Adaptative two-phase thermal circulation system for complex-shaped electronic device cooling.

Thermal management using a vapor-liquid two-phase circulation system is challenging in compact and complex-shaped electronic devices. In this study, we design and fabricate a heat pipe that can adapt to various shapes, regardless of space constraints. The heat pipe is capable of bending or twisting in three dimensions, making it suitable for electronic devices of arbitrary shapes.

Study on Forming Mechanism of the Recast Layer on the Workpiece Surface during Micro EDM.

In comparison to conventional EDM, micro EDM distinguishes itself through its brief discharge duration, narrow discharge channel radius, and concentrated energy density. However, there remains a paucity of comprehensive research on the surface formation characteristics in this domain. This paper delves into the formation mechanism of the recast layer in micro EDM workpieces, scrutinizing the primary factors that influence the formation process and the morphological attributes of the recast layer.

Magnetic field assisted laser fabrication and electrical characterizations of metal dry Biolectrode with surface microstructures.

Magnetic field assisted laser fabrication is proposed to process metal dry bioelectrode with surface microstructures. The effects of magnetic flux density on the geometrical dimension of surface microstructures of bioelectrode is investigated. The electrode-skin contact impedance is then studied using the two-electrode measurement method.
