Bosch BMA400 solves 4 major pain points in wearable devices

[Introduction] The fact that the wearable device market is still struggling to climb today shows that suppliers have not been able to completely solve the four major pain points of the wearable device consumer group: frequent charging, limited functionality, tedious ID design, and Large size or volume. Fortunately, Bosch can help today.

Today, the market for wearable devices represented by smart watches, children's watches, and smart bracelets can be said to be a new market growth highlight. According to the latest report from market research firm IDC, the global total wearable device market is expected to be 1 in 2017. Shipments of 13.2 million units increased to 222.3 million in 2021, with a compound annual growth rate of approximately 18.4%.

Mr. Leopold Beer, President of Bosch Sensortec Asia Pacific, said: “Today's wearable device market is clearly showing four major trends. First, the market is increasingly demanding embedded low-power solutions; The growth of the wearable device market is no longer limited to the health market, but from the most basic bracelet to the development of hybrid / smart watches; third, well-known fashion brands have begun to enter the wearable device market; fourth is the wearable market Equipment is starting to become more diverse, such as watches, earwear, clothing and jewelry."

Bailib said that the shipment of hybrid bracelet/smart watch products is expected to increase from 61.5 million in 2017 to 149.5 million in 2021.

In general, if the future wearable devices can make significant improvements in the following four major power experience pain points, I believe that the market growth rate will certainly be faster, after all, fashion brands, jewelry brands, high-end apparel brands to the user market The impact is great, and the profit margin is rich enough.

The pain points of these four major user experiences can be summarized as follows: 1) Because the user market requires the function of 'permanent communication', most of today's smart wearable devices need to be charged frequently; 2) many wearable devices have limited functions; 3) many can Wearable devices are boring in design and are reluctant to invest in ID design; 4) The size and weight of smart wearable devices continues to increase.

Bailib pointed out: "Today's user market requires smaller, low-power, multi-functional wearable devices, and it is best to be a stylish product."

To meet this demand in the market, Bosch's ultra-low-power accelerometer BMA400, which won the Technology Innovation Award at the 2018 CES show, can help. This product is specially developed for the wearable device and IOT market. 2x2x0.95mm, not only built-in counters, but only consumes 4uA, and it is also equipped with an intelligent power management system specially designed for battery-powered devices.

“The BMA400 ultra-low-power accelerometer is mainly used in wearable devices. Its step-by-step power consumption requires only 4μA in the step-by-step mode. The overall power consumption is reduced compared to most existing accelerometers. 90%, if the smart watch needs to be recharged once a day, then it only needs to be recharged once in 10 days, which greatly improves the consumer experience, no longer needs to charge the watch every day, and its application can be more diversified. ”

Bosch has four business divisions, the largest being the automotive and intelligent transportation sectors, as well as the industrial technology, energy construction and consumer electronics sectors. The four divisions are still dominated by automobiles, with sales of more than 7.8 billion euros in 2017. The European market is Bosch's main source of revenue, with Asia Pacific and the US contributing 30% and 18% respectively.

At present, there are about 400,000 Bosch employees in more than 60 different countries. Bosch has a lot of investment and layout in China. One of the most important is engineering R&D investment, which accounts for about 10% of investment. In general, Bosch is a company mainly for the automotive business, but there is also a consumer business, which is the Bosch Sensortec division. Consumer sensors are the main business of Bosch Sensortec.

MEMS (micro-electromechanical) sensors are the main development trend of consumer sensors. At present, the global MEMS sensor market is about 500 million US dollars. The main applications include mobile phones and consumer smart applications in addition to automobiles. Bosch has become the world's leading MEMS. One of the sensor suppliers.

Sensors are the foundation of the future of the Internet of Things, and Bai Libo said: "Bosch Sensortec is ready to open up the role of our product applications in this field and provide more suitable solutions to our design creators."

In 2007, a large number of smartphones were used, and the application of sensors has spread all over the mobile phones. From the initial acceleration sensors to gyroscopes, pressure sensors, and humidity temperature sensors, this is the main factor for Bosch's growth. .

Bailib pointed out: "In the future, we will introduce new sensor applications in the mobile phone field to enhance the value of mobile phones and sensors. But we see that the future direction is not only in mobile phones, but also in consumer electronics, AR, VR, and intelligence. Glasses, smart industrial technology, robots, bracelets, etc., there will be many different directions in the future. These directions require better sensor solutions or even system-level solutions. Bosch will invest more in these areas in the future. ."
