[0044] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] See Figure 1 The present invention provides a method for thermally transferring a graphene sensor onto a wearable fabric, the method comprising the following steps:

[0046] S101, Prepare a graphene sensor, the sensor comprising graphene material and having sensor elements for measuring and detecting biological or environmental parameters;

[0047] Specifically, one can select a single-layer graphene material for preparing the graphene sensor; select a rigid or flexible substrate to prepare the sensor base; transfer the single-layer graphene from the growth substrate to the sensor base material; design the sensor element structure according to the biological or environmental parameters to be measured and detected; add an energy supply to provide the power required for the sensor to operate; and encapsulate the graphene sensor using encapsulation or protective materials.

[0048] For example, the specific steps of one implementation are as follows:

[0049] Selecting monolayer graphene materials for fabricating graphene sensors: When selecting graphene materials, their conductivity, stability, and growth quality can be considered. For example, monolayer graphene that has undergone high-quality growth and characterization can be selected, such as uniform monolayer graphene films grown by chemical vapor deposition (CVD).

[0050] Choose a rigid or flexible substrate to fabricate the sensor base: Depending on the requirements, an appropriate number of rigid or flexible substrates can be selected for fabricating the graphene sensor base. For example, the rigid substrate can be a silicon wafer or a glass substrate, while the flexible substrate can be a polymer film material, such as polyimide (PI) or polyester (PET).

[0051] Transferring monolayer graphene from a growth substrate to a sensor base material: Graphene transfer typically employs conventional mechanical or chemical exfoliation methods. For example, in mechanical exfoliation, adhesive or spin-exfoliation methods can be used to peel graphene from a metal substrate and transfer it to the sensor base material.

[0052] The sensor element structure is designed based on the biological or environmental parameters that need to be measured and detected. The structural design of the sensor element can be optimized according to the actual application requirements. For example, when designing a sensor for detecting biological parameters of genes or proteins, specific biomolecules, such as antibodies or DNA probes, can be modified on graphene to achieve specific detection.

[0053] Adding an energy supply to provide the power needed for sensor operation: To provide the power required by the sensor, a battery, such as a lithium battery or a flexible thin-film solar cell, can be integrated into the sensor. Another approach is to use wireless charging technologies, such as electromagnetic induction or resonant coupling, to provide a continuous power supply to the sensor.

[0054] Encapsulating graphene sensors with encapsulation or protective materials: To protect graphene sensors from environmental interference and damage, methods such as polymer encapsulation or metal encapsulation can be used. For example, polymer encapsulation materials, such as polyimide (PI) films, can be used to cover and protect the graphene sensor and sensor elements.

[0055] The specific steps of another implementation method are as follows:

[0056] Choosing monolayer graphene materials for fabricating graphene sensors: In addition to traditional monolayer graphene materials, graphene derivatives with special functions or properties, such as graphene oxide (GO) or functionalized graphene, can be considered. These derivatives can be chemically modified or synthesized to possess specific electrical or chemical properties to achieve higher sensitivity and selectivity.

[0057] Choose between rigid or flexible substrates to fabricate the sensor base: In addition to the conventional choice of rigid or flexible substrates, advanced substrate materials can be considered, such as flexible substrate materials commonly used in flexible organic electronics, such as polydimethylsiloxane (PDMS), or steel substrates with higher rigidity and stability.

[0058] Transferring monolayer graphene from a growth substrate to a sensor base material: In addition to traditional mechanical or chemical exfoliation methods, novel transfer techniques, such as layer-by-layer transfer, can be explored. This method utilizes tearable polymer layers to transfer graphene layer by layer, allowing for precise control and positioning during the transfer process.

[0059] Based on the biological or environmental parameters to be measured and detected, the sensor element structure is designed: in addition to conventional sensor structure design, nanostructures or micro / nano fabrication techniques can be introduced for nanoscale control and optimization. For example, nanowires or nanoparticles can be used to enhance the sensitivity and selectivity of the sensor, or nanochannels or microarrays can be used to increase the usable detection area of ​​the sensor.

[0060] Add an energy supply to provide the power required for sensor operation: In addition to traditional battery or wireless charging power, consider using ambient energy for self-powering. For example, use flexible piezoelectric materials as energy harvesters to convert energy from human movement or environmental vibrations into electricity to achieve sensor self-powering.

[0061] Encapsulating graphene sensors with encapsulation or protective materials: In addition to traditional polymer or metal encapsulation, novel materials can be considered for encapsulation to achieve better protection and stability. For example, diamond films with high-temperature stability and wear resistance can be used as encapsulation materials for graphene sensors to increase their durability and lifespan.

[0062] S102, Prepare a wearable fabric having a preset temperature and surface properties to ensure compatibility with graphene thermal transfer;

[0063] When preparing wearable fabrics, the following preferred methods can be used to ensure their compatibility with graphene thermal transfer printing:

[0064] Material and fiber structure selection: Choose fiber materials with high thermal stability and low shrinkage, such as polyester, nylon, or cotton. These materials can maintain shape stability at high temperatures and reduce fabric shrinkage during the heat transfer process.

