Abstract: Embodiments of the present disclosure may include an implantable device (100) for in vivo measurement of metabolites, including a laser diode (110) or an IR diode (120) or optical waveguide as an external (outside body) light source with a laser diode (110) or an IR diode (120) for Raman spectroscopy unit (140). Embodiments may also include an optical filter (130) that filters the scattered light. Embodiments may also include a Raman spectroscopy unit (140) for detecting the metabolic profile of a subject. Embodiments may also include a Fabry-Pérot interferometer (150) with a spherical mirror, functioning as an etalon, for refining the detection of Raman scattering signals. Embodiments may also include a CMOS sensor (160) for capturing the refined Raman scattering signals. Embodiments may also include a piezo element (170a) or MEMS actuator (170b) for actuating the Fabry-Pérot interferometer (150). Embodiments may also include MCU (180) as a controller and a processing unit.
