Eco-designed conformable Inorganic Electronics to Improve the Smart Object End of Life: sensor's processing and applications

The plastic pollution is indisputable and technologies aiming to add flexible electronics onto objects have to take into consideration such environmental issue. Faced with this challenge, the development of technologies that comply with current standards such as WEEE (Waste Electric and Electronic Equipment) legislation is crucial. Green electronics based on fully biodegradable materials is under development but needs time to be put on the market. Meanwhile, inorganic electronic remains a good candidate. Consequently, it makes sense to transfer inorganic electronics onto objects before it dismantling and recoveries. Here, an eco-designed technology allowing the transfer of electronics onto objects is detailed. Silicon-based devices are transferred from polyimide substrate (PI) to water-soluble substrate (PVA: Poly(vinyl alcohol)). It is highlighted that the transfer of inorganic layers from PI to PVA substrate does not have a negative impact on the devices mechanical and electrical characteristics. To dem...
