Biodegradable electronics

13.10.2017

Under the direction of the Fraunhofer FEP, an in-house Fraunhofer project for development of biodegradable electronics was begun last year. The Fraunhofer Institutes ENAS, IBMT, ISC, and the Fraunhofer Project Group IWKS are working together on the project. 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 in Hall B, Booth No. B1-416, November 14-17, 2017.

Electronic devices 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 devices is the production 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.

This includes in particular

- biodegradable conductor structures
- biodegradable electrodes for collecting electrical signals or delivering electrical stimulation
- biodegradable thin-film transistors and circuitry
- biodegradable barrier coatings as moisture and gas barriers, and electrical insulation layers


These elements will be monolithically integrated into a flexible thin-film device.

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.

Magnesium is known for being a biodegradable and biologically compatible metal that is already employed in clinical environments as an absorbable implant material. The challenge consists of depositing this metal onto biodegradable polymer films that magnesium does not adhere sufficiently to under normal processing conditions. By suitably pre-treating the substrates using a combination of drying, plasma treatment, and utilization of seed layers, finely structured high-quality conductor structures have been 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”, explains Dr. Michael Hoffmann from Fraunhofer FEP and head of the bioElektron project.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...

Im Focus: A molecular switch may serve as new target point for cancer and diabetes therapies

If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz- Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases. The results of the study have just been published in the prestigious scientific journal 'Molecular Cell'.

Cell growth and cell differentiation as well as the release and efficacy of hormones such as insulin depend on the presence of lipids. Lipids are small...
