Claim 22:
23. An implantable cardiac device comprising:
a lead configured for cardioversion/defibrillation, pacing, and/or sensing, wherein the lead is embedded with at least one Fiber Bragg Grating (FBG) sensor, wherein the FBG sensor is configured to receive an optical signal from a light source, interact with a transmitted spectrum of the light source over a discriminating spectral domain, and generate a reflected optical signal representative of a change in a physical signal sensed by the FBG sensor;
an interface unit coupled to the lead;
an optoelectrical coupler disposed within the interface unit, the optoelectric coupler comprising:
the light source;
a photodetector to transform a reflected optical signal into an electrical signal; and
a processor configured to:
analyze the electrical signal received from the photodetector; and
control a function of the implantable cardiac device based on the analysis.
