Abstract
A system for monitoring quantitative health data of a user, the system includes a stationary sensor device for monitoring a first set of quantitative health data of the user when the user is resting in bed; and a wearable tracker for monitoring a second set of quantitative health data of the user when the user is resting; wherein the wearable tracker is worn by the user; the first set and second set are sequential in time to obtain around-the-clock monitoring of the quantitative health data of the user.
Claims19
A system for monitoring quantitative health data of a user, the system comprising:
- a stationary sensor device for monitoring a first set of quantitative health data of the user when the user is resting in bed;
- and
- a wearable tracker for monitoring a second set of quantitative health data of the user when the user is away from bed, the wearable tracker comprising a rechargeable power source;
- wherein the wearable tracker is configured to be worn by the user and becomes disconnected from signal acquisition of the second set of quantitative health data of the user when the rechargeable power source is being charged;
- wherein the first set and the second set are sequential in time to obtain around-the-clock monitoring of the quantitative health data of the user,
- wherein the first set and the second set do not overlap in time;
- wherein the stationary sensor device comprises a sensor, the sensor comprises a ferroelectret film having an active sensor section, the active sensor section is configured to be placed proximate to the user;
- wherein the active sensor section comprises a plurality of ferroelectret film layers for increased sensitivity.
