Novel technique for sleep apnea monitoring

Sleep Apnea is a well-documented and chronic problem that can result in various life threatening disorders. Detecting and diagnosing sleep apnea requires a long duration sleep study that makes use of various sensor based monitors. The need for long duration sleep studies at a special care provider facility and lack of simple portable monitors result in many undiagnosed cases. In this paper, we have proposed and implemented a low cost, self-powered, sleep apnea monitor that detects apnea episodes using simple body mounted sensors. The entire system is powered by RF energy that is fetched from the ambient environment.
