Under the direction of the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, an in-house Fraunhofer project for development of biodegradable electronics began last year.
The Fraunhofer Institute for Electronic Nano Systems ENAS, the Fraunhofer Institute for Biomedical Engineering IBMT, the Fraunhofer Institute for Silicate Research ISC, and the Fraunhofer Resource Recycling and Strategy Project Group IWKS are working together on the project. The first results of the Fraunhofer FEP will be presented during Semicon Europe 2017 as part of productronica 2017 in Munich at the Silicon-Saxony joint booth, Nov. 14-17, 2017.
Electronic components that are completely broken down in a biological environment after a pre-defined operating life open up novel applications as well as ways for reducing their ecological footprint.
One enabling technology for such components is the manufacture of biodegradable conductive traces on biodegradable substrates using vacuum technologies. This technology was developed by Fraunhofer FEP.
A novel application area for these innovative electronic components, for example, is in the field of active medical implants that after expiration of their operating life are resorbed by tissue, thereby sparing the patient a second surgical intervention.
The Fraunhofer Gesellschaft e. V. is now funding the “bioElektron – Biodegradable Electronics for Active Implants” project through its in-house program (funding No. MAVO B31 301). The goal of the project is the development of essential components for biodegradable electronic parts that can be employed for example in an implant.
Conductor structures and organic thin-film transistors are being developed at Fraunhofer FEP using vacuum technology. Deposition of magnesium via thermal evaporation under high vacuum conditions is being used as an enabling technology for this purpose. The challenge consists of depositing this metal upon biodegradable polymer films that magnesium does not adhere sufficiently to under normal process control. By suitably pre-treating the substrates using a combination of drying, plasma treatment, and utilization of seed layers, finely structured high-quality conductor structures were able to be produced.
“We are now prepared to discuss these results with interested partners from industry and the scientific community during productronica 2017 at the Silicon-Saxony joint booth (Hall B1, Booth B1-416) in order to be able to implement them in current practical applications,” said Dr. Michael Hoffmann from Fraunhofer FEP and head of the bioElektron project.
