Insplorion is a Swedish deep-tech company based in Gothenburg developing hydrogen sensors based on NanoPlasmonic Sensing (NPS).

NPS is an optical, versatile technology that detects hydrogen also in the absence of oxygen. Our sensors have palladium alloy nanostructure transducers. In the presence of hydrogen, the optical signature of the nanostructures changes, generating the sensor signal. The sensor signal is reversible and corresponds to the partial pressure of hydrogen in the sensor chip environment.
