Dissolvable Silicon Circuits and Sensors

Transient Electronics that Dissolve in Water Usher in Next Generation of Devices, from Green Technologies to Medical Implants

Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign.

A new generation of transient electronic devices function in water but dissolve when their function is no longer needed.

Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, including most recently intracranial monitors for patients with traumatic brain injury.

The advances suggest a new era of devices that range from green consumer electronics to ‘electroceutical’ therapies, to biomedical sensor systems that do their work and then disappear.

John A. Rogers’ research group at the Department of Materials Science and Engineering Frederick Seitz Materials Research Laboratory is leading the development of such concepts, along with all of the required materials, device designs and fabrication techniques for applications that lie beyond the scope of semiconductor technologies that are available today.

“Our most recent combined developments in devices that address real challenges in clinical medicine and in advanced, high volume manufacturing strategies suggest a promising future for this new class of technology,” said Rogers. He will present these and other results at the AVS 61st International Symposium & Exhibition, being held November 9-14, 2014 in Baltimore, Md.

Practical applications might include: bioresorbable devices that reduce infection at a surgical site. Other examples are temporary implantable systems, such as electrical brain monitors to aid rehabilitation from traumatic injuries or electrical simulators to accelerate bone growth. Additional classes of devices can even be used for programmed drug delivery, Rogers said.

Such envisioned uses are all best satisfied by devices that provide robust, reliable, high performance operation, but only for a finite period of time dictated, for example, by the healing process—they are not only biologically compatible, but they are biologically punctual, performing when and as the body needs them.

After their function has been fulfilled, they disappear through resorption into the body, thereby eliminating unnecessary device load, without the need for additional surgical operations. In terms of consumer electronics, the technology holds promise for reducing the environmental footprint of the next generation of “green” devices.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
