Instead, the monitor works via a small sensor placed just below the surface of your skin. You need to place the accompanying screen monitor above the system to get your glucose reading.

Abstract: In this work, a plastic optical fiber (POF) based surface plasmon resonance (SPR) sensor is proposed and demonstrated for simultaneous measurement of refractive index (RI) and liquid level.
