| Towards self-sensing soft robots with electrochemically driven pumps Posted: 08 Feb 2022 05:50 AM PST Soft robots have received much attention recently due to their adaptability and safety. However, the fluidic systems used in these robots continue to use pumps that are large, heavy, and noisy. Now, researchers report a fluid pump driven by electrochemical reactions that are simple, lightweight, silent, and enable self-sensing actuation, with potential applications in wearable technology and touch display devices. |
| Simulation training helps hone advanced surgical skills, international trial finds Posted: 08 Feb 2022 05:50 AM PST A large-scale study has found that simulation-based surgical training produced an increase of surgeons' skills for more complex surgeries. |
| Researchers use tiny magnetic swirls to generate true random numbers Posted: 07 Feb 2022 09:48 AM PST Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. |
| Nanowires under tension create the basis for ultrafast transistors Posted: 07 Feb 2022 08:26 AM PST Nanowires have a unique property: These ultra-thin wires can sustain very high elastic strains without damaging the crystal structure of the material. A team of researchers has now succeeded in experimentally demonstrating that electron mobility in nanowires is remarkably enhanced when the shell places the wire core under tensile strain. |
