Description

Technical Field

[0001] This invention relates to the fields of nuclear science and technology applications and mobile terminal display and structural design, and in particular to a biomimetic smartphone integrated system based on a nuclear battery. Background Technology

[0002] With the rapid development of mobile internet, mobile phones have become an indispensable tool in people's lives. Their functions are becoming increasingly rich, but power consumption is also increasing, and battery life has become a core bottleneck restricting the user experience. Current mobile phones mainly use lithium batteries as their energy source, but they have drawbacks such as short battery life, the need for frequent charging, and limited cycle life. In addition, discarded lithium batteries also pose a risk of environmental pollution.

[0003] Nuclear batteries, as a device that generates energy based on the decay of radioactive isotopes, have significant advantages such as high energy density, extremely long battery life, no need for frequent charging, and strong environmental adaptability. In theory, they can completely solve the problem of mobile phone battery life.

[0004] There are various types of nuclear batteries available, each with its own advantages and disadvantages: Tritium batteries have extremely low power density (only 0.01 mW / cm³-0.1 mW / cm³), requiring a large size to meet the peak load of mobile phones, and have a low battery life ceiling and poor energy conversion efficiency; Alpha decay nuclear batteries such as Plutonium-238 and Americium-241 are highly radiotoxic, and leaks can cause fatal harm to the human body, and require thick shielding layers, leading to uncontrolled size and weight, and are also subject to strict international regulations, making them completely unfeasible for civilian use; Gamma decay nuclear batteries such as Cobalt-60 and Cesium-137 have extremely strong radiation penetrating power, making it impossible for mobile phones to achieve lightweight and effective protection, and have short half-lives and high heat generation, failing to meet safety and practicality standards. From the perspective of energy conversion methods, thermoelectric nuclear batteries are complex and bulky, have slow response speeds, and suffer from significant heat dissipation issues; radiation-volt-effect nuclear batteries without carbon-14 radioactive sources are prone to semiconductor aging, low power density, and large voltage fluctuations; electrochemical nuclear batteries have problems such as electrolyte leakage risks, short lifespans, and low-temperature failures. These nuclear batteries, whether due to insufficient power, excessive size, high radiation risks and difficult protection, high cost, or poor environmental adaptability, cannot meet the core requirements of mobile phones for miniaturization, low radiation, high safety, and adaptability to instantaneous power consumption.

[0005] Therefore, nuclear batteries using carbon-14 as a radioactive source have become a more suitable choice for mobile phone applications. However, the application of nuclear batteries using carbon-14 as a radioactive source in miniaturized mobile terminals also faces many challenges: First, the beta rays emitted by the radioactive source pose a risk of leakage and may harm human health. Although the beta rays emitted have weak penetrating power, they can produce secondary bremsstrahlung radiation, and there is no mature solution for their protection. Second, nuclear battery phones may be exposed to drops, pressure, and extreme temperatures during use, which can easily lead to battery damage and leakage of radioactive materials. There is no mature solution for their safety. Third, real-time radiation monitoring and heat dissipation control of nuclear batteries have not yet been integrated with mobile phones and need to meet the relevant safety standards of the International Atomic Energy Agency. Finally, traditional mobile phone materials are difficult to balance the requirements of lightweight, high strength, impact resistance, and efficient heat dissipation. Nuclear battery phones, due to the need for a safety protection structure, further exacerbate the conflict between weight and performance.

[0006] At the same time, existing smartphones also have some inherent defects: as the largest power consumption unit of the whole device, the screen cannot achieve both lossless visual experience and extreme power consumption reduction with existing optimization methods, and there is also the problem of local aging and screen burn-in of OLED panels; the body materials can never meet the multiple requirements of lightweight, high strength and high thermal conductivity at the same time; the whole device is only adapted to the basic control logic of conventional lithium batteries, lacking a full-link collaborative intelligent control system and high-level safety protection architecture, and cannot adapt to the civilian application requirements of new isotope power supply systems. Summary of the Invention

[0007] Purpose of the invention: The purpose of this invention is to provide a biomimetic smartphone integrated system based on a nuclear battery. Through a carbon-14 powered smartphone intelligent nuclear energy system, a low-power smartphone screen that mimics the visual characteristics of the human retina, and a high-performance composite smartphone shell with a nacreous structure, this invention improves and innovates existing smartphones from three dimensions: energy supply, display optimization, and structural upgrade. It not only breaks the battery life ceiling of mobile terminals but also constructs a multi-level, full-chain nuclear safety protection system.

