Digital sensor with reference cantilever for converting chemical and/or biochemical information

A sensor for converting at least one of chemical and biochemical information about an analyte in a sample into an electrical signal, the sensor comprising

• a test cantilever having a base and a deformable part on which a receptor layer for selective reception of the analyte is applied, where a passive test transducer is arranged on the base and an active test transducer is arranged on the deformable part;
• a reference cantilever having a base and a deformable part on which a reference layer for selective non-reception of the analyte is applied, where a passive reference transducer is arranged on the base and an active reference transducer is arranged on the deformable part,
• wherein the active and passive reference transducers and the active and passive test transducers are configured to output an electrical signal corresponding to at least one of an incidence, a concentration and an amount of the analyte in the sample.
