Wearable Wireless Multisensor Health Monitor with Head Photoplethysmograph

摘要

Ambulatory monitoring of human health is provided by a multi-component multi-sensor wireless wearable biosignal acquisition system comprising a torso device and a peripheral device communicating wirelessly, and a mobile phone for receiving collected data and uploading it over cellular network or WiFi to a remote computer for multivariate analysis. Biosignals include EKG and PPG, from which a determination of pulse transit time can be made.

主权项

1. A system for monitoring human health comprising:
a wearable torso device disposed to continuously measure at least an electrocardiographic signal from at least two electrodes; a head-worn device in wireless connectivity with said torso device, having at least one light source disposed to illuminate the capillary bed below the skin at a location on the head and having a light sensitive element for quantitatively measuring light from said light source that has passed through the capillary bed, thereby providing a photoplethysmographic signal that is communicated to the torso device wirelessly; said torso device and said head-worn device having a mechanism implemented in software for synchronizing the electrocardiographic signal with the photoplethysmographic signal for an accurate determination of a pulse transit time.
