2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Sub‐1 ms Optoelectronic Synapse Based on {ZnCdO/ZnO} Multilayer Structure for High‐Speed Neuromorphic Vision Systems

Advanced Functional Materials, EarlyView.
Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

A New Strategy for Creating Quantum Light Emitters Via Post‐Growth Hydrogen‐Ion Irradiation of III‐V Nanowires

Advanced Functional Materials, EarlyView.
A post‐growth method is demonstrated to realize energy‐tunable quantum emitters in GaAs/GaAsN/GaAs core–multishell nanowires on a Si substrate. By combining the N‐induced bandgap reduction with H‐ion irradiation, the GaAsN potential landscape is engineered, enabling isolated, narrow emission lines that function as single‐photon sources with g(2)(0) ∼ 0.
