3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

open access: yesAdvanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Staggered-SAR: A New Concept for High-Resolution Wide-Swath Imaging [PDF]

open access: yes, 2012
Synthetic aperture radar (SAR) is the ideal sensor for the systematic observation of dynamic processes on the Earth’s surface. However, current SAR systems are limited, in that a wider coverage can only be achieved at the expense of a degraded azimuth ...

Waveform design of radar coincidence imaging radiation field based on image entropy

open access: yesElectronics Letters
Radar coincidence imaging (RCI) is a high‐resolution radar imaging mode which constructs a temporal spatial stochastic radiation field (TSSRF) and uses the correlation between reference signal and echoes for imaging. The correlation between the reference
