Fuente: Wipo "Sensorization" A sensor device (100) comprises: a plurality of sensors (110; 210; 310) configured to be affected by a measurand; a waveguide (120; 220; 320) associated with a group of sensors and configured to receive an optical interrogation signal comprising at least one interrogation wavelength; a plurality of control elements (130; 230; 330), each being individually controllable and configured to control a resonance wavelength of the sensor (110; 210; 310) associated with the control element (130; 230; 330); the sensor device (100) being configured to, for read-out of measurement from a selected sensor (110; 210; 310), tune its resonance wavelength to be aligned with a selected interrogation wavelength; the group of sensors being configured to be controlled for arranging, at a single read-out time point, the selected sensor (110; 210; 310) uniquely aligned with the selected interrogation wavelength for reading out the measurand measured by the selected sensor (110; 210; 310).