[0008] Technical solution: The biomimetic smartphone integrated system based on a nuclear battery provided by this invention includes: Smart phone nuclear energy system; bionic phone screen; bionic phone casing; and AI intelligent control module deployed on NPU chip; The mobile phone intelligent nuclear energy system includes a mobile phone body and a nuclear battery module and a radiation shielding system installed on the mobile phone body; The nuclear battery module uses carbon-14 as a radioactive source and converts the beta rays released by its beta decay into electrical energy through the beta-voltaic effect. Its transducer unit uses a wide bandgap topological semiconductor material. The radiation shielding system includes: The inner shielding layer of the nuclear battery module is wrapped with a wide bandgap topological semiconductor thin film that is the same as the transducer unit of the nuclear battery module. An outer shielding layer that suppresses trace amounts of secondary bremsstrahlung generated by the inner shielding layer; A titanium alloy leak-proof container filled with inert gas to achieve complete sealing and isolation of radioactive materials; The bionic mobile phone screen adopts a gaze-point dynamic partition rendering architecture based on the visual characteristics of the fovea of ​​the human eye's retina, achieving adaptive optimization of display power consumption. The bionic mobile phone shell adopts a three-layer composite structure that mimics the pearl layer of a seashell, including an inner bionic pearl layer, a middle carbon fiber reinforced epoxy resin layer, and an outer bionic lotus leaf hydrophobic coating. The AI ​​intelligent control module communicates and links with the mobile phone intelligent nuclear energy system, the bionic mobile phone screen, and the bionic mobile phone shell across the entire chain, realizing integrated intelligent control of the whole machine's energy supply, power consumption optimization, and safety management.

[0009] Furthermore, the mobile phone intelligent nuclear energy system also includes an impact-resistant and high-temperature resistant protective shell, a built-in buffer layer, and an emergency isolation device; The impact-resistant and high-temperature-resistant protective shell is made of carbon fiber reinforced composite material and wraps the radiation shielding system. The built-in buffer layer is a silicone rubber buffer pad, which is respectively located between the nuclear battery module and the inner shielding layer, and between the radiation shielding system and the impact-resistant and high-temperature protective shell. The emergency isolation device includes a pressure sensor, a control chip, and a polymer gel storage chamber. The pressure sensor is embedded in the inner wall of the titanium alloy leak-proof container, and its diaphragm is in contact with the inert gas. When a pressure surge is detected that exceeds a preset threshold, the control chip drives the polymer gel storage chamber to release gel, thereby achieving immediate sealing of the leak point.

[0010] Furthermore, the mobile phone intelligent nuclear energy system also includes a real-time monitoring and feedback module, with a built-in radiation sensor and a user interface prompt unit integrated into the mobile phone operating system; the radiation sensor is installed on the outer wall of the titanium alloy leak-proof container to monitor the radiation leakage status in real time, and the user interface prompt unit displays the radiation safety status through graded indicators. When the radiation dose exceeds the preset safety threshold, a graded audible and visual alarm is triggered, and when the dose continues to exceed the standard, a forced shutdown procedure is initiated.

[0011] Furthermore, the mobile phone intelligent nuclear energy system also includes an integrated heat dissipation and energy management module, including a high-efficiency heat dissipation module, an energy regulation circuit, and a supercapacitor energy storage module; The high-efficiency heat dissipation module includes an ultra-thin heat dissipation plate, a graphene composite heat dissipation film, directional heat dissipation ribs, and a thermal isolation buffer layer. The ultra-thin heat dissipation plate is closely attached to the outer wall of the titanium alloy leak-proof container to achieve uniform heat dissipation. The graphene composite heat dissipation film conducts heat in a directional manner along the arrangement direction of the middle carbon fiber reinforced epoxy resin layer. The directional heat dissipation ribs are consistent with the heat dissipation direction of the middle carbon fiber layer. The thermal isolation buffer layer is made of ceramic fiber material and is set between the radiation shielding system and the mobile phone electronic components. The supercapacitor energy storage module uses a graphene-carbon nanotube composite supercapacitor, which works in conjunction with the nuclear battery module and energy regulation circuit to compensate for the insufficient instantaneous power output of the nuclear battery.

