Broad spectrum breath testing - hand-held medical diagnostics
They is also mention of olfactory signal processing (smell) suggesting use for devices that can identify the presence of molecules in air. Such "bloodhound" devices could be deployed for advanced medical diagnostics that could identify an extraordinary range of diseases and medical conditions simply through sampling a person's breath.
The impact on the medical diagnostics industry could be, er - breath taking.
On 23 July 2020 the company announced that Nobel Prize Laureate Professor Barry Marshall has joined Brainchip's scientific advisory board. Prof. Marshall was awarded the Nobel Prize in 2005 for his pioneering work in the discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease. The gold-standard test for Helicobacter pylori involves analysing a person's breath.
Detection of endogenous (originating from within a person, animal or organism) volatile organic compounds resulting from various disease states has been one of the primary diagnostic tools used by physicians since the days of Hippocrates.
With the advent of blood testing, biopsies, X-rays, and CT scans the use of breath to detect medical problems fell out of clinical practice.The modern era of breath testing commenced in 1971, when Nobel Prize winner Linus Pauling demonstrated that human breath is complex, containing well over 200 different volatile organic compounds.
Certainly works for Police breath testing to measure blood alcohol levels.
Sensing and quantifying the presence of organic compounds (and other molecules) using electronic olfactory sensors feeding into an AI processing system could be the basis for low-cost immediate medical diagnostics assisting clinicians to more quickly identify conditions warranting further investigation and providing earlier indications long before symptoms are apparent.
Semico published an article in their March, 2021 IPI Newsletter detailing a press release between NaNose (Nano Artificial Nose) Medical and BrainChip announcing a new system for electronic breath diagnosis of COVID-19. This system used an artificially intelligent nano-array based on molecularly modified gold nano particles and a random network of single-walled carbon nanotubes paired with the Akida neuromorphic AI processor from BrainChip.
Since then, NaNose has broadened the spectrum of diseases that can be detected and is working toward commercial release...
