Description

Technical Field

[0001] This utility model relates to the field of sleep detection technology, specifically to an integrated piezoelectric thin film sensor. Background Technology

[0002] A piezoelectric thin-film sensor is a sensor that uses the piezoelectric effect to convert mechanical energy into electrical energy. It is suitable for monitoring vital signals on the surface of human skin or implanted inside the human body.

[0003] For example, patent CN215383962U discloses a piezoelectric thin film sensor, including a first protective shell, which is flexible; and a piezoelectric thin film body, which is fixed inside the first protective shell. This utility model's technical solution uses a flexible first protective shell to protect the piezoelectric thin film body, thereby improving its tensile and bending strength while still allowing it to collect vital signals from the human body, thus extending its service life.

[0004] In practice, most sleep monitoring mattresses are equipped with piezoelectric film sensors to intelligently detect a person's sleep status. However, using only a single piezoelectric film sensor cannot comprehensively detect the dynamics of a person's entire body. Furthermore, the pressure exerted by the body on the mattress can easily cause excessive stretching and bending of the piezoelectric film sensor, leading to excessive costs.

[0005] It is evident that the aforementioned problems with existing technologies urgently need to be addressed. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, one aspect of the purpose of this utility model is to provide an integrated piezoelectric thin film sensor to solve the problems that a single piezoelectric thin film sensor cannot fully detect the dynamics of the sleeping person's whole body, and is easily damaged by excessive stretching and bending due to the large pressure of the human body on the mattress, resulting in excessive cost.

[0007] To achieve the above objectives, this utility model provides an integrated piezoelectric thin film sensor, including a piezoelectric thin film sensor assembly and a pressure sensor assembly. The ends of the piezoelectric thin film sensor assembly and the pressure sensor assembly are respectively provided with a first connection end and a second connection end. Both the first connection end and the second connection end are provided with connecting lines to form a connecting line assembly to maintain electrical connection.

[0008] Preferably, the piezoelectric thin film sensor assembly includes a piezoelectric thin film protective shell, and the piezoelectric thin film body is disposed inside the piezoelectric thin film protective shell.

[0009] Preferably, the piezoelectric film protective shell is made of a flexible material.

[0010] Preferably, the piezoelectric film protective shell is provided with a wire inside to connect the piezoelectric film body and the first connection end.

[0011] Preferably, the pressure sensor assembly includes multiple pressure sensor protective shells, with each layer of the pressure sensor protective shell connected together, and a pressure sensor body is disposed inside the pressure sensor protective shell.

[0012] Preferably, the protective housing of the pressure sensor is made of a flexible material.

[0013] Preferably, the inside of the pressure sensor protective housing is provided with wires to connect the pressure sensor body and the second connection terminal.

[0014] Preferably, the pressure sensor protective housing has an array of vent holes inside.

[0015] Preferably, the connecting cable assembly includes a connecting bus, and the end of the connecting bus away from the connecting cable is provided with a connecting socket.

[0017] Compared with the prior art, the integrated piezoelectric thin film sensor provided by this utility model has the following beneficial effects:

[0018] 1. By connecting multiple pressure sensor components, the mattress can be fully covered to accurately detect the dynamics of the sleeping person.

[0019] 2. The pressure sensor body and the piezoelectric film body are protected by the protective shells of each pressure sensor and the protective shell of the piezoelectric film.

[0020] 3.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, an integrated piezoelectric thin film sensor includes a piezoelectric thin film sensor assembly 1 and a pressure sensor assembly 2. The ends of the piezoelectric thin film sensor assembly 1 and the pressure sensor assembly 2 are respectively provided with a first connection end 103 and a second connection end 204. Both the first connection end 103 and the second connection end 204 are provided with connecting lines 301 to form a connecting line assembly 3 to maintain electrical connection.

[0029] The main purpose of this integrated piezoelectric thin film sensor is to cover the entire mattress through the connection of multiple pressure sensor components 2, so as to accurately detect the dynamics of the sleeping person. It also protects the pressure sensor body 202 and the piezoelectric thin film body 102 through the protective shells 201 of each pressure sensor and the protective shell 101 of the piezoelectric thin film. Furthermore, the electrical connection between the piezoelectric thin film sensor component 1 and the pressure sensor component 2 enables the transmission of electrical signals, transmitting the pressure sensed by the pressure sensor body 202 to the piezoelectric thin film sensor component 1, thereby detecting the sleep quality of the sleeping person.

[0030] In the technical solution provided by this utility model, by Figure 1 , Figure 2 and Figure 3 It is known that the piezoelectric thin film sensor assembly 1 includes a piezoelectric thin film protective shell 101, and a piezoelectric thin film body 102 is provided inside the piezoelectric thin film protective shell 101, which can protect the piezoelectric thin film body 102 and prevent the piezoelectric thin film body 102 from being damaged due to excessive stretching or bending.

[0031] Furthermore, the piezoelectric film protective shell 101 is made of a flexible material, which can buffer pressure and be bent within a certain range, allowing the piezoelectric film sensor assembly 1 to fit tightly against the sleeping person for detection.

[0032] Furthermore, the piezoelectric film protective shell 101 is equipped with wires to connect the piezoelectric film body 102 and the first connection end 103, which can provide power and also transmit and record detection data as electrical signals.

[0033] Furthermore, the pressure sensor assembly 2 includes multiple pressure sensor protective shells 201, and each layer of pressure sensor protective shell 201 is connected, which can cover the entire mattress, thereby detecting the movement of the sleeping person's whole body, making the detection data more accurate. The pressure sensor body 202 is set inside the pressure sensor protective shell 201, which can protect the pressure sensor body 202 and prevent it from being damaged by excessive stretching or bending.

[0034] Furthermore, the pressure sensor protective shell 201 is made of a flexible material, which can buffer the pressure. The flexible material can also be bent within a certain range, so that each pressure sensor body 202 fits tightly against the sleeping person's body for accurate detection.

[0035] Furthermore, the pressure sensor protective housing 201 has wires inside to connect the pressure sensor body 202 and the second connection end 204, which can provide power and transmit the detection data as electrical signals to the piezoelectric thin film sensor assembly 1 for data recording, thereby controlling various smart home devices to adjust the sleep environment.

[0036] Furthermore, the pressure sensor protective housing 201 has an array of exhaust holes 203 inside, which can exhaust the heat generated by the sleeping person and the internal circuitry.

[0037] Furthermore, the connecting line assembly 3 includes a connecting bus 302, and the end of the connecting bus 302 away from the connecting line 301 is provided with a connecting socket 303, which can provide power and data transmission to the piezoelectric thin film sensor assembly 1 and the pressure sensor assembly 2.

[0038] Working principle: First, the pressure sensor assembly 2 and the piezoelectric thin film sensor assembly 1 are placed inside the mattress;

[0039] When a person is lying on the mattress, the pressure sensor assembly 2 can detect the pressure of various parts of the person on the mattress, and the piezoelectric film sensor assembly 1 can detect the person's movements.

[0040] This allows for the detection of a person's movements during sleep, which are then aggregated into a connection bus 302 via various connection lines 301 for data transmission.

[0041] It is then powered through the connection port 303 and will also transmit monitoring data to control various smart home devices and intelligently adjust the sleep environment.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