[0012] Furthermore, the AI ​​intelligent control module incorporates a user behavior recognition model, a radiation safety early warning model, and a whole-machine power consumption adaptation model. The user behavior recognition model dynamically adjusts the supercapacitor charging and discharging strategy by learning the user's high power consumption periods and the power consumption characteristics of the APP. The radiation safety early warning model analyzes radiation sensor sampling data based on the LSTM time series algorithm, establishes a baseline for normal fluctuations in radiation dose, and provides early warning of the risk of aging and leakage of the shielding layer. The overall power consumption adaptation model monitors the power consumption of the phone's CPU and GPU in real time, triggers the supercapacitor to discharge in advance during periods of high instantaneous load, and reduces the output power of the core battery during periods of low load.

[0013] Furthermore, the bionic mobile phone screen adopts a partitioned LTPO flexible OLED panel, which is divided into a dynamically variable central gaze rendering area and an edge low-power rendering area; it is equipped with a micro gaze tracking module integrated on the same substrate as the front camera module, and an AI gaze point rendering algorithm deployed on the NPU chip; the AI ​​gaze point rendering algorithm has a built-in eye movement trajectory prediction model based on LSTM+optical flow method, which dynamically adjusts the position, area and display parameters of the central gaze rendering area based on the user's gaze point coordinates, and at the same time identifies the usage scenario to adaptively optimize the rendering strategy, reducing display power consumption without perceptibly losing the core visual experience.

[0014] Furthermore, the bionic mobile phone screen incorporates an OLED partition aging equalization algorithm to monitor the illumination time and brightness decay of pixels in each area of ​​the panel in real time. Through pixel brightness compensation, full-screen load balancing, and pixel dynamic offset technology, it balances the aging speed of each area of ​​the screen and reduces the risk of screen burn-in. The real-time power consumption data of the bionic mobile phone screen is synchronized to the AI ​​intelligent control module and the integrated heat dissipation and energy management module to achieve dedicated linkage and adaptation between screen rendering power consumption and power supply strategy.

[0015] Furthermore, the inner layer of the biomimetic mobile phone shell is a biomimetic pearl layer, which is composed of calcium carbonate nanosheets modified with aminosilane coupling agent and organosilicon modified epoxy resin. It absorbs impact energy through the interlayer slip effect of nanosheets. The middle layer is a carbon fiber reinforced epoxy resin layer, with the carbon fibers arranged unidirectionally along the heat dissipation direction of the mobile phone, taking into account both structural rigidity and directional thermal conductivity. The outer layer is a biomimetic lotus leaf hydrophobic coating, which is prepared using a microporous polydimethylsiloxane micro-nano structure, and has both superhydrophobic and anti-fouling properties and low thermal resistance characteristics.

