Presentation Transcript

  1. Vacuum Microfabrication on Live Fruit Fly Anegal J. Shum and Babak A. Parviz University of Washington IEEE International Conference on MEMS, 2007

  2. Motivation • Fruit Fly: a sophisticated microsystem • Energy storage, microactuation, sensing and decision making funtions • Current state of MEMS field unable to reproduce such complexity • Interface electronic circuits with insects and control their functions • Construction of hybrid micro-flying robots

  3. Background • Model organism: Drosophila or Fruit Fly. • Widely used in developmental biology field • Life span four to six weeks: Focus on adult stage

  4. Vacuum Survival • Pressures as low as 55 mTorr durations up to 70 minutes • Fruit flies gained consciousness within an hour • Younger flies survived more than older flies! • Hungry flies survived less than fed fries! • And Female flies survived more than male flies!

  5. Patterning Process Fabrication Process

  6. Live Fruit Fly after Thermal Evaporation 100 nm thick 50 μm wide Indium patterns evaporated at 1 mTorr for 30 minutes at 30° C 30% of flies survived!
