This biological phenomenon complex was described in 2009 by Professors Peter fratzl (Institute Max Planck ) and Friedrich Barth (University of Vienna). http://enjoycoloring.com/dragon-ball-z/10003/ Korean scientists have relied on the work to recreate a mechanical version of this organ, they present in their paper published in the journal Nature .
The sound sensor developed by the team at the Korean National University has been successfully tested for speech recognition in a noisy environment, detect each note of a piece of music and take the heart rate of a person. © D.Kang, M.Choi, Nature
Three to five years for a marketable version of
The sensor consists of a layer of Platinum 20 nanometers thick deposited on a polymer viscoelastic. The platinum layer is cut parallel to mimic the cracks so that it can deform and stretch under the effect of vibration and sound waves. http://enjoycoloring.com/toy-story/10154/ An electric current is sent to the platinum section. When the latter is inert, the cracks are closed and current flows on the whole surface. Once a small vibration occurs, the cracks open, creating a disturbance of the conductance . It is these changes that we measure.
