Tracking your Tax Dollars: What dancing robots and puppets have to do with spending on the light rail. | KSTP-TV

Inspired by fireflies, researchers create insect-scale robots that can emit light when they fly, which enables motion tracking and communication. To fabricate a glowing actuator, the team incorporated electroluminescent zinc sulphate particles into the elastomer but had to overcome several challenges along the way. First, the researchers had to create an electrode that would not block light. They built it using highly transparent carbon nanotubes, which are only a few nanometers thick and enable
