Description

Technical Field

[0001] This invention relates to the field of smart wearable technology, and in particular to a smart monitoring garment for monitoring sleep breathing and sleeping posture. Background Technology

[0002] Sleep disorders, especially obstructive sleep apnea, abnormal sleeping postures, and abnormal body movements during sleep, have become a significant public health issue. While existing polysomnography (PSG) can provide a relatively comprehensive sleep assessment, it suffers from drawbacks such as complex equipment, highly invasive procedures, limited testing environments, poor patient compliance, and difficulty in meeting the needs for long-term continuous home monitoring. Existing wearable devices, while offering some portability, generally suffer from challenges in balancing comfort and accuracy, low system integration, insufficient multi-parameter fusion capabilities, and inconvenient external module installation and removal.

[0003] Currently, common wristband, chest strap, patch, or single-point sleep monitoring devices can typically only acquire single information such as respiration, heart rate, or body movement, making it difficult to achieve coordinated analysis of respiration, sleep posture, and limb movement. Their sensors often adopt an external or adhesive structure, affecting wearing comfort and making them unsuitable for prolonged nighttime wear. At the same time, the lack of a unified layout and synchronous acquisition mechanism among multiple sensor signals makes it difficult to accurately reflect the correlation between signals from different parts of the body. In addition, the way external processing modules are connected to clothing is usually not conducive to quick disassembly, causing inconvenience for cleaning, maintenance, and long-term use.

[0004] To address this, a smart monitoring garment for monitoring sleep breathing and sleeping posture is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a smart monitoring garment for monitoring sleep breathing and sleeping posture, aiming to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides an intelligent monitoring garment for monitoring sleep breathing and sleeping posture, comprising a monitoring garment body, wherein a conductive transmission network and a plurality of piezoresistive sensing units are integrally formed on the monitoring garment body, the plurality of piezoresistive sensing units are spaced apart, and the plurality of piezoresistive sensing units are electrically connected to the conductive transmission network. The monitoring garment is equipped with a connecting component, and an edge computing module is detachably connected to the connecting component. The edge computing module is electrically connected to the conductive transmission network. The edge computing module is used to synchronously acquire, convert analog to digital, filter, extract features and jointly analyze the electrical signals output by several piezoresistive sensing units to obtain sleep breathing state, sleep posture state and body movement state.

[0007] According to the present invention, a smart monitoring garment for monitoring sleep breathing and sleeping posture is provided, wherein a plurality of the piezoresistive sensing units are respectively disposed in the abdominal region, waist region, back region and elbow and knee region of the monitoring garment body.

[0015] The present invention discloses the following technical effects: This invention acquires information on breathing deformation, waist posture changes, back pressure distribution, and joint bending activity by arranging piezoresistive sensing units at intervals on the monitoring garment body. The signals are then uniformly converged and transmitted to the edge computing module through a conductive transmission network inside the fabric.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 Reference Figures 1-5 The present invention provides an intelligent monitoring garment for monitoring sleep breathing and sleeping posture, comprising a monitoring garment body 1, on which a conductive transmission network 2 and a plurality of piezoresistive sensing units 3 are integrally formed, the plurality of piezoresistive sensing units 3 are spaced apart, and the plurality of piezoresistive sensing units 3 are electrically connected to the conductive transmission network 2. The monitoring garment body 1 is equipped with a connecting component, and an edge computing module is detachably connected to the connecting component. The edge computing module is electrically connected to the conductive transmission network 2. The edge computing module is used to synchronously acquire, convert analog to digital, filter, extract features and jointly analyze the electrical signals output by several piezoresistive sensing units 3 to obtain sleep breathing state, sleep posture state and body movement state.

[0023] This invention acquires information on breathing deformation, waist posture changes, back pressure distribution, and joint bending activity by arranging piezoresistive sensing units 3 at intervals on the main body 1 of the monitoring garment. The signals are then uniformly aggregated and transmitted to the edge computing module through the conductive transmission network 2 inside the fabric. The detachable connection between the connecting component and the edge computing module facilitates the disassembly of the edge computing module while enabling signal transmission, thereby improving the system integration, ease of use, washability, and monitoring accuracy of the smart monitoring garment.

[0024] This invention combines high comfort, high integration, multi-part collaborative monitoring capabilities, and easy disassembly and maintenance, meeting the application needs of sleep health management and home-based continuous monitoring.

[0025] To further optimize the design, several piezoresistive sensing units 3 are respectively installed in the abdominal, waist, back, and elbow / knee regions of the monitoring garment body 1. The edge computing module is used to extract respiratory rate, respiratory amplitude, and apnea duration parameters from the abdominal signals monitored by the piezoresistive sensing units 3 in the abdominal region; to extract sleeping posture type, turning frequency, and position holding time parameters from the waist and back signals monitored by the piezoresistive sensing units 3 in the waist and back regions; and to extract limb movement frequency, joint range of motion, and body movement characteristic parameters from the elbow and knee signals monitored by the piezoresistive sensing units 3 in the elbow and knee regions.

