Yes, smart glass/film is available in all irregular shapes as you want, including curved glass.
Switchable Toughened Glass
Switchable Laminated Glass
Switchable Double-Glazing
Switchable Window Film
A flexible polymer-based film (typically PDLC: Polymer Dispersed Liquid Crystal) with an adhesive layer on one side. It is applied directly to existing glass surfaces like a sticker. A laminated glass unit where PDLC film is permanently sandwiched between two layers of glass using EVA or PVB interlayers under high pressure/temperature. This creates a solid, structural glazing product. • Optical Clarity: • Energy Efficiency: • Durability: • Safety: • Film: Ideal for retrofitting offices, shower doors, storefronts, or rental properties. • Glass: Suited for high-end architectural projects (facades, security rooms, partitions), automotive sunroofs, and aviation. Choose self-adhesive smart film for cost-effective, non-invasive upgrades to existing glass. Opt for smart glass in new builds or high-traffic areas demanding durability and safety. Both deliver dynamic privacy/energy savings but cater to different project scales and budgets.1. What is self-adhesive smart film and smart glass

2. Installation & Application
Feature
Self-Adhesive Smart Film
Smart Glass
Installation
Peel-and-stick onto existing glass; DIY-friendly.
Requires professional glazing; replaces entire glass unit.
Best For
Retrofitting existing windows/glass partitions.
New constructions or full renovations.
Complexity
Some skill is needed:
1. How to install the film;
2. How to deal with the edge sealant;
3. How to hide the wire.
Install the glass as the normal glass except for considering how to hide the wire.
How to make smart glass?
3. Functionality & Performance
Both switch between transparent (ON) and opaque (OFF) via electricity. Smart Glass often has higher clarity due to glass encapsulation.
Identical function: Blocks ~99% UV rays and reduces heat gain.
Power consumption is low (~5W/m²/hour).
Smart Glass is more robust (scratch resistant, impact-resistant, safety-glass properties, longer life time). Film is vulnerable to peeling/scratches comparing with smart glass.
Smart glass remains secure after breaking. Film lacks structural security but can prevent glass from shattering.

Conclusion
The following information is from homeadvisor.com.
Smart Glass Cost
Smart glass costs $25 to $150 per square foot. Glass with film pre-installed is $50 to $150 per square foot, compared to $25 to $50 per square foot for the film alone. Price depends on the total square footage, with single units running up to $50 per square foot more than you’d pay to install several.
Smart glass makes it easy to change the look of your windows in an instant. You can make them completely opaque for privacy or add tinting to shade a home and cut your energy consumption. There are a few different types with unique benefits, so you’ll need to choose the one that’s right for you. Keep these cost factors in mind as you browse.
Average Smart Glass Price
| Average Cost | $100 Per Square Foot |
| High Cost | $150 Per Square Foot |
| Low Cost | $25 Per Square Foot |
Smart Glass Cost Per Square Foot
Smart glass costs $50 to $150 per square foot. Installers usually set rates by the project, offering a lower price per square foot if you replace several windows. One piece runs $125 to $150 per square foot, compared to $50 to $100 per square foot for 100 or more square feet. The cost to install a window with standard glass is $15 to $30 per square foot.
Smart Glass Pricing by Type
Smart glass prices are $50 to $150 per square foot, depending on the total square footage and type:
PDLC: Privacy, frosted, tinting
SPD: Tinting in an instant
Electrochromic: Gradual tinting to a set level
PDLC
PDLC glass tends to be the most expensive option. It offers privacy at the touch of a button, making it ideal for indoor and outdoor applications. This technology is the only type that turns completely opaque, which means you can use it for bathrooms, showers, private offices and more. You can also turn it into a television projector.
PDLC has crystals that are both liquid and solid, similar to what you’d get in an LCD television or monitor. It has a lot of names, including:
Electric privacy glass
LCD glass
Electric frosted glass
The crystals are inactive when turned off, which makes the glass appear frosted or dark. Once you turn it on, the window is completely clear or dimmable.
SPD
SPD glass is the middle-of-the road cost option, with pricing a little lower than PDLC. This type allows you to select the level of tinting from minimally shading to full darkness, although it can’t provide complete privacy. Its heat-blocking features make it a great choice for exterior windows. You can also use it for any interior room that needs additional darkness in daytime, like a home theater or child’s bedroom.
SPD suspends particles in a liquid. When you turn on the device, it brings those particles in line and allows you to the control the level of tinting. Like PDLC, these windows are dimmable.
Electrochromic
Electrochromic glass is the cheapest option. This type allows you to change the tinting over the course of a few minutes. It uses ions to force particles to the inside or outside of the window, making the material clear or tinted. Those particles stay in position until you use the control to move them again.
Electrochromic glass is similar to photochromic or thermochromic tinting, but it’s important to understand the difference. Photochromic and thermochromic products, like Transitions eyeglass lenses, tint based on light or heat. They don’t require energy to change, but you can’t control them. Electrochromic options use energy comparable to a single LED lightbulb, and make it easy to change whenever you want.
Switchable Glass Prices vs. Smart Window Film
Switchable glass, which may refer to PDLC, SPD or electrochromic products, costs $50 to $150 per square foot and includes all materials and installation. If you want to buy smart film that you can have a pro apply to your existing windows, you’ll pay $25 to $50 per square foot.

PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.
Smart glass/film consumes less than 5W/sqm.
