1. A detection device, configured to be placed on or under a mattress so as to detect by ballistography at least movements, a heart rate, and a respiratory rate of an individual lying on the mattress, in particular in order to monitor sleep of the individual, comprising: (11) (3)

a sensing portion comprising at least one inflatable chamber intended to contain a fluid consisting of air, intended to be positioned under the individual, in particular under one of the pressure points of the recumbent individual namely the head, chest, or lower torso;

an electronic unit arranged at a distance from the sensing portion, comprising at least one pressure sensor, intended to be positioned externally to the bedding, in particular close to the edge of the mattress or bedding; and

a transmitting portion, interposed between the sensing portion and the electronic unit, comprising at least one channel, establishing a fluid connection between the inflatable chamber and the sensor so that the electronic unit receives the pressure changes induced by movements of the individual.

2. The device of claim 1, further comprising an air pump and a discharge valve, preferably associated with the electronic unit, the air pump and the discharge valve able to be used by the electronic unit to inflate and/or deflate the sensing portion. (1) (0)

3. The device of claim 1, wherein a plurality of braces are provided in the inflatable chamber joining the upper and lower walls of the inflatable chamber such that the chamber, even when under pressure, has a thickness that is much smaller than its length (L2) and width (L1). (0)

4. The device of claim 1, wherein the distance (D) between the sensing portion and the electronic unit is greater than 10 cm. (0)

5. The device of claim 1, wherein the electronic unit comprises a module for shaping the sensed signals and a wireless communication module. (0)

6. The device of claim 1, further comprising a temperature sensor and/or a humidity sensor. (0)

7. The device of claim 1, wherein the device in a deflated state is in the form of a flexible sheet that is foldable, can be rolled up, and is washable. (0)

8. The device of claim 1, wherein the channel of the transmitting portion comprises a solid flexible rod preventing the complete collapse of the upper wall against the lower wall. (1) (0)

9. The device of claim 8, wherein: (1) (2)

11. The device of claim 1, wherein the width (W1) of the transmitting portion is substantially the same as the width (L1) along a Y axis of the sensing portion. (0)

12. The device according to claim 1, wherein the gas dead volume within the transmitting portion is minimal, preferably less than 5 cm³. (0)

13. A kit comprising a detection device according to claim 1 and a slipcover, the detection device being configured for insertion into the slipcover. (0)

14. A detection system comprising at least one detection device according to claim 1, and a remote entity. (0)
