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 ...

Understanding Inhomogeneous Crystallization Dynamics of Phase‐Change Materials in the Vicinity of Metallic Nanoantennas

Advanced Optical Materials, EarlyView.
Metallic dimer antennas on top of the phase‐change material Ge3Sb2Te6 are addressed with laser pulses, resulting in inhomogeneous crystallization. A self‐consistent multiphysics model is employed to simulate the crystallization and to understand the resulting shift of the antenna resonance.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Method for identifying parameters of submersible induction motors of electrical submersible pump units for oil production

Известия Томского политехнического университета: Инжиниринг георесурсов, 2017
Relevance of the research is caused by fact that 80 % of oil in the Russian Federation is extracted using electrical submersible pump units and this index is growing, but specific ratio of wells with electrical submersible pump in the general fund has not almost changed and it is about 34 %. It necessary to note that maintenance of optimal operation of
