Abstract

A system for unobtrusively measuring bioelectric signals developed by an individual includes multiple sensors, one or more of which constitutes a capacitive sensor, embedded into or otherwise integrated into an object, such as a chair, bed or the like, used to support the individual. In one preferred embodiment, multiple capacitive sensors are incorporated into a pad provided in an incubator for unobtrusively measuring bioelectric signals from a baby under supervised care. In any case, the object serves as mounting structure that holds the sensors in place. The sensors are preferably arranged in the form of an array, with particular ones of the sensors being selectable from the array for measuring the bioelectric signals which are transmitted, such as through a wireless link, for display and/or analysis purposes.

Claims

1. An incubator comprising:

a base;

an upper housing arranged on the base;

a pad arranged in the housing and upon which an infant, who produces a bioelectric field to be measured, is adapted to be supported;

a plurality of electrical sensors integrated into the pad as an array, at least one of the plurality of electrical sensors being constituted by a capacitive-type electrical sensor; and

a controller located outside the housing and electrically linked to each of the plurality of electrical sensors, wherein activation of one or more of the plurality of electrical sensors enables the bioelectric field to be unobtrusively measured.

2. The incubator according to claim 1, wherein the plurality of electrical sensors are embedded into the pad.

3. The incubator according to claim 1, wherein the pad defines a mattress for the incubator.

4. The incubator according to claim 1, wherein the controller receives, processes, stores and displays the bioelectric signals.

5. The incubator according to claim 1, wherein the controller includes means for choosing select ones of the plurality of electrical sensors in the array to sense the bioelectric field.

6. The incubator according to claim 5, wherein each of the plurality of electrical sensors constitutes a capacitve-type electrical sensor.

7. The incubator according to claim 1, wherein the pad is removable from the housing for transporting separate from the housing.

8. The incubator according to claim 7, wherein the pad includes a handle for carrying the pad.

9. A method of sensing bioelectric signals from an infant producing a bioelectric field in an incubator having a housing including an upper portion comprising:

supporting a body portion of the infant upon a pad having a plurality of integrated electrical sensors within the housing, with at least one of the plurality of electrical sensors being constituted by a capacitive-type sensor;

measuring bioelectric signals with the plurality of electrical sensors; and

transmitting the bioelectric signals associated with the bioelectric field to a controller.

10. The method of claim 9, wherein the controller is carried by the incubator such that the controller is transported with the housing.

11. The method of claim 9, further comprising:

selecting ones of the plurality of electrical sensors from an array of the plurality of electrical sensors.

12. The method of claim 9, further comprising:

receiving, processing, storing and displaying the bioelectric signals.

13. The method of claim 9, further comprising:

removing the pad from the housing;

placing the pad in a compact configuration; and

transporting the pad separate from the housing.

14. The method of claim 13, wherein placing the pad in the compact configuration constitutes rolling up the pad, along with the plurality of electrical sensors.

15. The method of claim 13, further comprising:

using a handle attached to the pad in transporting the pad.
