Inside Beagle™, King’s Phase Technologies has developed a gas sensor module capable of detecting organic compounds at concentrations down to parts per billion. This sensitivity comes from the sensor’s proprietary metal oxide surface coating, creating a surface with unparalleled porosity and high sensitivity. Our semiconductor ketone gas sensor provides ketone sensing capability in the range of part per billion range which is over 1000X more sensitive. This high sensitivity allows our sensor to be used in personal fat metabolism tracking applications, currently primarily targeted towards the fitness and wellness market.
