Abstract

A child soothing device includes a soothing structure includes an outer layer and an inner layer, and one or more artificial muscles disposed between the inner layer and the outer layer of the soothing structure and communicatively coupled to a controller. Each of the one or more artificial muscles includes a housing comprising an electrode region and an expandable fluid region and a dielectric fluid housed within the housing. Each of the one or more artificial muscles also includes an electrode pair positioned in the electrode region of the housing, the electrode pair including a first electrode and a second electrode. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region, thereby applying pressure to the inner layer of the soothing structure.

First claim

What is claimed is:

1 . A child soothing device comprising:
a soothing structure comprising an outer layer and an inner layer; and one or more artificial muscles disposed between the inner layer and the outer layer of the soothing structure and communicatively coupled to a controller, wherein each of the one or more artificial muscles comprise:
a housing comprising an electrode region and an expandable fluid region;
a dielectric fluid housed within the housing; and
an electrode pair positioned in the electrode region of the housing, the electrode pair comprising a first electrode and a second electrode, wherein the electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region, thereby applying pressure to the inner layer of the soothing structure.

2 . The child soothing device of claim 1 , wherein the soothing structure comprises a wearable soothing structure.

3 . The child soothing device of claim 2 , wherein the wearable soothing structure is a swaddle comprising a central portion and a plurality of flaps, each comprising a plurality of artificial muscles disposed therein.

4 . The child soothing device of claim 1 , wherein the soothing structure comprises a supportive soothing structure.

5 . The child soothing device of claim 1 further comprising a pressure sensor communicatively coupled to the controller, wherein the pressure sensor is configured to output a current pressure value to the controller and actuation of the electrode pair is based on the current pressure value.

6 . The child soothing device of claim 1 further comprising a warming element disposed under the outer layer of material of the soothing structure and communicatively coupled to the controller, wherein the controller is configured to output a warming value to the warming element.

7 . The child soothing device of claim 1 , wherein:
the first electrode and the second electrode each comprise two or more tab portions and two or more bridge portions; each of the two or more bridge portions interconnects adjacent tab portions; and at least one of the first electrode and the second electrode comprises a central opening positioned between the two or more tab portions and encircling the expandable fluid region.

8 . The child soothing device of claim 7 , wherein the first electrode and the second electrode each includes two pairs of tab portions and two pairs of bridge portions, each bridge portion interconnecting adjacent a pair of adjacent tab portions, each tab portion diametrically opposing an opposite tab portion.

9 . The child soothing device of claim 7 , wherein:
when the electrode pair is in the non-actuated state, the first electrode and the second electrode are non-parallel to one another; and when the electrode pair is in the actuated state, the first electrode and the second electrode are parallel to one another, such that the first electrode and the second electrode are configured to zipper toward one another and toward the central opening when actuated from the non-actuated state to the actuated state.

10 . The child soothing device of claim 1 , wherein the one or more artificial muscles disposed in the child soothing device comprise a plurality of artificial muscles arranged in a single layer.

11 . The child soothing device of claim 1 , wherein the controller is configured to:
receive a current pressure value from the pressure sensor; output an updated pressure value to the one or more artificial muscles; and modify actuation of at least one of the one or more artificial muscles based upon the updated pressure value.

12 . The child soothing device of claim 1 , wherein the one or more artificial muscles are configured to periodically actuate and de-actuate according to a periodicity parameter.

13 . The child soothing device of claim 12 , wherein the periodicity parameter determines a rate of actuation and de-actuation of the one or more artificial muscles.

14 . A method for actuating a child soothing device, the method comprising:
providing a voltage using a power supply electrically coupled to an electrode pair of an artificial muscle, the artificial muscle disposed between an inner layer and an outer layer of a soothing structure of the child soothing device, wherein:
the artificial muscle comprises a housing having an electrode region and an expandable fluid region;
the electrode pair is positioned in the electrode region of the housing;
the electrode pair comprises a first electrode and a second electrode; and
a dielectric fluid is housed within the housing; and
applying the voltage to the electrode pair of the artificial muscle, thereby actuating the electrode pair such that the dielectric fluid is directed into the expandable fluid region of the housing and expands the expandable fluid region, thereby applying pressure to the inner layer of the soothing structure.

15 . The method of claim 14 , wherein a pressure sensor is affixed to the housing and communicatively coupled to a controller, and the method further comprises receiving heartbeat data from a sensor device pertaining to a user wearing the sensor device, wherein the heartbeat data is used to reproduce a heartbeat of the user wearing the sensor device via actuation and de-actuation of the artificial muscle.

16 . The method of claim 14 further comprising:
outputting, via a pressure sensor affixed to the housing of the artificial muscle and communicatively coupled to a controller, a pressure value to the controller;
receiving, from the controller, an updated pressure value at the artificial muscle to maintain a consistent amount of periodic actuation pressure at the inner layer of the child soothing device based upon the pressure value; and
adjusting the actuation of the artificial muscle to maintain the consistent amount of actuation pressure at the inner layer of the child soothing device.

17 . The method of claim 16 further comprising:
receiving a current pressure value from the pressure sensor;
outputting an updated pressure value to the one or more artificial muscles; and
modifying actuation of the artificial muscle based upon the updated pressure value to maintain the consistent amount of periodic actuation pressure at the inner layer of the child soothing device.

18 . The method of claim 16 , wherein the artificial muscle is one of a plurality of artificial muscles and the method further comprises adjusting the actuation of each of the plurality of muscles to maintain the consistent amount of periodic actuation pressure at the inner layer of the child soothing device.

19 . A child soothing system comprising:
a child soothing device comprising:
a soothing structure comprising an outer layer and an inner layer;
network interface hardware communicatively coupled to a sensor device and configured to receive heartbeat data from the sensor device pertaining to a user wearing the sensor device;
one or more artificial muscles disposed between the inner layer and the outer layer of the soothing structure and communicatively coupled to a controller, wherein each of the one or more artificial muscles comprise:
a housing comprising an electrode region and an expandable fluid region;
a dielectric fluid housed within the housing; and
an electrode pair positioned in the electrode region of the housing, the electrode pair comprising a first e
