New opportunities for wearablehealth and wellness
continuous monitoring devices
Zillions of gadgets to monitor various physiological and environmental signalsTypically proprietary data transmission protocols Typically capture on-board and off-line processing of the data after downloading to a PCVery difficult if not impossible to combine signals from different gadgetsLack of real-time on-board processing of the information to deliver value to the user
Continuous monitoring and understanding of multiple physiological and environmental signalsFinding correlations between lifestyle and wellness/healthIdentifying trends and deviations from those trendsDeveloping new interesting and fun applicationsEmpowering users

Real-time, wearable physiological monitoring system on a mobile phonePhysiological sensors wirelessly connected via Bluetooth to a mobile phoneContinuous recording of blood oximetry, heart-rate and plethysmographic signalReal-time analysis and presentation of physiological data to the userUsage scenario: Sleep monitoring and automatic sleep apnea detection

Underdiagnosed but common conditionAffects children and adults4% in men and 2% in women (higher for elderly)Untreated causes $3.4 billion of medical costs40 million undiagnosed Americans
Periods of interrupted breathing (apnea) and periods of reduced breathing (hypoapnea)Leads to
Hypoxia, asphyxia and awakeningsIncreased heart-rate, high blood pressureExtreme fatigue, poor concentrationCompromised immune systemCardio/cerebrovascular problems
8
Nocturnal Polysomnography (PSG)In sleep center for 1-2 nightsContinuous, simultaneous multi-channel measurements of 8 physiological signals Very expensive, cumbersome, time consuming, just one sample and subject to manual scoring and human error
Pulse oximetry Useful as screening toolOne simple, light-weight sensor on finger, toe or earlobe
