Design and Control of a Dual‐Coil Magnetic Guidewire for Smooth and Adaptive Curvature Steering in Vascular Intervention

SmartBot, EarlyView.
Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...

Mitochondrial Membrane Permeability After Nanosecond Electromagnetic Pulsed Exposure

2018 20th International Symposium on High-Current Electronics (ISHCE), 2018
The purpose of the presented study was to reveal the possibility to induce electric pores and/or to open permeability transition pore in the mitochondria of normal and tumor cells after nanosecond pulsed electromagnetic exposure. Cell suspensions were exposed to two type of pulses: 10GHz microwave pulses with duration of 100 ns and 1.0 GHz RF pulses ...

Electromagnetic Characterization of Hydraulic Fracture Shape and Permeability

Proceedings, 2015
Our numerical proof-of-concept studies demonstrate that surface electric field measurements can provide sensitivity to both the geometric distribution of injected conductive fluids and or conductively enhanced proppant as well as sensitivity to the created hydraulic permeability of the fracture zone.
