible with the demand for the implementation of a low-cost electronics that produce lightweight, flexible, transparent and large-area devices. In this context, printed electronics emerges as an alternative that aims to meet the aforementioned demands and that a…
ZnO thin films produced by the pyrolysis of zinc acetate dihydrate, sprayed on heated substrates, are naturally n-doped due to structural defects like oxygen vacancy, interstitial zinc, and others. Since the ZnO band gap is about 3.3 eV, ultraviolet radiation (UVR) photons can generate electron-hole pairs, increasing the number of electrons in the conduction band. These photo-generated el…
The development of inverter circuits represents one important research topics on organic electronics, since they are the building blocks for digital electronics. The production of flexible and printable circuits has been attracting even more attention due to its technological power on several applications, such as displays. The inverter circuits that exhibit the best performances and stab…

With population growth and the high demand for food production, agriculture faces significant sustainability challenges, with heavy metal contamination emerging as a serious global public health issue. In this context, there is a growing interest in developing sensors that can identify these contaminants in a sustainable and cost-effective manner. This project proposes the study of "Elect…
The advent of organic electronics brings interest in new electronic modalities, such as printed flexible electronics, which have become alternatives to silicon electronics. These organic electronics stand out in some specific niches, such as smart packaging, wearable electronics, and applications for the Internet of Things (IoT). However, the concern over the increasing electronic waste a…
Sustainable printed electronics is an area that seeks to reduce the environmental impact of electronic device production and disposal. Printed electronics use printing techniques on materials such as paper, polymer, and fabric to create electronic circuits and components. In addition, printed electronics offer the possibility of creating lighter, more flexible, and portable devices that c…

The performance of printed electronics applications depends fundamentally on printing good diodes that are considered the "quintessential" element of electronics. This project proposes to study a hybrid Schottky diode prepared by the spray deposition technique, with structure PEDOT:PSS/ZnO/AZO, in which gold nanoparticles (AuNPs) are added to the ZnO film. The AC and DC characterization w…
The flexible and printed organic electronics stands out in the technological development scenario. Its main applications are on large-area devices, with low processability temperature and low production cost. Furthermore, it is desirable to fabricate these devices using materials and methods compatible with printing techniques. Among the most utilized electronic components, the transistor…
Ultraviolet radiation (UVR) is beneficial for people's health, however, if the exposure is excessive it can cause diseases as, for instance, skin cancer. Brazil is one of the countries with the biggest skin cancer incidence in the world. For this reason, UVR sensor devices, printed on personal adornments or in clothing is very important. Zinc oxide (ZnO) is a semiconductor material widely…

The exponential growth of electronic waste poses a significant challenge for electronics, which must adapt to more sustainable pathways, particularly in applications with very short life cycles. In the search for low-cost deposition techniques and alternative materials, new niches in electronics have emerged, such as printed and flexible electronics, which allow conformity to packaging an…
The search for sustainable alternatives to silicon-based electronics and conventional processes has fostered the investigation of new possibilities for electronic devices, such as transistors based on eco-friendly and abundant nano-scale materials on flexible and conformable substrates. However, devices designed for disposable applications should be easy to recycle and have the lowest pos…
The project developed in Brazil aims to investigate how the supramolecular arrangement of the active layer of organic thin films influences the electro-optical properties of organic field-effect transistors with electrolyte in the gate (EGOFETs) and Schottky diode. Our preliminary results suggest that the type of molecular aggregate - related to À-stacking interaction -, the preferential …
Recently, the electronics industry has transformed the world in such a way that its products have become essential to everyday life. On the other hand, the growing use of electronic devices and gadgets has increased the generation of electronic waste (e-waste). Thus, there is an urgent need to develop biodegradable electronic devices and components using techniques that also cause less da…
