In addition, the smart ring can also be seamlessly connected with smart devices such as mobile phones to realize a variety of practical functions such as notification reminders and smart control. In general, the AI smart ring is a perfect combination of modern technology and fashionable design, making smart life within reach.
Smart Ring Composition
Smart rings are usually made up of the following main parts:
1. Main chip and processor: The main chip and processor in a smart ring are responsible for controlling and processing various functions and data. They can vary depending on the design and requirements, but generally include components such as processors, memory and storage.
2. Sensors: Smart rings have multiple sensors built in to collect environmental information and user data. Common sensors include accelerometers, gyroscopes, heart rate monitors, temperature sensors, etc., which can capture finger movements, detect heart rate, measure temperature, etc. to provide various functions and data.
3. Display: Smart rings are usually equipped with a small display to display information such as time, notifications, and health data. The type and size of the display may vary, and common technologies include OLED and LCD.
4. Battery: To ensure that the smart ring can work properly, it usually has a small rechargeable battery integrated inside. The capacity and battery life of the battery vary depending on the power consumption of the device and the frequency of use.
5. Communication module: In order to achieve connection and data transmission with other devices, smart rings are often equipped with wireless communication modules such as Bluetooth and Wi-Fi. Through these communication modules, smart rings can synchronize data and remotely control other devices such as smartphones and computers.
6. Waterproof design: In order to meet the needs of users in daily life, many smart rings are also waterproof. This allows users to continue wearing and using smart rings when washing hands, taking a shower, etc.
In addition, smart rings may also have other functions and components, such as heart rate monitoring, GPS positioning, sound sensors, etc., depending on different brands and models. Overall, the composition of smart rings depends on their design, brand and positioning to meet the needs and expectations of users.
Soft-hard combination board solves the design problem of smart ring
The circuit board used is a circuit board with more than two layers, which is a combination of soft and hard. It includes multiple flexible circuit boards and multiple rigid circuit boards. The flexible circuit board is between two rigid circuit boards and connected to two adjacent rigid circuit boards. The rigid circuit board includes a processor and an optical PPG sensor, and the processor is connected to the optical PPG sensor. Some flexible circuit boards include resistors and capacitors.
By using more than two layers of soft-hard combination circuit boards to replace the single-layer circuit board design, the main components such as processors and sensors are placed on the rigid circuit board, and multiple rigid circuit boards are connected through flexible circuits. Resistors and capacitors can be set on some flexible circuit boards, making full use of the space inside the smart ring, placing more components, and realizing more functions. The combination of rigid circuit boards and flexible circuit boards makes it easier to fix in the installation cavity.
Functions of Smart Rings
Smart rings provide effective support in lifestyle and health management, thanks to the advanced technology embedded within each ring, typically including NFC chips, Bluetooth, sensors, and batteries.
Like any other medical technology, their design process involves extensive research and countless hours of development to ensure optimal results for users. Since rings may not fit everyone’s fingers perfectly, companies also face the challenge of tailoring device sizes accurately for each individual.
Most companies address this by offering sizing kits that help customers determine the right fit before purchase. Unlike smartphones and smartwatches, smart rings do not require constant charging. They can last several days without users worrying about battery depletion, making them an excellent choice for those who are frequently busy or traveling.
While smart rings provide numerous convenient lifestyle benefits, most people purchase them primarily for health and fitness purposes. These rings can monitor a wide range of health metrics, from sleep patterns to heart rate. Below are some of the health insights typically provided by smart rings.
Monitoring Stress Levels
Living in the modern world can significantly impact mental health. At times, stress may even lead to anxiety, making it essential to maintain a clear and calm mindset. Stress affects various physiological processes in the body, often as a result of the autonomic nervous system.
This can influence the skin’s electrical activity, or EDA, which smart rings use to track stress levels. Rings equipped with this feature transmit the information to smartphone apps, enabling users to monitor and manage their stress levels in real-time.
Tracking Sleep Patterns
Many people suffer from inadequate sleep due to illnesses or insomnia. Sleep problems can adversely affect mental health and daily life. However, wearing a smart ring can help monitor sleep patterns and keep track of daily rest.
Some smart rings provide crucial insights, such as the number of hours spent in deep, light, or REM sleep, helping users create better sleep logs. Others can detect sleep apnea events and measure blood oxygen saturation and heart rate.
Monitoring Blood Oxygen Levels
Maintaining stable blood oxygen levels is essential for normal bodily functions. Hypoxemia, a condition characterized by below-normal oxygen levels, can result from poor blood circulation in certain areas of the body. It can cause symptoms like headaches or shortness of breath, and in severe cases, it may disrupt brain and heart function.
Fortunately, some smart rings can provide data on blood oxygen levels, helping users detect early signs of hypoxemia and prevent further complications. These rings monitor body movement, heart rate, and oxygen saturation.
Tracking Heart Rate
For individuals with cardiovascular conditions, wearing a smart ring is an ideal way to monitor heart health. It allows users and doctors to detect irregularities and prevent potential complications.
Some smart rings feature accelerometers and heart rate monitors that transmit essential data to smartphone apps. Others utilize PPG signals to detect atrial fibrillation or similar symptoms.
8 self-protection functions
1. Input power limit protection
When the power of the battery board is greater than the rated power, the controller will limit the power of the battery board within the rated power to prevent the current from being too large to damage the controller, and the controller will enter the current charging limit.
2. Battery reverse connection protection
The system will not work after the battery is turned on inversely, and the controller will not be burned.
3. Photovoltaic input voltage overvoltage protection
The controller will automatically turn off the PV input if the voltage at the PV array input is too high.
4. PV input short circuit protection
The controller will disconnect the charging after the PV array input is short-circuited, and the charging will automatically resume when the short-circuit condition is cleared.
5. PV input reverse connection protection
When the polarity of the PV array is reversed, the controller will not be damaged and will continue to work normally after correcting the wiring error.
6.Load over power protection
When the load exceeds the rated power, the load will delay protecting the output.
7. Anti-reverse load protection at night
Prevent the battery from discharging through the battery plate at night.
8.Over temperature protection
TVS lightning protection