[0065] Surface treatment: Special surface treatments are applied, such as using adhesives, tackifiers, or modifiers. These treatments increase the adhesion and wettability of the fabric surface, allowing it to bond better with graphene materials.

[0066] Temperature control: During the preparation process, the fabric is heated to a preset temperature. This ensures that the fabric can adapt to the heat transfer temperature of graphene and provides sufficient heat to promote the bonding between graphene and the fabric.

[0067] Surface coating and functionalization: Special coatings or functionalizations are applied to the fabric surface to increase its interaction with graphene. For example, using special coating agents or functional materials, such as agglomerants or soluble polymers, can improve the positioning and adhesion of graphene on the fabric and enhance its bonding strength with the fabric.

[0068] By employing these preferred implementation methods, it can be ensured that the prepared wearable fabric has preset temperature and surface properties to be compatible with graphene thermal transfer, thereby achieving a high-quality combination between graphene sensors and fabric.

[0069] S103, Positioning the sensor element of the graphene sensor on the substrate or film of the graphene sensor.

[0070] Specifically, a sensor substrate for graphene sensors can be selected, and graphene material can be transferred from the growth substrate to the selected sensor substrate; the sensor element of the graphene sensor can be positioned on the sensor substrate to ensure that the position of the sensor element is accurate and in uniform contact with the substrate; the sensor element can be fixed on the sensor substrate, and any tiny gaps between the graphene sensor element and the substrate can be filled with a gap-filling material; after the graphene sensor element is fixed, the graphene and the substrate can be fixed again by controlling the preset temperature and pressure.

[0071] Preferably, one specific implementation method is as follows:

[0072] Selecting a sensor substrate for a graphene sensor involves transferring graphene material from the growth substrate to the selected sensor substrate. In addition to traditional substrate selection and graphene transfer methods, novel transfer techniques, such as localized chemical modification, can be considered. This method utilizes specific chemical modifiers to react only in specific regions of the sensor substrate, achieving selective transfer of graphene material and thus improving transfer efficiency and accuracy.

[0073] Positioning the graphene sensor element on the sensor substrate ensures accurate positioning and uniform contact between the sensor element and the substrate. In addition to conventional alignment techniques, advanced nanoscale alignment techniques can be considered. For example, photolithography or electron beam lithography can be used to create nanoscale alignment marks on the sensor substrate to achieve higher precision alignment and contact.

[0074] The sensor element is fixed to the sensor substrate, and any tiny gaps between the graphene sensor element and the substrate are filled with a gap-filling material. In addition to traditional fixing and filling methods, deformable filling materials can be considered. For example, materials with shape memory function, such as polydimethylsiloxane (PDMS) or special alloys, can be used to fill tiny gaps and change shape and size upon curing or activation, thereby achieving better contact and coupling effects.

[0075] After the graphene sensor element is fixed, the graphene is re-fixed to the substrate by pre-setting temperature and pressure control. In addition to conventional temperature and pressure control, local heating or local stress modulation techniques can be considered. For example, using a local heating source or local stress control device, specific areas of the graphene and substrate can be precisely controlled to achieve better fixation and contact quality.

[0076] These preferred implementation methods can improve the accuracy and stability of the graphene sensor fabrication process and achieve better results in sensor performance and measurement results.

[0077] S104, preheat the graphene sensor and wearable fabric to the corresponding preset temperature to ensure that the graphene sensor can be combined with the wearable fabric.

[0078] Specifically, thermal transfer equipment or hot pressing devices can be used to preheat the graphene sensor and fabric, and to ensure temperature uniformity and stability.

[0079] Preferably, this invention develops an infrared radiation-based preheating technology. This technology utilizes the characteristics of infrared radiation to rapidly and uniformly heat graphene sensors and fabrics, thereby achieving accurate preset temperatures. Compared to traditional heat transfer or hot pressing techniques, this infrared radiation preheating technology offers faster heating speeds and better temperature control.

[0080] Infrared radiation is a type of electromagnetic radiation with wavelengths between visible light and microwaves. It is highly efficient and fast in energy transfer. Infrared radiation-based preheating technology utilizes this property, preheating the material by emitting infrared light into it.

[0081] A key advantage of this preheating technology is its ability to rapidly transfer energy directly to the material without relying on heat conduction or convection. This makes the preheating process more efficient and allows for a rapid increase in material temperature. Furthermore, this method offers excellent temperature control, enabling precise control of the material's heating temperature.

[0082] Infrared radiation-based preheating technology can be applied to various materials and applications, including the combination of graphene sensors and wearable fabrics. Infrared light can be radiated onto the graphene sensor and fabric to be heated using an infrared heater or infrared radiation source.

