[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] Before providing a detailed description of the embodiments of this application, some related technologies involved in the embodiments of this application will be described first, as follows:

[0039] Some related technologies:

[0040] 1. Development Trends of Wearable Devices: With the continuous advancement of technology, wearable devices are gradually becoming an indispensable part of people's lives and work. Smart gloves, as a type of wearable device, can realize multiple functions such as human-computer interaction, health monitoring, and rehabilitation assistance, and have broad application prospects.

[0041] 2. Advances in materials science: The development of new materials has made it possible to manufacture stretchable pressure sensors. For example, nanomaterials and conductive polymers have excellent conductivity and flexibility, which can meet the sensor performance requirements of smart gloves.

[0042] 3. Development of flexible electronics technology: The continuous maturation of flexible electronics technology enables sensors to better fit the human skin, improving wearing comfort and the accuracy of data collection.

[0043] 4. Medical rehabilitation needs: For patients with impaired hand function, such as those with nerve damage or arthritis, smart gloves can serve as a rehabilitation aid to help them restore hand function.

[0044] Other related technologies:

[0045] 1. Materials Innovation and Application Expansion:

[0046] (1) Background: In practical applications of stretchable pressure sensors, tensile deformation can interfere with pressure readings, leading to inaccurate measurements. For example, when a traditional capacitive pressure sensor is stretched, its capacitance change may not only be caused by pressure but also affected by tensile deformation, making it difficult to accurately distinguish the pressure signal. The performance of stretchable pressure sensors largely depends on the properties of the material, but traditional materials often cannot simultaneously meet the requirements of high sensitivity, high stability, and good flexibility.

[0047] (2) Existing technical solutions: Professor Lu Nanshu's team at UT-Austin developed a highly sensitive, intrinsically stretchable flexible composite response pressure sensor (SHRPS). This sensor uses conductive porous nanocomposite material (PNC) as the dielectric layer. Its working principle during in-plane stretching is similar to that of a traditional capacitive sensor. However, during out-of-plane compression, the change in PNC resistance causes the SHRPS to exhibit composite response characteristics, greatly enhancing its sensitivity to pressure changes while effectively reducing capacitive signal interference caused by stretching. Furthermore, researchers at Beijing Institute of Fashion Technology developed a capacitive pressure sensing fiber resistant to stretching interference. This fiber is formed by pre-stretching, twisting, coating, and shaping two elastic insulating tubes, then releasing the pre-stretching force to create a spiral structure, and introducing conductive material inside. When this spiral sensing fiber is stretched, only the helical pitch changes; the fiber structure itself is not stretched, thus the stretching has little impact on the pressure signal.

[0048] 2. Microstructure design and performance optimization:

[0049] (1) Background: The performance of stretchable pressure sensors can be further improved through microstructure design, but current research lacks a systematic exploration of the influence of structural parameters on performance.

[0050] (2) Existing technical solutions: Researchers improve the strain stability of stretchable pressure sensors by finely designing microstructural units, such as pyramid, cylindrical, and prismatic structures, to release strain. Furthermore, 3D printing technology provides new means for microstructural design. For example, porous structures manufactured through 3D printing can achieve precise perception and real-time response to minute physiological signals, complex motion states, and tactile changes in the environment. This synergistic optimization of microstructural design and 3D printing not only improves sensor performance but also makes it possible to achieve multifunctional integration, intelligent structural design, and large-scale fabrication.

[0051] To address the aforementioned shortcomings of existing technologies, this application aims to provide a smart glove system based on a stretchable bacterial pressure sensor to achieve the following objectives:

[0052] 1. Improved stability under bending and stretching: By programming the adhesive material with engineered bacteria, the sensor can maintain stable electrical signal transmission under bending and stretching conditions, thereby improving the accuracy of pressure measurement when the finger is bent.

[0053] 2. Enhanced sensor durability: The excellent mechanical properties of the engineered bacteria adhesion material enable the sensor to maintain stable operation even after multiple bending and stretching cycles, thus extending the sensor's service life.

[0054] 3. Simplified manufacturing process and reduced cost: The engineered bacteria adhesion material sensor used in this application has a relatively simple manufacturing process, which is easy to achieve large-scale production, thereby reducing manufacturing costs and ensuring product consistency and stability.

[0055] 4. Enhanced dynamic response capability: The sensor has a good response capability to rapidly changing pressure signals, and can capture and transmit accurate pressure data in real time, which is particularly suitable for tactile sensing in smart gloves.

[0056] Through the above improvements, the sensor of this application can maintain high signal stability during bending and stretching, and is particularly suitable for normal pressure detection on dynamic surfaces, such as tactile sensing of wearable gloves, ensuring accurate and reliable pressure measurement and meeting the application requirements of high-frequency finger joint movements.

[0076] The following section will provide a detailed introduction and explanation of the solutions in the embodiments of this application, using specific application examples.

