An anti-sticking patterned metallic stamp for imprinting has been successfully fabricated in this study. Firstly, the amorphous phase transformation films of Ge2Sb2Te5 (GST) were deposited on the cleaned silicon substrates by DC sputtering system. The as-deposited GST film was then irradiated with femtosecond laser pulse through a photomask to induce the crystalline mark on the surface. The patterns...
The present paper proposes a method to directly measure pressure distribution in a microchannel. A polyvinylidene fluoride (PVDF) piezoelectric film was packaged on the inside wall of a microchannel and connected to an external signal filtering amplifier to the oscilloscope to observe the voltage response when the flow through the microchannel and then the voltage response of the PVDF film converted...