[0016] Beneficial effects: Compared with the prior art, the significant advantages of this invention are: The miniaturized nuclear battery module using carbon-14 as a radioactive source generates long-term stable electrical energy through the voltaic effect of β decay. At the same time, it utilizes the characteristics of topological semiconductors to improve battery power, which is suitable for mobile phone usage scenarios. It fundamentally solves the industry pain points of traditional lithium batteries, such as short battery life, frequent charging, limited cycle life, and the risk of heavy metal environmental pollution after disposal. In addition, it innovatively introduces a bionic mobile phone screen designed based on the visual characteristics of the human fovea. With the help of AI gaze-point dynamic partition rendering technology, it significantly reduces display power consumption without imperceptibly affecting the user's core visual experience. It forms a two-way closed loop with the nuclear battery power supply system of "continuous energy supply + extreme optimization of terminal power consumption", which further reduces the continuous output pressure of the nuclear battery, extends the service life of core components, and breaks through the battery life ceiling of mobile terminals. This invention constructs a multi-level nuclear safety protection system consisting of "layered radiation shielding + fully sealed inert gas encapsulation + impact-resistant physical protection + emergency leak sealing + real-time radiation monitoring," which comprehensively ensures the safety of use in civilian scenarios. All indicators meet the safety standards for civilian radioactive materials of the International Atomic Energy Agency. The power consumption optimization of the bionic screen also reduces the heat generation of the whole machine, alleviates the working pressure of the heat dissipation system, reduces the temperature fluctuation of the nuclear battery working environment, and further improves the safety and stability of the whole machine in long-term operation. Meanwhile, this invention breaks through the performance bottleneck of traditional mobile phone materials that cannot simultaneously achieve "lightweight, high strength, and high heat dissipation". It constructs a unified bionic design system for the whole device. The three-layer composite structure of the bionic shell has high impact resistance, excellent structural rigidity, and efficient directional heat conduction performance. The bionic mobile phone screen and shell design form a complete system. It adopts an ultra-thin flexible substrate and an integrated heat dissipation design to effectively control the weight of the whole device and fully meet the portability requirements of consumer mobile phones. This invention is based on a full-link AI intelligent control system built on a mobile phone NPU chip. It can dynamically optimize the charging and discharging strategy of supercapacitors, provide early warning of shielding layer aging risks 3 days in advance based on LSTM algorithm, and optimize energy output by matching CPU / GPU power consumption in real time. It effectively solves the pain point of insufficient instantaneous power of nuclear batteries. It also deeply integrates the rendering algorithm of bionic screen, realizing intelligent management of energy distribution, safety warning, device adaptation, and display optimization in all dimensions. The core components are all compatible with the existing consumer electronics mass production system, and the mass production transformation cost is controllable. While achieving ultra-long battery life and high-level safety protection, it is fully compatible with the functional requirements and user habits of existing smartphones, and has excellent environmental protection and broad prospects for civilian market applications.

[0017] Figure 1 This is a schematic diagram of the integrated structure of the bionic smartphone system of the present invention; Figure 2 This is a cross-sectional view of the nuclear battery module and radiation shielding system of the present invention; Figure 3 This is a schematic diagram of the principle of the present invention. Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3 The biomimetic smartphone integration system based on a nuclear battery, as shown, includes: Smart phone nuclear energy system; bionic phone screen; bionic phone casing; and AI intelligent control module deployed on NPU chip.

[0020] The mobile phone intelligent nuclear energy system includes a mobile phone body 1, a nuclear battery module 2 and a radiation shielding system 3 located on the mobile phone body 1; the mobile phone body 1 adopts a conventional smartphone shape design, and the layout of core components strictly follows the principles of thinness and lightness. The nuclear battery module 2, as the core power supply unit, is located in the central area of ​​the back of the mobile phone body. By optimizing the packaging structure, the weight is controlled to within 20g. With the addition of a three-layer biomimetic composite shell, the overall weight of the mobile phone does not exceed 200g, which fully meets the requirements for portable use.

[0021] Nuclear battery module 2 uses high-purity carbon-14 as the β-radiation source, converting the high-energy β electrons generated by its decay into electrical energy through the Beta-Volta effect. The carbon-14 lattice is doped into porous, wide-bandgap topological semiconductor transducer units, such as niobium phosphide (NbP), tantalum arsenide (TaAs), and silicon carbide-based topological heterojunctions, to achieve zero-distance coupling between the radiation source and the transducer unit, reducing the energy loss of β particles during flight. This material, relying on its topologically protected, backscatter-free ballistic transport characteristics, constructs low-loss carrier transport channels, significantly suppressing electron-hole pairs excited by β particles. The reduction of recombination losses during transport significantly improves carrier collection efficiency and energy conversion efficiency. The battery's output power density is primarily determined by short-circuit current density and open-circuit voltage. Improved carrier collection efficiency directly increases short-circuit current density, which, combined with the inherently high open-circuit voltage of the wide-bandgap semiconductor, synergistically enhances output power density. Simultaneously, the intrinsic radiation robustness of the topological semiconductor effectively mitigates semiconductor lattice damage and performance degradation caused by long-term β-irradiation, ensuring long-term stable battery operation and meeting the continuous power supply needs of smartphones. A miniaturized hermetically sealed package design ensures stable energy output and a compact structure.

