Fuente: Wipo "Sensorization" A sensor device comprises: a plurality of sensors configured to be affected by a measurand; a waveguide 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, each being individually controllable and configured to control a resonance wavelength of the sensor associated with the control element; the sensor device being configured to, for read-out of measurement from a selected sensor, 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 uniquely aligned with the selected interrogation wavelength for reading out the measurand measured by the selected sensor.
