Demonstrated is a novel method to the fabrication of microfluidic devices utilizing a dual-sensor approach. The fabrication incorporates the use of poly(methyl-methacrylate) (PMMA) and inkjet-printing techniques. PMMA, a low-cost, robust material with low dielectric loss, is ideal for sensor fabrication. In addition, inkjet-printing polymer (SU-8) as a bonding layer dramatically improves the bonding...
Flexible inkjet-printed proximity-fed patch antennas, designed for the 24-GHz Industrial, Scientific, and Medical (ISM) band, are demonstrated in this letter for the first time featuring a multilayer inkjet deposition process. Inkjet printing of antennas allows for the low-cost, noncontact, and additive fabrication of RF components onto nearly any host substrate or package. The inkjet-printing process...
It is frequently assumed that composite insulation, consisting for example, of a column of air in series with a solid dielectric, breaks down because a discharge in the weaker gaseous section acts like a thin conducting extension of the electrode. The applied voltage is conveyed by the discharge channel to the stronger medium, which breaks down provided the stress concentration is such that the intrinsic...