[0022] Radiation shielding system 3 includes: The inner shielding layer 4 of the nuclear battery module 2 is wrapped with a wide bandgap topological semiconductor thin film of the same origin as the transducer unit of the nuclear battery module 2; the outer shielding layer 5 suppresses the trace secondary bremsstrahlung generated by the inner shielding layer 4; and the titanium alloy leak-proof container 6 is filled with inert gas 18 to achieve full-sealed isolation of radioactive materials.

[0023] The radiation shielding system 3 adopts a composite protection scheme of "integrated transducer-shield layered shielding + fully sealed encapsulation"; the inner layer is an integrated transducer-shield inner shielding layer 4, which uses a silicon carbide-based topological semiconductor ultrathin film of the same origin as the transducer unit of the nuclear battery module 2, with a thickness controlled between 50μm and 120μm, to encapsulate the nuclear battery module 2. With radiation protection as its core priority function, while effectively blocking carbon-14 β rays, it can perform secondary beta-voltaic transduction on backscattered and laterally escaping β particles that were not captured by the main transducer unit, thus converting the original... The shielding material absorbs and converts the kinetic energy of β particles into waste heat, which is then converted into electrical energy and fed into the overall power supply chain. At the same time, the kinetic energy of β particles is completely exhausted during the energy conversion process, thus providing a radiation shielding effect. The middle layer is the outer shielding layer 5, which effectively suppresses the trace secondary bremsstrahlung radiation generated by the inner shielding layer 4. The outer layer is a 1.2mm thick titanium alloy leak-proof container 6, which is filled with high-purity inert gases 18 such as argon, nitrogen, and helium. The container interface is seamlessly sealed by laser welding, thus completely eliminating the risk of radioactive material leakage from the structure.

[0024] It also includes safety protection mechanisms to further enhance the safety of the equipment in all scenarios, including an impact-resistant and high-temperature resistant protective shell 8, an internal buffer layer 9, and an emergency isolation device. The impact-resistant and high-temperature resistant protective shell 8 is made of carbon fiber reinforced composite material with a tensile strength ≥1500MPa and a heat resistance temperature ≥200℃, completely enclosing the radiation shielding system 3; the internal buffer layer 9 uses silicone rubber buffer pads with a Shore hardness of 50, which are respectively placed between the nuclear battery module 2 and the inner shielding layer 4, and between the radiation shielding system 3 and the impact-resistant and high-temperature resistant protective shell 8. The buffer pads have a 1mm heat dissipation gap, which can effectively absorb the impact force generated by drops and compression without hindering heat conduction; the emergency isolation device is equipped with an MPX10 pressure sensor 11 and an STM32F103 microcontroller. The control chip and polymer gel storage cavity 12 are filled with instant-drying organosilicon thixotropic gel, such as single-component de-alcoholized fast-curing RTV organosilicon thixotropic gel, siloxane-nano silica hybrid radiation-resistant thixotropic gel, microencapsulated addition-type instant-drying organosilicon thixotropic gel, etc. The pressure sensor 11 is embedded in the groove of the inner wall of the titanium alloy leak-proof container 6. Its diaphragm is in direct contact with the internal inert gas 18. When a pressure change is detected to exceed the preset threshold (±0.1MPa), the control chip drives the micro solenoid valve to open within 50ms. The annularly arranged polymer gel storage cavity 12 quickly releases the gel to achieve immediate sealing of the leak point.

[0025] It also includes a real-time monitoring and feedback module to achieve full visualization and control of the radiation status: the built-in radiation sensor 13 uses a miniature Geiger counter GM-100, installed on the outer wall of the titanium alloy leak-proof container 6, with a detection range of 0.01-100μSv / h and a sampling frequency of 1 time / second, communicating with the mobile phone motherboard in real time via the I2C bus; the user interface prompt unit is deeply integrated into the mobile phone operating system, adding a dedicated "radiation safety" function module, which intuitively displays the radiation safety status with green (radiation dose <0.5μSv / h), yellow (0.5μSv / h-1μSv / h), and red (≥1μSv / h) icons. The module stores detailed emergency handling guidelines for users to refer to; when the radiation dose enters the yellow warning zone, the mobile phone triggers a vibration alarm; when it enters the red over-limit zone, a continuous audible and visual alarm is immediately activated, and a forced shutdown procedure is automatically executed after 10 seconds to maximize user safety.

