Working closely with our shareholder partner, Gas Sensing Solutions, we have developed an innovative, low-cost, low-power sensor to accurately measure CO2 in normal tidal breathing. Our sensors are based on advanced III-V LED technology and use an emitter detector pair refined to work in the technically challenging 4.3µm light frequency. By using advanced epitaxially-grown semiconductor technology and simplifying the optical path we have avoided the use of costly beam splitters and rotating filters.
Developed to be more accurate, stable and sensitive than earlier generation CO2 sensors, CRiL’s CO2 sensor platform is also the fastest sensor available. It delivers unrivalled accuracy throughout the range of respired CO2, including at low CO2 levels. Our sensor has been designed and configured specifically to capture the user’s tidal breathing waveform. Variants of this sensor will be used in both the personal respiratory monitors and the advanced diagnostic devices. Whilst detailed respiratory information can be provided to the medical professional, in all of our N-Tidal devices the sensor has been combined with advanced algorithms and analytics to provide clear and easy to interpret results for the individual user.
CRiL has already filed two patent applications to protect its novel technology.
