It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 and 2 are schematic structural diagrams of a flexible physiological signal detection device according to an embodiment of the present disclosure. Fig. 3 illustrates a cross-sectional view of a flexible physiological signal detection device according to an embodiment of the present disclosure. As shown in fig. 1, 2 and 3, the device 1 comprises a flexible substrate 11, a physiological signal sensor 12, a force application member 13 and a force application control member (not shown).
And the flexible substrate 11 is used for carrying the physiological signal sensor 12 and the force application part 13 and is also used for attaching the device to the body surface of a living body. The physiological signal sensor 12 is located on the flexible substrate 11 at a position close to the surface of the body surface of the living body, is partially embedded in the flexible substrate 11, and is used for directly contacting with the body surface of the living body to acquire the physiological signal of the living body. And the force application control component is connected with the physiological signal sensor 12 and the force application component 13 and is used for determining the power supply voltage for supplying power to the force application component 13 according to the physiological signal. And the force application component 13 is positioned in the flexible substrate 11 and above the physiological signal sensor 12 and is not in contact with the physiological signal sensor 12, and is used for applying pressure to the physiological signal sensor 12 through deformation generated after power supply by the power supply voltage so as to change the contact force between the physiological signal sensor 12 and the body surface of a living body.
In this embodiment, the force application control member may be flexible and may be disposed inside the flexible substrate to reduce the volume of the apparatus. The force application control component may also be disposed outside the flexible substrate, as the present disclosure is not limited thereto. The material used for preparing the flexible substrate may be a flexible material such as Polydimethylsiloxane (PDMS).
In the present embodiment, fig. 4 shows a schematic diagram of an application scenario of a flexible physiological signal detection device according to an embodiment of the present disclosure. As shown in fig. 4, the flexible physiological signal detection device can be directly attached to the back of the hand (i.e. the body surface of the living body) of the human body to detect the physiological signal of the human body.
In this embodiment, the pre-prepared physiological signal sensor can be transferred to the flexible substrate by a transfer technique or the like. The physiological signal sensor may be made by extensible flexible electronics.
In this embodiment, the force application component can be prepared directly during the process of preparing the flexible substrate by using a mask or other techniques, or the required force application component can be prepared in advance and then implanted into the flexible substrate. The skilled person can set the preparation of the force applying component and the implantation of the flexible substrate according to actual needs, and the disclosure is not limited thereto.
The flexible physiological signal detection device provided by the embodiment of the disclosure can ensure that the device and the body surface of the organism can be tightly attached according to the contact force between the physiological signal adjustment device and the body surface of the organism, and improves the accuracy and stability of the detected physiological signal.
In one possible implementation, the device may further comprise an adhesive layer. The adhesive layer is positioned on the surface of the flexible substrate close to the body surface of the living body to increase the adhesion between the flexible substrate and the body surface of the living body. This improves the adhesion of the device to the body surface.
In one possible implementation, determining a supply voltage for powering the force application component from the physiological signal may include:
determining the current contact force between the physiological signal sensor and the body surface of the organism according to the intensity of the physiological signal;
determining a pressure difference value according to the difference value of the current contact force and the target contact force;
and determining the power supply voltage according to the current power supply voltage of the force application component, the pressure difference value and the corresponding relation between the power supply voltage difference value and the pressure difference value.
In this implementation, the target contact force may be set according to the type of physiological signal that needs to be acquired, the position of the device on the body surface of the living body, and the like. The larger the contact force of the target is, the closer the device is contacted with the body surface of the organism, and the higher the accuracy and stability of the detected physiological signal are.
In one possible implementation, the force application member may be disposed in a flexible substrate, and the material of the force application member may include an electroactive polymer.
In this implementation, the smart material (Intelligent material) is a novel functional material that can sense external stimuli, can judge and appropriately process, and can be executed by itself. Among them, an Electroactive Polymer (EAP) material such as an Ionic Polymer-Metal Composites (IPMC) is used as a material of the force application member. Electroactive polymers are one type of smart materials that have relatively special electrical and mechanical properties. The EAP material can generate larger deformation after being induced by an electric field, has large deformation rate and quick response, and can quickly recover to the original shape after the electric field is eliminated. By means of the characteristics of the electroactive polymer, the force application component generates deformation after being electrified, and transmits pressure to the physiological signal sensor through the force generated by deformation. The higher the supply voltage received by the force application member, the greater the deformation generated by the force application member.
In one possible implementation, the force application members may be arranged in an array, or alternatively, the force application members may be of unitary construction.
In this implementation, the force application member may be composed of a plurality of force application units, the material of the force application units is an electroactive polymer, and the plurality of force application units are arranged in an array in the flexible substrate. The force application unit can be in the shape of a disk, a sphere, an ellipsoid, a column, etc. For example, the plurality of force application units of the force application component are spherical and distributed in a lattice manner in the flexible substrate, so that the force application component can generate out-of-plane displacement due to the distribution of the plurality of force application units in the lattice manner under the action of the power supply voltage, and provide pressure to the physiological signal sensor below.
In this implementation, the force application member may also be an integral structure with a certain shape, which ensures that the force application member can apply pressure to the physiological signal sensor below under the action of the power supply voltage.
In one possible implementation, the distance between the force application component and the physiological signal sensor may be less than or equal to a distance threshold.
In this implementation, the force application member and the signal sensor are not in contact with each other, and adverse effects of the power supply voltage on the physiological signal sensor can be avoided. The distance between the force application component and the physiological signal sensor can be smaller than or equal to a distance threshold value, so that the force application component can apply force to the physiological signal sensor under the action of the power supply voltage, and meanwhile, the physiological signal sensor cannot be damaged by pressure applied by the force application component. The distance threshold may be set according to the flexibility of the physiological signal sensor, the size change of the force application member before and after deformation, and the like, which is not limited by the present disclosure.
In one possible implementation, the thickness of the device may be 0.5mm to 5 mm.
In this implementation, reducing the thickness of the device can improve the adhesion effect of the flexible substrate and the body surface of the living body, and enhance the contact force between the physiological signal sensor and the body surface of the living body.
Fig. 5 illustrates a cross-sectional view of a flexible physiological signal detection device according to an embodiment of the present disclosure. In one possible implementation, as shown in fig. 5, the surface of the physiological signal sensor contacting the body surface of the living body and the surface of the flexible substrate attached to the body surface of the living body are at the same horizontal plane.
In this implementation, the physiological signal sensor can be completely embedded in the flexible substrate, so that the surface of the physiological signal sensor contacting with the body surface of the living body and the surface of the flexible substrate attached to the body surface of the living body are in the same level, and the attachment between the device and the body surface of the living body is improved.
In one possible implementation, the physiological signal may include at least one of a body temperature signal, a blood pressure signal, a heart rate signal, and the like, which are related to the physiology of the living organism, and the disclosure is not limited thereto.
It should be noted that, although the flexible physiological signal detection device is described above by taking the above-mentioned embodiment as an example, those skilled in the art can understand that the disclosure should not be limited thereto. In fact, the user can flexibly set each part according to personal preference and/or actual application scene as long as the technical scheme of the disclosure is met.