[0026] The scheme is further optimized. The piezoresistive sensing unit 3 includes an upper electrode and a lower electrode, and a piezoresistive material is fixedly embedded between the upper electrode and the lower electrode. Both the upper and lower electrodes are integrally formed on the monitoring garment body 1, and both the upper and lower electrodes are electrically connected to the conductive transmission network 2.

[0027] During wear, the pressure generated by the rise and fall of human breathing, shifts in sleeping posture, and turning over, along with fabric deformation, acts on the piezoresistive sensing unit 3, causing deformation of the intermediate piezoresistive material. This alters the density of its internal conductive pathways, resulting in a regular change in resistance. The upper and lower electrodes serve as the signal acquisition poles, stably capturing the analog electrical signals generated by the resistance changes and transmitting these signals to the conductive transmission network 2 in real time. This double-layer electrode structure, sandwiching the piezoresistive material, ensures uniform sensing force and sensitive signal response, avoiding the signal drift and unstable acquisition problems of single-layer sensing structures. This effectively improves the accuracy and stability of sleep breathing and posture pressure signal acquisition.

[0028] The design is further optimized by integrating the upper electrode with the monitoring garment body 1 through knitting, weaving, or knitting; the lower electrode is also integrated with the monitoring garment body 1 through knitting, weaving, or knitting. This integrated weaving process deeply fuses the electrodes with the fabric fibers of the monitoring garment body 1, resulting in a smooth, soft, and highly conforming overall structure that provides a comfortable, non-invasive fit, meeting the needs of long-term, unobtrusive sleep monitoring. Simultaneously, the integrated structure eliminates the risk of delamination and detachment, effectively preventing issues such as electrode loosening, detachment, and thread breakage during repeated bending, washing, and stretching, significantly improving the durability and stability of the sensing structure. The integrated arrangement of the electrodes and fabric allows for precise, synchronized deformation following subtle changes in the human body surface, maximally replicating the real pressure and deformation characteristics of human breathing and sleep posture changes, ensuring the continuity and accuracy of the sensing signal from a structural perspective.

[0029] The design was further optimized by using a magnetic interface for the connecting parts, which is located at the bottom of one side of the monitoring garment body 1.

[0030] The magnetic interface features automatic alignment, magnetic locking, and quick assembly / disassembly. During assembly, the edge computing module quickly attaches and connects; during disassembly, it can be simply removed without cumbersome plugging and unplugging, significantly improving ease of use. The interface is located on the side bottom of the garment, avoiding pressure areas on the back, chest, and abdomen. This prevents the module from being squeezed or bumped when the user turns over or experiences pressure during sleep, thus avoiding affecting wearing comfort and sleep quality. It also effectively prevents the module from falling off under pressure. The magnetic connection ensures stable electrical contact, is not easily affected by daily stretching or slight bending, and guarantees continuous and stable signal transmission. Furthermore, the monitoring garment body can be washed separately after disassembly, improving the device's maintainability and lifespan.

[0031] The design has been further optimized, with both the upper and lower electrodes made of conductive fibers, conductive yarns, conductive coated fibers, metal composite fibers, or conductive polymer fibers. All materials possess excellent flexibility, bending resistance, and conductive stability, adapting to integrated fabric weaving processes. They can withstand repeated stretching, bending, and rubbing of the monitoring garment without breakage, delamination, or conductive failure. Different materials can be flexibly selected based on monitoring accuracy and usage scenarios, all ensuring uniform electrode conductivity and sensitive signal transmission, stably capturing even weak resistance changes in piezoresistive materials. Simultaneously, the flexible conductive fiber material conforms to human skin, is breathable, and non-irritating, balancing the device's electrical performance with wearable comfort, making it suitable for long-term continuous home sleep monitoring.

[0032] Further optimization of the scheme involves using piezoresistive materials in sheet, strip, mesh, porous, or foam forms. Sheet and strip piezoresistive materials have a regular structure and are suitable for large, gently deformable areas such as the chest, abdomen, and waist, allowing for uniform acquisition of respiratory fluctuations and posture pressure signals. Mesh, porous, and foam piezoresistive materials possess excellent flexibility, compression resilience, and deformation adaptability, making them suitable for areas with large bending amplitudes and complex deformations, such as joints and lateral movements, enabling precise response to minute pressure changes. These multi-form piezoresistive materials can be strategically deployed according to the movement characteristics of different monitoring sites on the human body, ensuring sensitive sensing response and uniform force distribution in each area, effectively improving the comprehensiveness and accuracy of multi-site collaborative monitoring.

