Abstract:
An apparatus for measuring at least one selected physical condition of an animate subject, the apparatus comprising:a light source; a light receiver, said light receiver capable of receiving resultant light from said light source via said subject; and an information processor connected with at least said light receiver; said information processor receiving an indication of said resultant light from said light receiver and evaluating said indication to effect said measuring, said information processor being implemented in a unitary structure with at least one of said light source and said light detector; said unitary structure comprising a monocrystalline silicon substrate; a monocrystalline perovskite oxide material overlying at least a portion of the monocrystalline silicon substrate; an amorphous oxide material located between the monocrystalline perovskite oxide material and the monocrystalline silicon substrate; and a monocrystalline compound semiconductor material overlying at least a portion of the monocrystalline perovskite oxide material, wherein at least a portion of said information processor is formed within the monocrystalline silicon substrate and at least a portion of said light source is formed within the compound semiconductor material.