[0026] It also includes an integrated heat dissipation and energy management module that balances equipment operation stability and power supply reliability, including a high-efficiency heat dissipation module 15, an energy regulation circuit 16, and a supercapacitor energy storage module 17. The high-efficiency heat dissipation module 15 adopts an integrated directional heat dissipation system with a total thickness controlled at 1.8mm. The ultra-thin heat dissipation plate is tightly attached to the outer wall of the titanium alloy leak-proof container 6 to achieve uniform heat dissipation. The graphene composite heat dissipation film conducts heat in a directional manner along the arrangement direction of the carbon fiber reinforced epoxy resin layer in the middle layer of the biomimetic mobile phone shell. The directional heat dissipation ribs are consistent with the heat dissipation direction of the middle carbon fiber layer, accelerating the dissipation of heat to the shell. The thermal isolation buffer layer is made of ceramic fiber material with a thermal conductivity of ≤0.1W / (m・K) and is set between the radiation shielding system 3 and electronic components such as the mobile phone motherboard and display screen, effectively blocking the coupling of heat sources and avoiding the superposition of temperature rise. The energy regulation circuit 16 uses an LDO-7805 voltage regulator chip, paired with a π-type filter network (100μF capacitor + 10μH inductor + 10μF capacitor) and a 1000μF tantalum capacitor. The output voltage is stable at 4.2V, and the current fluctuation is controlled within ±5%, accurately matching the power supply requirements of various components of the mobile phone. The supercapacitor energy storage module 17 uses a graphene-carbon nanotube composite supercapacitor, configured in three parallel groups. Each group of capacitors has a specification of 5000mF / 5.5V, with a total capacity of 15000mF. It is paired with a 1000μF tantalum capacitor to form a "main-auxiliary" energy storage architecture. The supercapacitor adopts a thin stacked design with a single group thickness of 1.0mm, which is tightly fitted to the energy regulation circuit 16. It works in conjunction with the nuclear battery module 2 and the energy regulation circuit 16. Its volumetric energy density reaches 85Wh / L, power density reaches 12kW / kg, and charge and discharge response time is ≤1ms, which can quickly compensate for the instantaneous power deficiency of the nuclear battery.

[0027] The AI ​​intelligent control module incorporates a user behavior recognition model, a radiation safety early warning model, and a whole-device power consumption adaptation model. Deployed in the phone's NPU chip, the AI ​​intelligent control module achieves intelligent control of energy allocation, safety warnings, and device adaptation through algorithm optimization. Regarding energy allocation, the user behavior recognition model is pre-trained. By collecting user usage data over 30 days, it learns the power consumption characteristics of high-power periods (such as commuting hours and lunch break entertainment times) and frequently used apps, dynamically adjusting the charging strategy of the supercapacitor energy storage module 17. One hour before peak load, the energy regulation circuit 16 increases the charging efficiency of the nuclear battery to the supercapacitor energy storage module 17 from the conventional 70% to 90%, achieving rapid energy replenishment. During low-load periods (such as at night...)... In standby mode, the charging efficiency is reduced to 50% to reduce energy loss. In terms of safety warning, based on the LSTM time series algorithm, the continuous sampling data of the radiation sensor 13 is analyzed to establish a baseline for normal fluctuations in radiation dose. When a slow upward trend in radiation dose caused by the aging of the radiation shielding layer 3 is detected, a warning is issued through the user interface 3 days in advance to remind the user to perform maintenance. In terms of device adaptation, the power consumption changes of the CPU and GPU are monitored in real time. When a momentary high load is detected (such as starting a large game or shooting 4K video), the supercapacitor is triggered to discharge 0.5ms in advance to avoid voltage fluctuations affecting the user experience. During low load periods, the output power of the nuclear battery is automatically reduced to extend the service life of the nuclear battery module 2 and related components.