[0033] Further optimization of the scheme involves the conductive transmission network 2 employing a conductive yarn network, flexible conductive tape, or flexible circuitry. The conductive yarn network can be woven synchronously with the fabric, offering high integration, good breathability, and washability, making it suitable for daily wear and washing conditions. The flexible conductive tape exhibits uniform conductivity and strong tensile strength, enabling stable transmission of multiple sensor signals and preventing signal attenuation. The flexible circuit features neat wiring and strong anti-interference capabilities, reducing crosstalk issues between multiple signals. All three structures possess high flexibility, bend resistance, and high stability, adapting to the repeated deformation of the monitoring garment body 1. This allows for the synchronous, low-loss, and interference-free transmission of the weak electrical signals collected by each piezoresistive sensing unit 3 to the edge computing module, ensuring the integrity and real-time performance of multi-channel sensor data transmission.

[0034] The design was further optimized so that the front, back and sleeves of the monitoring garment body 1 are made of four-sided weave; the connection between the monitoring garment body 1 and the upper and lower electrodes is made of air-layer jacquard weave.

[0035] It adopts a four-sided weave, which has a flat and dense structure, a soft feel, and uniform stretch. It fits the human body surface and can effectively reduce sensor interference caused by loose clothing and ensure monitoring stability.

[0036] The connection area between the monitoring garment body 1 and the upper and lower electrodes is woven with an air-layer jacquard weave. This structure has a three-dimensional sandwich structure, which can firmly wrap and fix the electrode structure, preventing electrode displacement, wrinkling, and detachment. At the same time, it improves the elasticity and deformation adaptability of the electrode area, ensuring that the electrodes can respond synchronously with the deformation of the human body. The double-layer differentiated webbing structure takes into account both overall wearing comfort and local sensing structure stability, effectively improving the overall monitoring accuracy and durability of the device.

[0037] The solution is further optimized so that the edge computing module can interact with mobile phones, bedside terminals, cloud platforms, or other external processing devices. The edge computing module can upload sleep breathing data, sleep posture data, body movement data, and health analysis results to various external terminal devices in real time, realizing the visualization, remote, and systematic management of sleep monitoring data. This facilitates long-term sleep health tracking, data analysis, and abnormal risk warnings, and significantly expands the intelligent application scenarios of the device.

[0038] Example 2 The difference between this embodiment and Embodiment 1 is that the connecting component adopts a plug-in interface with quick disassembly and assembly function, a conductive snap-on interface, or other detachable electrical connection structure.

[0039] Further optimize the scheme by manufacturing the monitoring garment body 1 into a top, pajamas, vest, bodysuit, underwear-style monitoring garment, or other wearable fabric carrier.

[0040] The design has been further optimized. A flexible, breathable, and sweat-proof cushioning layer is installed on the outside of the piezoresistive sensing unit 3. The flexible, breathable, and sweat-proof cushioning layer is made of breathable and flexible fabric and is fully covered and fitted to the sensing area.

[0041] During sleep, the human body easily produces sweat. Sweat soaking the sensing unit can cause abnormal electrode conductivity and resistance baseline drift, resulting in distorted breathing and posture monitoring data. Furthermore, prolonged sweat immersion can corrode conductive structures, reducing the device's lifespan. A flexible, breathable, and sweat-proof cushioning layer isolates human sweat and skin oils without hindering pressure and deformation transmission, preventing direct contact between sweat and the piezoresistive material and electrode structure, thus completely solving the signal drift problem in humid environments. Simultaneously, the flexible layer provides a slight cushioning effect, filtering out invalid interference signals from minor friction from clothing and skin movements, further improving the recognition accuracy of weak breathing deformation signals. The breathable structure does not compromise wearing comfort, making it suitable for long-term nighttime sleep monitoring.

[0042] To further optimize the design, highly elastic adaptive bands are added to the waist and underarm sides of the monitoring garment 1, forming a full-body adaptive fit structure. Different users have different body shapes, and traditional one-piece monitoring garments are prone to localized looseness and poor fit, causing the garment to slip off the skin during sleep, tormentation, and breathing, generating a large number of invalid interference signals and severely affecting monitoring accuracy. The added highly elastic bands can adapt to the body curves of different users, always maintaining a tight fit between the sensing area and the chest, abdomen, and back, eliminating gaps in the garment. This ensures that the piezoresistive sensing unit 3 accurately captures subtle respiratory deformations and changes in posture and pressure, without creating an overly tight feeling of constriction, balancing wearing comfort and sensing fit stability, effectively solving the problems of poor body fit and significant signal interference.
