Invisible fly screen / Window

Invisible fly screen

The Invisible Fly Screen uses solar power to deter insects with ultrasonic sound. The Invisible Fly Screen is just that – more specifically, it is an ultrasonic insect deterrent that activates when a window is opened. The product incorporates solar and electronic components as well as the window frame and glazing.The system uses a DSSC battery (a dye-sensitised solar cell) and FTO (fluorine doped tin oxide) glass to collect solar heat. Electrical power is then stored in a mini battery, which powers the ultrasonic speakers. The speakers are activated automatically when the window is opened.