[0028] The nuclear battery module 2 continuously generates electricity through carbon-14 decay. After being regulated and filtered by the energy regulation circuit 16, it provides stable power to the various electronic components of the mobile phone and charges the supercapacitor energy storage module 17. The AI ​​intelligent control module analyzes user behavior and device power consumption in real time, dynamically optimizing charging efficiency and energy distribution strategies. The high-efficiency heat dissipation module 15 continuously conducts the heat generated by the nuclear battery module 2 to the outer casing for dissipation, and the thermal insulation layer ensures that other components are not affected by temperature rise. The radiation sensor 13 monitors the radiation status throughout the process and provides real-time feedback through the user interface. In case of accidents such as drops or crushing, the built-in buffer layer 9 absorbs the impact force. If the titanium alloy container is damaged, the pressure sensor 11 immediately captures the signal, and the polymer gel storage cavity quickly releases gel to seal the leak point. At the same time, the radiation sensor 13 detects excessive radiation and triggers corresponding alarms and forced shutdown procedures, ensuring the safe and stable operation of the equipment in all aspects. The bionic phone screen is designed based on the foveal visual characteristics of the human eye. It uses a 6.7-inch LTPO flexible OLED panel with a total thickness of 1.0mm, which is installed in close contact with the front structure of the phone. The effective display size of the panel matches the overall structure of the phone. A 0.08mm thick ultra-thin graphene heat dissipation film is attached to the back of the panel, which is connected to the heat dissipation direction of the carbon fiber reinforced epoxy resin layer in the middle layer of the phone. It is integrated into the overall directional heat dissipation system of the whole machine, ensuring that the heat generated by the screen is quickly conducted to the shell and dissipated, without forming a temperature rise coupling and superposition with the heat source of the nuclear battery. The outer protective layer of the screen adopts a microporous PDMS micro-nano structure bionic lotus leaf hydrophobic coating with the same origin as the outer layer of the main body of the phone (bionic phone shell). The coating thickness is 60μm, which achieves a super hydrophobic and anti-fouling effect with a water contact angle of ≥150°, and forms a unity with the overall bionic design system of the phone.

[0029] The bionic mobile phone screen adopts a dynamic dual-zone rendering architecture, with the panel divided into a central gaze rendering area and an edge low-power rendering area: the central gaze rendering area is a dynamically variable area that covers 5% of the display area in the center of the screen by default, and supports retina-level high-definition display with a maximum resolution of 3200×1440 and an adaptive refresh rate of 1Hz-120Hz; the edge low-power rendering area is a ring-shaped display area outside the central area, with a resolution adjustment range of 720P-1080P and a refresh rate that is dynamically adjusted synchronously from 30Hz-120Hz.

[0030] The integrated miniature eye-tracking module is designed to be integrated with the front-facing punch-hole camera module of the mobile phone on the same substrate. It consists of two miniature infrared fill lights and one 1.3-megapixel infrared camera. The total thickness of the module is controlled within 1.2mm, the sampling frequency is 120Hz, the eye-tracking positioning accuracy is ≤0.5°, and the eye movement capture latency is ≤8ms. It communicates with the mobile phone motherboard and NPU chip in real time through the MIPI interface. The infrared fill lights adopt a pulse lighting mode synchronized with the sampling frequency, with a single lighting duration of 5μs, which reduces power consumption by 60% compared to the constant lighting mode. The module can stably capture the coordinates of the user's gaze point in all scenarios, including strong light, backlight, and low light, and is compatible with the use scenarios of conventional mobile phone accessories such as thick tempered glass screen protectors and privacy screen protectors.

[0031] The AI ​​gaze-tracking rendering algorithm is deeply deployed in the phone's NPU chip and fully integrated with the existing AI intelligent control module. The algorithm incorporates an eye movement trajectory prediction model based on LSTM and optical flow. Based on real-time coordinates of the user's gaze point collected by the eye-tracking module, it dynamically adjusts the position and area of ​​the central gaze rendering area within 5ms, eliminating image quality stuttering during rapid scanning and screen switching. By learning the user's usage habits over the past 30 days, the algorithm adaptively matches scene-specific rendering strategies—in reading scenarios, the central rendering area shrinks to 5%, maintaining high definition only in the text gaze area, while the resolution of edge areas is reduced to 720P and refresh rate. The refresh rate is reduced to 30Hz. In gaming scenarios, the central rendering area automatically expands to 15% while maintaining a 120Hz high refresh rate, while the edge areas are reduced to 1080P and 60Hz. In video playback scenarios, the central rendering area covers the entire screen, with only the black border area reduced to low-power mode. The algorithm also supports multi-person gaze detection. When two or more faces and gaze points are detected in front of the screen, it automatically switches to full-area retina-level high-definition mode and automatically switches back to low-power mode after single-person use. The system also adds a customizable edge area function, allowing users to mark the game minimap, notification bar, and bullet screen area as permanent high-definition reserved areas, while also taking into account the needs of peripheral vision information recognition.

