Pre listening the-heartbeat-of-our-world

  1. 1. Listening to the heartbeat of our world PhD Candidate: Kuo Li School of Civil Engineering and Built Environment, Faculty of Science and Engineering, Queensland University of Technology
  2. 2. Listening to the heartbeat of our world It is important to monitoring a person's heartbeat. So is to monitoring other stuff, i.e. airplanes, bridges, skyscrapers, etc . They have resonant frequencies that is similar as living creatures’ heartbeat. Can we make all of these monitoring simpler by using just one wire? The answer is: Very Possible! With our recently developed fiber Bragg grating accelerometer, which reduces the size and keep the sensitivity, I expect it would happen in the next 10 years. By that time, we could listen to the heartbeats of those important stuff.
  3. 3. Resonant frequency: at equilibrium FixedFixed y at time t x FBG L x-z yz x FBG
