Air Jet Spinning

Nanofiber assembly by rotary jet-spinning.

High-voltage electrical fields and low production rate limit electrospinning, the electrical charging of polymer liquids, as a means of nanofiber fabrication. Here, we show a facile method of fabrication of aligned three-dimensional nanofiber structures by utilizing high-speed, rotating polymer solution jets to extrude fibers. Termed rotary jet-spinning, fiber morphology, diameter, and web poro...

Tilted Micro Air Jet for Flow Control

In this paper, we present an interesting method to microfabricate a tilted micro air jet generator. We used the well-know deep reactive ion etching (DRIE) technique in order to realize in a silicon substrate a double side etching. For aircraft and cars, micro air jets will take an important place for fluid control. Micro air jets are characterized by their speed, frequency and tilt. Usually, th...

Air-Jet Button Effects in AR

Providing haptic cues can generate increased levels of presence in users as they interact with tangible objects. In this paper, we present button effects delivered by air-jet displays with the aim of providing click-like sensations when virtual buttons in an AR environment are pressed. We derive the profile of the haptic output by measuring the force profile of real physical buttons. To validat...
