Technology - How does it work?
Semiconductor-Photocatalytic Hybrid (SPH) chemical sensor technology was invented by N5’s science team and has been under development for over 10 years. SPH architecture combines high-performance semiconductor transducers with nanoengineered photocatalytic functional layers. With such nanoengineered high-density sensor arrays on a chip, we can utilize machine learning algorithms to provide rich data about any environment.
