In recent years, smart wearable devices have seen significant development, with smart bracelets and watches leading the way. However, most of the functions offered remain limited to basic tracking—such as steps, sleep patterns, and heart rate monitoring. As a result, smart bracelets have lost their initial popularity. In contrast, smartwatches, particularly those from companies like Apple, have emerged as the more promising category in the wearable market.
According to a report by IDC, the global wearable market remains sluggish. In Q3 2017, total shipments reached 26.3 million units, showing only a modest 7.3% growth. Meanwhile, Gartner found that nearly 29% of smartwatches and 30% of fitness trackers were abandoned by users after purchase. This highlights the challenge of sustaining user engagement with wearable tech.
In July this year, Jawbone—a once-highly valued smart bracelet company with a $3.2 billion valuation—filed for bankruptcy, marking a major shift in the industry. Similarly, Fitbit and GoPro saw sharp declines in their stock prices around the same time, with Fitbit’s share price dropping by approximately 60% over the past year. Smart bracelets are gradually being phased out by many manufacturers, signaling a decline in their relevance.
Despite this, smartwatches are experiencing much stronger growth, with a 61% increase in the third quarter of this year. Apple Watch sales reached 3.9 million units, up by 500,000 from the previous quarter, and accounted for 23% of the overall wearable device market. This indicates that smartwatches are becoming the dominant product in the wearable space.
There are several reasons behind the rise of smartwatches:
1. They offer a distinct use case compared to smartphones, catering to different daily needs.
2. They can function independently without relying on a smartphone.
3. With AI voice interaction, they reduce the need for constant screen interaction.
4. They provide greater convenience and efficiency in areas where smartphones are less practical.
While the wearable market hasn’t grown as quickly as some had hoped, manufacturers are learning from the success of smartwatches. By adopting better design and functionality, they may be able to regain momentum and adapt to evolving consumer demands.
Thermal Overload Relay
Thermal Overload Relays are protective devices used for overload protection of electric motors or other electrical equipment and electrical circuits,It consists of heating elements, bimetals,contacts and a set of transmission and adjustment mechanisms.
Our Thermal Overload Relays had been divided into five series(as follow),with good quality and most competitive price,had exported into global market for many years:
LR1-D New Thermal Relay
LR2-D Thermal Relay
LR-D New Thermal Relay
LR9-F Thermal Relay
Intermediate Relay
The working principle of the thermal relay is that the current flowing into the heating element generates heat, and the bimetal having different expansion coefficients is deformed. When the deformation reaches a certain distance, the link is pushed to break the control circuit, thereby making the contactor Loss of power, the main circuit is disconnected, to achieve overload protection of the motor.
As an overload protection component of the motor, the thermal relay has been widely used in production due to its small size, simple structure and low cost.
