Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Metasurface‐Enabled Helical Wavefront Fingerprint Metrology for Quantitative Retrieval of Liquid Optical Constants

Advanced Science, EarlyView.
A metasurface‐enabled helical wavefront fingerprint (MHWF) paradigm is proposed for quantitative and specific retrieval of a liquid medium's refractive index and extinction coefficient. The liquid's complex dielectric response governs the wavefront evolution of the metasurface‐generated focused vortex beam, forming a distinctive three‐dimensional ...

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Hydraulic Pressure‐Programmed Molecular Transport in Tough Hydrogels

Advanced Science, EarlyView.
Hydraulic pressure is introduced as a programmable parameter for regulating molecular transport in tough hydrogel membranes. Reversing the pressure direction accelerates or slows transport, tuning characteristic transport times over a 65‐fold range while achieving molecular separation and controlled delivery.

SynNotch Receptors for Visualizing Immunoreceptor Force Transmission and Downstream Signaling In Vivo

Advanced Science, EarlyView.
A mechanically activated SynNotch reporter platform enables detection of force transmission through receptors as they mediate immune cell interactions. Targeting CD40 on B cells and TCR on T cells records force‐induced reporter activation across 2D coculture, 3D organoid, and implanted in mice, which also reveal force‐amplification of immune receptor ...
