Highlights in 2018

12/2018Paper featured on the cover page of Small
Our paper on the realization of visible light driven Ag/AgCl Janus particles is highlighted with an inside front cover page of Small.

In this work we present experimental and theoretical study of visible light-driven Ag/AgCl Janus micromotors revealing high-motility in pure H2O. We demonstrate that the propulsion efficiency is dependent on the intensity of visible light and complemented by the coupled effect of the plasmonic light absorption of Ag/AgCl and the efficient photochemical decomposition of AgCl. We address the application potential of Ag/AgCl micromotors in various physiological solutions and polluting agents.

11/2018Paper promoted as an Editor's Pick in Applied Physics Letters
Our recent work on the anomalous Hall-like transverse magnetoresistance in Au thin films on Y3Fe5O12 is chosen to be promoted as an Editor's Pick in Applied Physics Letters.

This work is a result of a fruitful collaboration between the HZDR and CIC nanoGUNE (group of Prof. F. Casanova).

The paper is published in Appl. Phys. Lett. 113, 222409 (2018). URL

11/2018Paper featured on the cover page of Nature Electronics
Our paper on the realization of highly compliant on-skin compass is highlighted with a cover page of the November issue of Nature Electronics.

An electronic-skin compass, which is fabricated on 6-um-thick polymeric foils and accommodates magnetic field sensors based on the anisotropic magnetoresistance effect, allows a person to orient with respect to Earth’s magnetic field and to manipulate objects in virtual reality. The cover shows a scanning electron microscopy image of the compass under a bending radius of 200 um.

11/2018Magnetosensitive e-skins lead the way
Augmented reality devices are destined to be an integral part of our information intensive society, assisting us to acquire data and process information. We envision that future augmented reality systems will rely on compliant on-skin interactive electronics. When equipped with motion tracking sensory systems, electronic skins would offer complimentary information on the surrounding and enable novel means of manipulating physical or even virtual objects. We here demonstrate the very first electronic skin capable of perceiving direction in space based on the interaction with geomagnetic field exclusively. Our highly compliant magnetosensory system enables real time tracking of the position of a body in space as well as the touchless manipulation of virtual objects based on the biomagnetic orientation as needed for virtual and augmented reality applications.

11/2018Paper featured on a frontispiece of Small
Our paper on the collective motion of visible-light-actuated AgCl-based Janus particles is highlighted with a frontispiece page of Small.

We demonstrate that visible-light-actuated plasmonic Ag/AgCl-based spherical Janus micromotors reveal efficient exclusion effect to surrounding passive beads in pure H2O. The exclusion efficiency is controlled by the number of single Janus particles composing micromotors. We determine the system-specific interaction parameter between Janus micromotors and passive beads. The availability of these system-specific information assures predictive power for further theoretical analysis of the complex dynamics of these heterogeneous active-passive systems.

01/2018Virtual reality goes magnetic
Augmented reality devices such as Smart Glasses are destined to be an integral part of our information intensive society, assisting us to acquire data and process information in an ever faster paced society. We demonstrate electronic skins capable of perceiving direction in space. Our highly compliant magnetosensory system enables real time tracking of the position of a body in space as well as the touchless manipulation of (virtual) objects based on the interaction with magnetic fields exclusively. We foresee exciting possibilities not only for business or gaming industries but also for safety and security applications, where the somatic manipulation of objects, e.g. turning regulation knobs located in a restricted environment, is undesirable or even prohibited.
