The simple window has undergone yet another metamorphosis.
Windows are a pretty important part of a building design, usually they are one of the most susceptible points of entry or exit for heat, noise, sound and well unwanted intruders. Researchers at the Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, Germany have developed a window that vibrates to cancel out unwanted noises. In a similar idea as noise canceling headphones, ceramic piezoelectric patches act as sensors and vibration generators to detect, then respond to cancel out the noise.
This seems to be a great advancement on the use of double or even triple thick glass to dampen sounds, perhaps this can be embedded with a solar power generating material to make best use of available sunshine too.
