Due to its potential to make computers faster and smartphones more efficient, spintronics is considered a promising concept for the future of electronics. In a collaboration including the Max Planck Institute for Intelligent Systems (MPI-IS) and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a team of researchers has now successfully generated so-called spin waves much more easily and efficiently than was previously deemed possible...

Smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a KAIST research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source.

To ease out the problem of external power sources and enhance the practicability of wearable displays, Professor Kyung Cheol Choi from the School of Electrical Engineering and his team fabricated their wearing display modules on real textiles that integrated polymer solar cells (PSCs) with organic light emitting diodes (OLEDs).

PSCs have been one of the most promising candidates for a next-generation...

Using a new type of dual polymer material capable of responding dynamically to its environment, Brown University researchers have developed a set of modular hydrogel components that could be useful in a variety of “soft robotic” and biomedical applications.

The components, which are patterned by a 3D printer, are capable of bending, twisting or sticking together in response to treatment with certain chemicals. For a paper published in the journal Polymer Chemistry, the researchers demonstrated a soft gripper capable of actuating on demand to pick up small objects...

Nanoscale patterning could enable precise manipulation of objects on many scales. Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects’ surfaces. Though still theoretical, the work is a step toward developing a spacecraft that could reach the nearest planet outside of our solar system in 20 years, powered and accelerated only by light.

A paper describing the research appears online in the March 18 issue of the journal Nature Photonics...
