What is smart glass/film?
Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.
The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic.
In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.

No, the internal PDLC layer is plastic and does not conduct electricity, since it is electrically insulated. Rather, it behaves more like a capacitor, where the applied signal alternates between positive and negative voltages at the plates of the capacitor, causing an alternating electric field throughout the PDLC dielectric, which is what aligns the liquid crystals with the frequency of the signal (normally 50 Hz or 60 Hz).
Transportation
Architectural (residential and commercial)
Interior design
Retail advertising
Healthcare (i.e. hospitals and clinics, since the PDLC smart glass can replace unhygienic curtains and blinds which often carry microbes and germs, and this also improves air quality)
Banking, thanks to the privacy afforded to ATMs and as internal partitions
Hospitality, especially bathrooms, since more natural light can penetrate interior spaces lacking windows to the outside world.
Yes, smart glass/film is available in all irregular shapes as you want, including curved glass.
Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.
When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.
