Amy discovered some good settings for getting 3D printed materials to stick to spandex. We can print flat, thin structures and have them control how the fabric bends and folds. We can also use the fabric’s tension to warp them into 3D shapes. This concept has a lot in common with our microscale pop-up structures. …

Four independent study students finished projects in Spring 2015. (A) Tayce Lassiter tested a differential impedance circuit on paper microfluidics, and also built a metal case to keep out noise.(B) Juan Espinosa, our GE Edison student, carried on an embedded systems project on a self-filling water pitcher for the fridge. He also motivated the ECE …
Flows can be driven using metallized surfaces in an electric field. This research area is called “induced charge electrokinetics.” It originated in the world of metal colloids, saw some applications in microfluidics in the 90s, and has seen more intense research over the past 10 years. This paper is a good introduction to flows around …
FirstBuild is helping make a molded plastic diffuser for the Trilife cellular computing project. The MATLAB file (rainbow colored inset) got CNC milled into a Modulan tool for vacuum forming thanks to Jeremy Turner and Randy Reeves at First Build. We are looking at PETG for the plastic that will be formed over this mold, because …
We continue working with the Welch group at U of L on tracking appliance usage in homes and offices. The goal is for individuals to track their own energy consumption with mobile sensors. Here’s Dr. Welch’s Ph.D. student Anand Kulkarni running an appliance near a copper plane antenna to pick up its electromagnetic field (EMF) signature. …
