Abstract

The structure and pigment of silicone in implantable optical sensors are critical design parameters affecting specificity, depth of light penetration, and invasiveness, volume and power consumption of the sensor. This study investigates how silicone pigment and embedded scattering agents affect sensor crosstalk and superficial tissue scattering to guide the design of silicone housings for implantable optical sensors based on their specific application. Preliminary results suggest that the magnitude of superficial tissue scattering is proportional to the principal wavelength reflected by sensor pigment. Pigment can thus be selected based on each application’s requirement for depth of penetration.
