Development of ``liquid window'' inspired by squid skin, controlling the amount and wavelength of sunlight to halve the energy consumption of the house & cut off heat waves in midsummer
A research team at the University of Toronto has developed a ' liquid window ' that has the function of 'taking in the brightness of sunlight into the room while blocking heat'. It is said that the development of the liquid window was based on the `` ability to change the body color of squid ''.

There should be many people who have seen the appearance of `` squid that changes the color of the body '' in TV images and aquariums. There are colored cells called pigment cells in the skin of squid, and the color of the body is changed by expansion and contraction of the pigment cells. The research team focused on the ability of squid to ``control light reflection by changing the cell size'' and worked on the development of ``windows that control light by changing the structure''.
The windows developed by the research team are as follows. The window is composed of a sheet that can send liquid, and by sending liquid inside with a pump, it is possible to control the `` wavelength of light passing through the window '', and `` on a hot day, only the brightness of the sunlight is taken in, and the heat It is possible to realize an operation such as blocking the wavelength that generates
According to the research team, by controlling the wavelength of sunlight reaching the room with a liquid window, the cost required for lighting, heating, cooling, etc. can be reduced by up to 50%. In the future, the research team plans to work on ``expanding to a size that can cover the entire building,'' ``using harmless and low-cost materials,'' and ``optimizing liquid inflow using AI.''
