Claim 12:
13. A device, comprising:
a band comprising a shape, size, and flexibility designed for attaching the band to a body part of a user;
a light source embedded in the band, wherein:
the light source emits light to interrogate the body part, the light comprising a constituent wavelength that provides an indication of a feature of the body part;
the light source is positioned in the band to emit, as the user wears the band, the light towards the body part;

an optical sensor integrated into the band and positioned in the band to receive the constituent wavelength, wherein the optical sensor is positioned in the band to receive, as the user wears the band, the constituent wavelength through the body part;
an optical filter; and
a glass substrate integrated into the band and oriented in the band to receive the light through the body part as the user wears the band, the glass substrate comprising:
a glass substrate; and
carbon nanotubes coupled to the glass substrate forming a grid of carbon nanotubes.
