Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation
Advanced Materials Technologies, EarlyView.Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Rational Inflationary Bubbles [PDF]
This paper analyzes the possible inception of rational inflationary bubbles under the assumption that the empirically relevant environment precludes the existence of rational deflationary bubbles. The analysis shows that if a rational inflationary bubble

Advanced Materials Technologies, EarlyView.Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

Advanced Optical Materials, EarlyView.Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

Impact of Plasma Bubbles on OTHR Shortwave Propagation in Different Backgrounds
Remote SensingPlasma bubbles represent notable ionospheric irregularities primarily observed in low latitudes, characterized by plasma depletions exhibiting large spatial scales, which can make a significant impact on the propagation of OTHR (over-the-horizon radar ...

Microsatellite to study plasma bubbles in ionosphere [PDF]
Eos, Transactions American Geophysical Union, 2007 An experimental instrument called the Flat Plasma Spectrometer, which was launched onboard a U.S. Air Force Academy microsatellite on 8 March, will study depletions in the ionosphere known as plasma bubbles that can disrupt satellite communications. The six‐month mission will demonstrate the effectiveness of the new instrument, which has been reduced ...

Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol
Advanced Robotics Research, EarlyView.Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

Instability of bubbles in the quark-gluon plasma
Physics Letters B, 1992 Abstract The small surface tension of vacuum bubbles in the quark-gluon plasma, along with a negative curvature tension, implies that the uniform plasma is unstable against the formation of such bubbles. We show that spherical bubbles are in turn unstable against the growth of irregularities.
