During the spiral inductor design process, designers and design automation tools require efficient modeling techniques for initial design space exploration in order to quickly pinpoint appropriate inductor geometries. In this paper, we introduce a new frequency-dependent model that utilizes closed-form expressions to quickly characterize square spiral(More)
We have designed, fabricated and characterized large displacement distributed-force polymer actuators driven only by the surface tension of water. The devices were inspired by the hygroscopic spore dispersal mechanism in fern sporangia. Microdevices were fabricated through a single mask process using a commercial photo-patternable silicone polymer to mimic(More)
Inspired by water transport in plants, we present a synthetic, microfabricated " leaf " that can scavenge electrical power from evaporative flow. Evaporation at the surface of the device produces flows with velocities up to 1.5 cm/s within etched microchannels. Gas-liquid interfaces within the channels move across an embedded capacitor at this velocity,(More)
