Smart glass, also known as switchable glass or dynamic glass, is an advanced glass technology that changes its light transmission properties when voltage, light, or heat is applied. This innovative material can transition from transparent to translucent or opaque states on demand, offering privacy, light control, and energy efficiency benefits. Types include electrochromic, thermochromic, and suspended particle devices (SPD). Smart glass is increasingly used in modern architecture, vehicle sunroofs, skylights, and interior partitions. Its ability to reduce heating and cooling costs by regulating solar gain makes it an environmentally friendly building material gaining popularity in sustainable design.
