Small core FBG-based temperature compensated ‘smart’ contact lens for effective intraocular pressure measurement

Small core FBG-based temperature compensated ‘smart’ contact lens for effective intraocular pressure measurement

In this work, a small core, Fibre Bragg Grating (FBG)-based smart contact lens for intraocular pressure (IOP) measurement has been demonstrated. Further, an integral temperature compensation mechanism has been developed and included in the sensor design, allowing it to offer good long-term measureme...
