Flying Drone Base Stations for Macro Hotspots

IEEE Access, 2018
We study a scenario where multiple drone-mounted base stations cruise freely over a macro hotspot to serve mobile users on the ground. The drone base stations move constantly and update their moving directions following our proposed mobility control ...

Laser‐Induced Local De‐Doping in Organic Semiconductors

Advanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Highly Conductive and Transparent Coatings via Low‐Temperature Hydroiodic Acid Vapor Treatment of Oxo‐Graphene Thin Films

Advanced Materials Technologies, EarlyView.
The double self‐assembly (DSA) method applied to oxo‐graphene (oxo‐G) flakes followed by hydroiodic acid (HI) vapor treatment and low‐temperature annealing yields highly conductive, optically transparent thin films with the potential for applications in electronic and optoelectronic devices.

Contact‐Architecture‐Dependent Mixed Ionic‐Electronic Transport in Solution‐Grown MAPbBr3 Microwire Photodetectors

Advanced Optical Materials, EarlyView.
MAPbBr3 microwire photodetectors reveal a strong architecture dependence of mixed ionic–electronic phototransport. A single‐gap device exhibits pronounced illumination‐history‐dependent transients governed by trap‐assisted injection and ionic polarization, whereas a multi‐gap configuration averages local interfacial effects and yields stable ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
