One feature on the beleaguered Boeing 787 Dreamliner is its electrochromic dimming system that lets passengers make windows on the aircraft more or less opaque at the touch of a button.
Japan’s National Institute of Advanced Industrial Science and Technology (AIST) says that while these smart windows can take about 30 seconds to change, it has a new stick-on window film that can go from reflective to see-through in only 5 seconds.
The switchable mirror device can change states when a low voltage is applied.
The tech can be used to produce low-cost, large-scale smart windows, according to AIST. In contrast to some smart windows, the sheet reflects light instead of absorbing it, preventing the glass from heating up.
Since it reduces incoming heat, the sheet could help keep buildings and vehicles cool in summer, reducing the need for air condi… [Read more]
