Scientists Noticed Ferroelectricity In Mammals, Common In TVs & Computer Memory

 The heart’s inner workings are mysterious, perhaps even more so with a new finding. Engineers at the University of Washington have discovered an electrical property in arteries not seen before in mammalian tissues.
The researchers found that the wall of the aorta, the largest blood vessel carrying blood from the heart, exhibits ferroelectricity, a response to an electric field known to exist in inorganic and synthetic materials. The findings are being published in an upcoming issue of the journal “Physical Review Letters”.
“The result is exciting for scientific reasons, but it could also have biomedical implications”, said lead author Jiangyu Li, a UW associate professor of mechanical engineering.
A ferroelectric material is an electrically polar molecule with one side positively charged and the other negatively charged, whose polarity can be reversed by applying an electrical field. Ferroelectricity is common in synthetic materials and used for displays, TVs, computer memory , and sensors.
he team is investigating the interactions between ferroelectricity and charged glucose molecules, in hopes of better understanding sugar’s effect on the mechanical properties of the aortic walls.