[0032] The bionic mobile phone screen, along with the overall heat dissipation and energy management module and the AI ​​intelligent control module, achieves full-link collaborative operation: the screen's real-time power consumption data is synchronously transmitted to the heat dissipation and energy management module via the motherboard. Based on changes in screen power consumption, the AI ​​intelligent control module dynamically optimizes the output power of the core battery module and the charging and discharging strategy of the supercapacitor energy storage module. When high-load display scenarios such as starting a large game or shooting 4K video are detected, the supercapacitor is pre-discharged 0.5ms in advance to avoid voltage fluctuations caused by high screen power consumption. When the screen is off, in standby mode, or under low load display scenarios are detected, the eye-tracking module synchronously enters a low-power mode, the infrared fill light is turned off, the camera sampling frequency is reduced to 10Hz, and the module power consumption is reduced by 80%. At the same time, the system further reduces the power consumption of the entire screen area, synchronously reduces the output power of the core battery, reduces energy loss, and extends the service life of the core battery module 2 and related components.

[0033] The bionic mobile phone screen incorporates an OLED zone aging balance algorithm deployed in the phone's NPU chip. This algorithm can monitor the pixel illumination time and brightness decay data of each area of ​​the panel in real time. It performs micro-brightness compensation of ≤5% for the central rendering area that has been working under high load for a long time. It automatically triggers a full-screen pixel refresh to balance the load every 7 days. At the same time, the central rendering area adopts pixel dynamic offset technology to avoid fixed area pixels working under high load for a long time, which greatly reduces the risk of OLED burn-in, ensures that the aging speed of each area of ​​the screen tends to be consistent, and extends the service life of the entire device.

[0034] The bionic mobile phone screen in this embodiment can achieve a net reduction of 40%-55% in overall screen power consumption across all scenarios without sacrificing the user's core visual experience. It directly reduces the energy consumption of the largest power consumption unit in the whole device, and forms deep synergy with the mobile phone's smart nuclear energy system and AI intelligent control system, further strengthening the core advantage of the mobile phone's ultra-long battery life. At the same time, it continues the core invention idea of ​​the whole device's bionic design, forming a complete bionic structural design system with the bionic mobile phone shell 1.

[0035] The mobile phone casing of this embodiment adopts an innovative three-layer biomimetic composite structure, including an inner biomimetic pearl layer, a middle carbon fiber reinforced epoxy resin layer, and an outer biomimetic lotus leaf hydrophobic coating, comprehensively taking into account protection, heat dissipation, and practicality: The inner layer is a biomimetic pearl layer, made of calcium carbonate nanosheets modified with aminosilane coupling agent and organosilicon modified epoxy resin as raw materials. After molding, the thickness is controlled at 0.9mm, which can effectively absorb external impact energy and avoid interlayer delamination; The middle layer is a carbon fiber reinforced epoxy resin with a thickness strictly controlled at 1mm. The carbon fibers are unidirectionally arranged along the longitudinal direction of the mobile phone (i.e., the main direction of heat dissipation), which not only provides reliable structural rigidity support for the whole device, but also can quickly conduct the heat generated by the nuclear battery 2 to the casing 1; The outer layer is a biomimetic lotus leaf hydrophobic coating, which is prepared using a microporous PDMS micro-nano structure with a micropore diameter of about 3μm, a porosity of 30%, and a coating thickness of 60μm. While achieving superhydrophobic and anti-fouling effects, the microporous structure reduces thermal resistance and does not affect the overall heat dissipation efficiency of the device.
