Smart wearable device need huge passive components and higher requirements

2024-05-05

According to statistics from research organization Canalys, in the third quarter of 2023, global shipments of smart wearable wristband devices (smart bracelets, smart watches) reached 51 million units, a year-on-year increase of 4%. Led by the Indian market, Q3 global basic smartwatch shipments increased by 20% year-on-year, making it the only subcategory to achieve year-on-year growth. In terms of manufacturer rankings, Apple still ranks first with a 17% share, but its shipments fell by 12% year-on-year; Xiaomi ranked second with a 12% share, and its shipments increased by 39% year-on-year, among which Xiaomi Mi Band 8 ranked second. Sales in overseas markets drove shipment performance.

The recovery of Huawei's mobile phone business has further strengthened its ecosystem, driving Huawei's wearable device shipments to increase by 45% year-on-year, and ranking third with a market share of 10%. Thanks to the new iteration of Galaxy Watch 6, Samsung returned to fourth place with a share of 8%. The fifth is the Indian brand Fire Boltt, which has grown rapidly in the Indian market, with shipments increasing by 53% year-on-year. Looking at different markets, Xiaomi's smart wearable wristband devices rank first in Africa and Latin America, with a market share of 20%. Apple ranks first in the Middle East, Western Europe, and North America.

In the Chinese market, in Q3 2023, Huawei ranked first with a share of 34%, an increase of 57%; followed by Xiaomi, with a market share of 24%; XTC (Little Genius) ranked third with a share of 10%. Apple and OPPO rank fourth and fifth respectively in the Chinese market.

From bracelets, smart watches to TWS headsets, there are always hot models in the wearable device market, and the market popularity continues to rise. At present, the annual shipment volume of wearable devices has surpassed that of personal computers, becoming one of the application directions that component manufacturers must pay attention to. Among them, medical health has become the main function of wearable products, according to statistics from market research organization Yole. , global shipments of wearable medical and health products reached 347 million pieces in 2019. The agency predicts that by 2025, shipments of wearable medical and health products are expected to exceed 750 million pieces, doubling from 2019.

Entering 2022, the miniaturization and multi-functional integration of sensors and chips will further increase the portability of wearable devices or improve the battery life of wearable devices; the interaction between smart wearable devices and smart home appliances and other devices other than mobile phones functionality will be further enhanced; control methods will be more diversified, and gesture control functions will be adopted by smart wearable devices; independent communication functions will gradually become standard features of smart watches. In short, wearable devices will develop in the direction of richer functions, more diverse forms, more accurate indicators, and longer battery life, and will play a greater role in many fields such as social networks, medical health, navigation, business, and new media.

The characteristic of smart wearable devices is that the more data they can detect, the more value they can bring to users. Therefore, even if normal life order returns to the future, wearable medical devices will play an increasingly important role.

The portable nature of wearable devices facilitates long-term monitoring of the physical condition of patients who do not need to be bedridden, which is very helpful in the management of chronic diseases with certain fatal risks, such as chronic obstructive pulmonary disease, atrial fibrillation, and obstructive sleep apnea.

To meet medical-grade applications, new requirements have been put forward for key components in wearable devices: they must not only adapt to the "thin, light and short" size requirements of traditional wearable devices, but also meet the high-precision and high-reliability index requirements of medical-grade applications. , but also consider low power consumption, battery life, and long working hours.

Medical-grade applications must first have medical-grade accuracy. Taking body temperature detection as an example, clinical-grade accuracy must reach an accuracy of ±0.1°C within the body temperature range. ADI's MAX30208 digital temperature sensor can meet the clinical temperature detection requirements. The chip has an accuracy of ±0.1°C in the range of +30°C to +50°C, and an accuracy of ±0.15°C in the range of 0°C to +70°C. Since components themselves generate heat when working, eliminating thermal interference from components is a factor that needs to be considered in clinical-grade temperature measurement equipment. The operating current of MAX30208 itself is very low, only 67μA, and the current consumed in standby is 0.5μA. The low operating current ensures that the heat dissipated by the chip itself is low. In addition, the chip heat is dissipated from the bottom pins of the package, so the chip places the temperature sensor on the top of the package, away from the chip pins, thus greatly reducing the thermal interference of the components.

Thin, light and short -Smart wearable devices incorporate a variety of passive components to function effectively. These components are essential for various functions, such as power management, signal processing, connectivity, and user interface. Here are some of the key passive components commonly found in smart wearable wristband devices:

1.Resistors:

Used for controlling current and voltage levels in different parts of the device, including LEDs, sensors, and power management circuits.

2.Capacitors:

Provide energy storage, filtering, and smoothing in power circuits. They are also used for decoupling and tuning in various electronic components.

3.Inductors:

Used in power supply circuits for energy storage and filtering. They can also be found in radio frequency (RF) circuits for tuning and filtering.

And others likes Crystals and Oscillators,Resonators,Diodes,Transistors,Sensor Components, LEDs (Light-Emitting Diodes), Touch Sensors,Connectors and Interconnects,RF Filters,Passive RFID Components,Battery,PCB (Printed Circuit Board)

These are general categories, and the specific components and their quantities depend on the design and functionality of the wearable device. Design considerations may also include factors like power efficiency, size constraints, and overall performance. Manufacturers may use a combination of these passive components to achieve the desired features and functionalities in smart wearable wristband devices.
