Femtosecond Laser-Written Invisible Sensors in Architectural Glass and Their Impact on Strength

Invisible sensors realized in the bulk of glass using femtosecond laser direct-writing

As structural glass takes on load-bearing roles, real-time monitoring becomes increasingly important. We explore how invisible optical sensors, embedded using femtosecond laser technology in the glass, can enable strain and temperature monitoring without affecting strength or aesthetics.
