Commercial-printed-circuitry-compatible Self-superhydrophobic Antennas Based on Laser Direct Writing

Spline Based Geometry for Printed Monopole Antennas

Laser scanner for direct writing lithography.

A laser scanner and a stepping xy stage have been developed for direct writing lithography in the micron and the submicron range. System design is described and examples of exposed photoresist with a structure size of 1 microm are presented.

Ultra-Wideband Printed Antennas Design

On February 14, 2002, the Federal Communications Commission (FCC) of the United States adopted the First Report and Order that permitted the commercial operation of ultra wideband (UWB) technology (FCC, 2002). The FCC allocated a bandwidth of 7.5GHz, i.e. from 3.1GHz to 10.6GHz, to unlicensed use for UWB applications. Ultra Wideband is defined as any communication technology that occupies great...

3D printed microfluidic circuitry via multijet-based additive manufacturing.

The miniaturization of integrated fluidic processors affords extensive benefits for chemical and biological fields, yet traditional, monolithic methods of microfabrication present numerous obstacles for the scaling of fluidic operators. Recently, researchers have investigated the use of additive manufacturing or "three-dimensional (3D) printing" technologies - predominantly stereolithography - ...

In‐Gel Direct Laser Writing for 3D‐Designed Hydrogel Composites That Undergo Complex Self‐Shaping

Self-shaping and actuating materials inspired by biological system have enormous potential for biosensor, microrobotics, and optics. However, the control of 3D-complex microactuation is still challenging due to the difficulty in design of nonuniform internal stress of micro/nanostructures. Here, we develop in-gel direct laser writing (in-gel DLW) procedure offering a high resolution inscription...