[0077] This embodiment provides a stretchable pressure sensor based on an engineered bacterial adhesive material, aiming to solve the problems of sensitivity to bending and stretching in existing technologies. Through genetic engineering, proteins are expressed on the surface of bacteria, causing the bacteria to connect and adhere together, forming an engineered bacterial adhesive material, thus creating a stretchable bacterial pressure sensor. This stretchable bacterial pressure sensor can accurately detect the normal pressure of a fingertip, unaffected by finger joint bending. The principle behind the engineered bacterial adhesive material's pressure-sensing ability is that under pressure, the adhesive proteins of the adhered bacteria break, thus affecting the material's resistance. The magnitude of the pressure can be calculated from the resistance value. However, during stretching, the adhesive proteins have a certain strength, ensuring that the material's resistance remains unchanged under tension, thus the pressure detection is unaffected by stretching. Figure 1 As shown, Figure 1 The bacterial pressure sensor shown is made from engineered bacterial adhesive materials and is particularly suitable for fingertip tactile sensing in smart gloves.

[0078] 1. Structure of a smart glove based on a stretchable bacterial pressure sensor.

[0079] like Figure 2 and Figure 3 As shown, the structure of the smart glove with stretchable bacterial pressure sensors includes: a glove body, five stretchable bacterial pressure sensors extending from the finger joints on the back of the hand to the fingertips, a circuit board (PCB) integrating the various modules, a power supply, and a host computer (PC). The pressure sensors on the five fingers are connected to the circuit board (PCB) via wires.

[0080] 2. Bacterial pressure sensors for five fingers.

[0081] like Figure 2 As shown, the stretchable bacterial pressure sensor is fixed to the glove against the finger joint, and the engineered bacteria adhesive material is encapsulated in a flexible latex tube (this embodiment is not limited to using this type of tube), such as Figure 4 As shown.

[0082] The encapsulated engineered bacteria adhesive material possesses pressure-sensitive and tensile strength properties. The preparation of the engineered bacteria adhesive material involves the following steps:

[0083] (1) Preparation of bacterial suspension: First, take a small amount of bacterial strain from the culture and inoculate it into a suitable liquid culture medium. Then, incubate it in a constant temperature incubator at 30-35℃ for 18-24 hours. Next, transfer the revived bacterial strain to a new culture medium for subculture to obtain fresh culture. Finally, the bacterial suspension concentration can be determined by McFarland's turbidimetric method, absorbance method, or plate count method, and the concentration can be adjusted accordingly. The prepared bacterial suspension should be used immediately to ensure the activity of the bacterial suspension.

[0084] (2) Bacterial Collection: First, bacteria need to be cultured in a suitable culture medium to reach the logarithmic growth phase. This step usually requires culturing in a constant temperature incubator at 30-35℃ for 18-24 hours. Next, transfer the cultured bacterial solution to centrifuge tubes and select appropriate centrifugation conditions, generally 3000-5000 rpm for about 10 minutes, to allow the bacteria to precipitate. After centrifugation, carefully discard the supernatant, taking care not to disturb the bacterial precipitate. Then, for bacteria that need purification, resuspend the bacteria in sterile physiological saline or an appropriate buffer solution, and then centrifuge and wash again to remove residual culture medium components. Finally, transfer the collected bacterial precipitate to a new sterile container for subsequent experiments or storage. The entire process must be carried out under sterile conditions to avoid contamination.

[0085] 3. Circuit board (PCB).

[0086] The bacterial pressure sensors for the five fingers are connected to the PCB, which has three parts: a voltage acquisition and processing module, a microcontroller, and a wireless receiving module.

[0087] (1) Voltage Acquisition and Processing Module: The voltage acquisition and processing module adopts a voltage follower-type voltage divider circuit design, such as... Figure 5 As shown, this structure effectively and stably converts the resistance change generated by the pressure sensor under stress into a corresponding voltage change signal. This design not only simplifies the subsequent signal processing but also effectively avoids signal distortion caused by load effects, improving the system's response speed and measurement accuracy. Simultaneously, the high input impedance and low output impedance characteristics of the voltage follower ensure the stability and reliability of the sensor signal transmission, providing a precise voltage input for subsequent data acquisition and processing.

[0088] (2) Microcontroller: The main control chip of the system is the STM32 series microcontroller. This series of chips has stable performance, low power consumption, and abundant resources, making it suitable for embedded real-time control applications. The high-precision analog-to-digital converter (ADC) integrated inside the main control chip can quickly and accurately convert the analog voltage signal output by the voltage acquisition and processing module into digital signals. Subsequently, the main control chip performs real-time analysis and processing on the acquired digital signals, and accurately converts the voltage signal into the corresponding pressure value through the preset pressure-voltage mapping relationship. At the same time, combined with multiple channel inputs or multi-point recognition mechanisms, the system can effectively distinguish which finger the pressure signal comes from, realizing the functions of independent multi-finger recognition and multi-channel parallel detection, providing reliable data support for subsequent input recognition, gesture control, or human-computer interaction.

