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.

Claims (49)

1 . 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.

2 . The system of claim 1 , further comprising a system manager comprising a computing device for acquiring the first set of the quantitative health data of the user from the stationary sensor device.

3 . The system of claim 2 , wherein the computing device acquires the second set of the quantitative health data of the user from the wearable tracker.

4 . The system of claim 1 , wherein the charger is an inductive charger.

5 . The system of claim 1 , wherein the sensor of the stationary sensor device is the first sensor and the wearable tracker comprises a second sensor, the first sensor and the second sensor comprising different sensor types.

6 . The system of claim 5 , wherein the second sensor comprises microelectromechanical system.

7 . The system of claim 1 ,

further comprising

a first system manager comprising a first computing device for acquiring the quantitative health data of the user from the stationary sensor;

a second system manager comprising a second computing device for acquiring quantitative health data of the user from the stationary sensor.

8 . The system of claim 1 , wherein the stationary sensor device further comprises an inactive sensor section of the ferroelectret film, the inactive sensor section being proximate to an interference source.

9 . The system of claim 1 ,

further comprising a webbed tubing,

wherein the active sensor section is disposed in the webbed tubing to protect from damage.

10 . The system of claim 1 , wherein the wearable tracker is selected from a smartphone, a watch, or a chest-worn device.

11 . The system of claim 1 , wherein the plurality of ferroelectret film layers for increased sensitivity is at least two layers.

12 . The system of claim 11 , wherein the plurality of ferroelectret film layers are formed by folding the ferroelectret film over itself.

13 . The system of claim 1 , wherein the plurality of ferroelectret film layers are formed by folding the ferroelectret film over itself.

14 . The system of claim 1 , wherein the plurality of ferroelectret film layers are formed by folding the ferroelectret film over itself in a C shape.

15 . The system of claim 1 , wherein the plurality of ferroelectret film layers are formed by folding the ferroelectret film over itself in a spiral shape.

16 . 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 and an inactive sensor section, the active sensor section is configured to be placed proximate to the user and the inactive sensor section being proximate to an interference source;

wherein the active sensor section comprises a plurality of ferroelectret film layers for increased sensitivity formed by folding the ferroelectret film over itself in a C shape.

17 . 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 and an inactive sensor section, the active sensor section is configured to be placed proximate to the user and the inactive sensor section being proximate to an interference source;

wherein the active sensor section comprises a plurality of ferroelectret film layers for increased sensitivity formed by folding the ferroelectret film over itself in a spiral shape.

18 . The system of claim 16 ,

further comprising a webbed tubing,

wherein the active sensor section is disposed in the webbed tubing to protect from damage.

19 . The system of claim 17 ,

further comprising a webbed tubing,

wherein the active sensor section is disposed in the webbed tubing to protect from damage.
