LightShield: Electrochromatic Windshield
- Program: Chemical and Biomolecular Engineering
- Course: EN.540.314 ChemBE Product Design
- Year: 2026
Project Description:
LightShield introduces an electrochromatic approach to windshield tinting, making use of a liquid crystal layer to transition between tinted and untinted states. The alignment of the liquid crystals controls the light transmission through the layer, and can be modulated through an electric field. Our team proposes this solution for windshield glare reduction, improving upon previous methods in metrics of transition speed and ease of use.
