The story of our technology started in 2004, when the then medical director of the UK National Society for Epilepsy convinced Acurable’s co-founder Professor Esther Rodriguez-Villegas to use her unique knowledge of low power microelectronic design to develop an apnoea monitoring technology that prevented sudden unexpected death in epilepsy, a type of epilepsy seizure that kills up to 1,000 people per year in the UK alone.
The problem was not just detecting apnoea, but doing so with a device that was very small, unobtrusive, had the ability to monitor for long periods, and was extremely accurate, since missing an apnoea could be fatal, and false alarms would discourage its use. Existing sensing modalities and signal processing algorithms did not meet these criteria. So novel sensing, hardware and software engineering techniques were devised to overcome these challenges.
With time, Esther realised that this technology could however have much wider applications, including sleep apnoea screening and the continuous remote monitoring of a variety of respiratory and cardiac conditions.
