Sensorebene
Sensorebene is a term used to describe the functional layer within a multilayer sensor architecture that directly interacts with the measurand. This layer, distinct from the substrate, interconnects, and protective coatings, serves as the interface where the physical, chemical, or biological quantity is converted into a transducer signal that the rest of the device can process.
Materials used in sensorebene include inorganic metal oxides (such as SnO2, ZnO), carbon-based materials (graphene, carbon
The sensorebene normally implements one or more transduction mechanisms, such as changes in electrical resistance or
Applications of the sensorebene concept span chemical and biological sensing, environmental monitoring, medical diagnostics, and consumer
Fabrication typically involves thin-film deposition, spin coating, or lithographic patterning, often paired with surface functionalization techniques
Challenges include achieving high selectivity in complex environments, long-term stability, and reproducible manufacturing. Ongoing research explores
