Magnetically Controlled Reversible Photomagnetic Nanoactuators for Dynamic Contrast Enhancement in Optical Coherence Tomography

Advanced Materials, EarlyView.
Photomagnetic nanoactuators with ≈90% scattering efficiency in the second near‐infrared window are demonstrated to exhibit magnetic field‐controlled modulation of optical scattering and optical coherence tomography signals. These nanoactuators are reversibly assembled and disassembled under the external magnetic field modulation, enabling enhanced ...

Stretchable, Multiplexed, and Bimodal Sensing Electronic Armor for Colonoscopic Continuum Robot Enhanced by Triboelectric Artificial Synapse

Advanced Materials, EarlyView.
Colonoscopic continuum robots lack sensing, endangering intestinal tissue. An ideal sensing array is hard to integrate. This work introduces a 3D crosslinked stretchable E‐armor with full‐coverage and multiplexing. It has bimodal sensing, forms a triboelectric synapse, uses CNN‐LSTM, and has a hydrogel and innovative triboelectric materials.