[0089] (3) Wireless Receiving Module: The pressure data processed by the microcontroller is transmitted to the host computer wirelessly. The BT08 low-power Bluetooth communication module is used as the core device for wireless transmission. The BT08 Bluetooth chip is compatible with the BLE (Bluetooth Low Energy) protocol and has the advantages of stable transmission, low power consumption, and small size, making it suitable for the data communication needs of portable and wearable devices. In practical applications, the microcontroller packages the processed pressure value and its source (such as the specific finger number) in a specific data format and communicates with the BT08 module via a serial port to achieve real-time data upload. After receiving the data from the Bluetooth module, the host computer can perform further decoding, visualization, or control logic response to ensure the stability, interactivity, and user experience of the system in actual use.

[0090] 4. Power supply module.

[0091] The power module uses a 3.3V lithium battery as its power source, providing stable and continuous power to the entire circuit board (PCB). Lithium batteries offer advantages such as high energy density, small size, light weight, and long cycle life, making them ideal for portable and wearable electronic devices. In the system design, a voltage regulator circuit or low-dropout regulator (LDO) ensures a stable output voltage of 3.3V, meeting the operating voltage requirements of core components such as the STM32 microcontroller, pressure sensor, voltage acquisition module, and Bluetooth communication module. Furthermore, the power module can be integrated with a battery management system (such as overcharge and over-discharge protection circuits) to enhance the safety and reliability of the device, providing a solid guarantee for the long-term stable operation of the entire system.

[0092] 5. Host computer.

[0093] To simultaneously acquire pressure signals from multiple fingers, the system employs a host computer (PC) for centralized communication with multiple sensors. Specifically, each of the five fingers is equipped with a bacterial pressure sensor. These sensors, via an integrated wireless communication module (such as the BT08 Bluetooth module), package the collected pressure data and send it to the host computer. The host computer is also equipped with a corresponding wireless communication module, establishing a stable two-way communication link to achieve real-time data reception and command issuance. This design not only reduces hardware redundancy and improves system integration and portability but also simplifies the communication architecture and data management process. Through channel identification and time series analysis of different sensor signals by the main control chip, the host computer can accurately identify the pressure data from each finger, achieving multi-point synchronous detection and intelligent interactive control functions.

[0094] In summary, this embodiment includes the following technical solutions:

[0095] 1. Improved stability under bending and stretching: By employing engineered microbial adhesion materials, the sensor maintains stable electrical signal transmission under bending and stretching conditions, thereby improving pressure measurement accuracy when the finger is bent. For example, Figure 6 This is a comparison of the output of a bacterial pressure sensor when low-voltage and high-voltage electrical signals are applied in straight and bent states, respectively.

[0096] 2. Enhanced sensor durability: The excellent mechanical properties of the engineered bacteria adhesion material enable the sensor to maintain stable operation even after multiple bending and stretching cycles, thus extending the sensor's service life.

[0097] 3. Simplified manufacturing process and reduced cost: The engineered bacteria adhesion material sensor used in this embodiment has a relatively simple manufacturing process, which is easy to achieve large-scale production, thereby reducing manufacturing costs and ensuring product consistency and stability.

[0098] 4. Enhanced dynamic response capability: The sensor has a good response capability to rapidly changing pressure signals, and can capture and transmit accurate pressure data in real time, which is particularly suitable for tactile sensing in smart gloves.

[0099] Through the above technical solution, the bacterial pressure sensor in this embodiment can maintain high signal stability during bending and stretching, and is particularly suitable for normal pressure detection on dynamic surfaces, such as tactile sensing of wearable gloves, ensuring accurate and reliable pressure measurement and meeting the application requirements of high-frequency finger joint movements.

[0100] Compared with the prior art, the beneficial effects of this embodiment include:

[0101] 1. Insensitive to bending and stretching:

[0102] The engineered bacterial adhesion material used in this embodiment maintains a stable electrical signal output under both bending and stretching conditions. This characteristic is particularly important for frequently moving joints, where sensors in existing technologies often experience signal drift or distortion due to bending or stretching, affecting measurement accuracy. This embodiment solves this problem, ensuring measurement stability and accuracy in complex dynamic environments.

[0103] 2. Excellent durability:

[0104] Thanks to the use of engineered microbial adhesion materials, the sensor in this embodiment maintains stable operation even after multiple bending and stretching cycles, significantly extending its lifespan. In contrast, sensor materials in existing technologies often experience performance degradation or damage after repeated stress cycles, affecting their long-term reliability.

[0105] 3. Simplify manufacturing processes and reduce costs:

[0106] The engineered bacterial adhesion material used in this embodiment has a relatively simple manufacturing process, making it easy to achieve large-scale production and reducing manufacturing costs. In contrast, existing sensors that rely on complex nanomaterials or conductive polymers have complex manufacturing processes and high costs, limiting their feasibility for large-scale application.
