“…et al in 2018 [ 108 ], who not only focused on the chemical stability of the electrical properties of such a material when used in ambient conditions, but also demonstrate an interest in increasing the mechanical resistance of devices such as FET upon repetitive bending. More original was the work of Seck et al, who published an almond gum dielectric to be used in an OFET [ 109 ]. Almond gum is a natural and biodegradable material, which is water-soluble, which they show to present good dielectric properties.…”

Nowadays, sensor devices are developing fast. It is therefore critical, at a time when the availability and recyclability of materials are, along with acceptability from the consumers, among the most important criteria used by industrials before pushing a device to market, to review the most recent advances related to functional electronic materials, substrates or packaging materials with natural origins and/or presenting good recyclability. This review proposes, in the first section, passive materials used as substrates, supporting matrixes or packaging, whether organic or inorganic, then active materials such as conductors or semiconductors. The last section is dedicated to the review of pertinent sensors and devices integrated in sensors, along with their fabrication methods.

“…[54,74,147] Other architectures used for the implementation of green OFETs are the bottom-gate bottom-contacts (BG-BC) and top-gate top-contact (TG-BC) structures. [156][157][158][159] BG-BC and TG-BC architectures have found application also for the implementation of ion-gated transistors, including both EGOFETs and OECTs. [69,74,[160][161][162] Since in ion-gated transistors an ionically-conductive and electrically-insulating material is used for the electrostatic coupling of the gate with the channel, a simple yet effective implementation approach commonly used for EGOFETs and OECTs is based on lateral-gate bottomcontact (LG-BC) architecture.…”

Intelligent objects, autonomous factories and humans browsing the real world with artificial technology‐based capabilities is not the movie set of a new saga but what is going to happen with next‐generation electronics and bioelectronics fabricated with emerging materials, technologies, and devices. The emergence of (bio)electronics as a ubiquitous feature of an advanced modern society is posing the challenge of managing an ever‐increasing amount of e‐waste, also making the recovery more and more difficult. Thus, new design approaches are required considering that a possibly small but significant fraction of mass‐scale e‐products is inherently impossible to recover. In this perspective, organic materials and technologies can provide important solutions. This review presents and analyses green materials and technologies underpinning the development of sustainable organic transistors, which promise to become key components for Earth‐safe wide‐spread electronics and bioelectronics.

Background. Currently, there is a significant number of technologies and materials in the world that are used to manufacture flexible electronics devices. Therefore, a review of various technologies and materials for the manufacture of flexible sensors, which would not be inferior in terms of sensitivity to their solid-state counterparts, is in demand. In addition, most modern flexible electronics technologies are based on the use of artificial polymers, the production of which pollutes the environment and which need to be disposed of at the end of its service life. Therefore, there is an urgent need to find an alternative to artificial polymers, environmentally friendly material. Objective. The purpose of the paper is to determine design and technological features of manufacturing and application of flexible and biodegradable electronic sensors. Methods. The article analyses, classifies and compares different technologies and materials for the manufacture of flexible sensors, which would not be inferior to their solid-state counterparts in terms of sensitivity. The technological features of synthesis and the main characteristics of flexible sensors made on the basis of artificial and biodegradable materials were also compared in the paper. Results. The design and technological features of manufacturing as well as application of flexible electronic sensors in comparison with their solid-state analogues were determined in the paper. Three groups of substrate materials that can be used for the synthesis of flexible sensors have been identified and their performance characteristics analysed. A comparison of different production techniques for flexible electronic sensors in terms of environmental friendliness, cost and manufacturability is carried out. Conclusions. The most promising biodegradable material, on the surface of which one can create a flexible sensor, is nanocellulose. Different types of printing are the most promising production technique for the manufacture of such devices, because they are cheap and can provide high productivity. Based on the obtained results, it is possible to improve the existing and develop new methods of creating flexible electronics devices that do not require recycling.
