Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.

The tensions of securing cyberspace: The Internet, state power and The National Strategy to Secure Cyberspace

First Monday, 2004
The National Strategy to Secure Cyberspace exposes a growing tension between the nature of the Internet and the regulatory powers of the traditional nation–state. The National Strategy declares, with all the strength and authority of the United States government, the desire to secure a space many consider, by its very nature, chaotic and beyond the ...

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...