[0083] In infrared radiation preheating technology, the preheating device typically includes an infrared heater, a reflector, and a control system. The infrared heater emits infrared light, while the reflector reflects and focuses the light to improve the heating effect. The control system monitors and regulates the preheating temperature to ensure temperature uniformity and stability.

[0084] Accurate preheating of graphene sensors and fabrics can be achieved by adjusting the power and preheating time of the infrared heater. During preheating, the system monitors the material temperature in real time and adjusts accordingly based on feedback to maintain a stable preset temperature.

[0085] In summary, infrared radiation-based preheating technology achieves a rapid, uniform, and efficient heating process by utilizing the energy transfer characteristics of infrared light. In applications such as the integration of graphene sensors with wearable fabrics, it can improve production efficiency, shorten preheating time, and ensure a good bond between the graphene sensor and the fabric.

[0090] Develop a software system based on image recognition and edge detection algorithms that can capture images of graphene sensors and fabrics in real time using a camera and accurately identify the position of the graphene sensors to ensure accurate alignment.

[0091] By applying a preset temperature and pressure using a heat transfer device and controlling the heat transfer time, the desired bonding strength between the graphene sensor and the fabric is ensured.

[0092] Develop heat transfer equipment with adjustable temperature and pressure, which can flexibly adjust temperature and pressure settings according to different graphene sensors and fabric materials to ensure a strong bond.

[0093] By introducing a feedback mechanism and control algorithm, the bonding degree between the graphene sensor and the fabric can be monitored in real time, and the temperature, pressure and heat transfer time can be automatically adjusted to achieve the ideal bonding effect.

[0094] These preferred implementations utilize machine vision, automation and control technologies, as well as adjustable thermal transfer equipment, to achieve an efficient, accurate, and flexible bonding process between graphene sensors and fabrics, ensuring that the bonding quality meets requirements.

[0095] S106, the cooled wearable fabric, allows the graphene sensor to be fully integrated with the fabric and ensures that the sensor element can measure and detect the required parameters;

[0096] Specifically, the following is a preferred implementation method:

[0097] Rapid cooling technology is used: Rapid cooling technology is employed to reduce the temperature of the graphene sensor and the fabric to promote solidification and curing during the bonding process. For example, methods such as using cooling devices, cold air, or liquid coolants can be used to rapidly reduce the temperature and accelerate the bonding speed of graphene to the fabric.

[0098] Utilizing low-temperature adhesives: Low-temperature adhesives are introduced to facilitate the bonding of graphene sensors to fabrics. These adhesives cure at lower temperatures, providing additional adhesion and stability during the bonding process, ensuring complete bonding of the graphene sensor to the fabric.

[0099] Combining physical and chemical crosslinking: Utilizing physical and chemical crosslinking methods to enhance the bonding between graphene sensors and fabrics. For example, using nanoparticles or crosslinking agents to enhance the interaction between graphene and fabric to increase bonding strength and stability.

[0100] Applying external pressure: During the cooling process, apply appropriate external pressure to promote the bonding between the graphene sensor and the fabric. Devices such as presses, rollers, or electromagnetic pressure can be used to ensure a tight bond between the graphene sensor and the fabric, optimizing the measurement and detection performance of the sensor element.

[0101] Post-cooling processing: After cooling, certain post-processing steps are performed to enhance the bonding between the graphene sensor and the fabric. For example, methods such as thermal annealing, photo-irradiation, or plasma treatment can be used to improve bonding strength and stability, and ensure that the sensor element can stably measure and detect the required parameters.

[0102] These preferred implementations can effectively facilitate the integration of graphene sensors with fabrics, ensuring that the sensor elements are fully integrated with the fabric and providing accurate parameter measurements and detection results.

[0107] 3. Biological Testing: For biological parameter sensors, biological testing can be performed to verify their measurement and detection performance. For example, quality control experiments can be conducted on biological parameter sensors, comparing them with standard instruments or methods, and verifying their accuracy and sensitivity by comparing them with known biological parameters.

[0108] 4. Multifunctional test platform: A well-designed multifunctional test platform can be used to test different parameters and evaluate the various functional performances of graphene sensors, such as temperature detection, pressure detection, and humidity detection.

[0109] 5. Field Testing: Apply the transferred graphene sensors to real-world environments or practical applications to evaluate their performance and reliability. By testing and comparing the sensor's measurement results in real-world scenarios, its applicability and reliability can be verified.

[0110] 6. Data Analysis and Processing: Conduct detailed analysis and processing of sensor test data, using statistical and machine learning methods to determine the accuracy, sensitivity, and stability of the sensors, and provide relevant verification reports and data support.

[0111] These methods effectively verify the proper functioning of transferred graphene sensors, evaluate their measurement and detection performance, and provide accurate and reliable results. By employing multiple detection methods and comprehensive analysis, the operational quality of graphene sensors can be ensured, providing reliable data support for their applications.
