Overcome wearable design pain points, ultra-low power consumption and high performance combined with sensors are just needed

2017 saw the emergence of many exciting products in the wearable market such as new smartwatches, tech-enabled apparel, and fitness activity trackers. According to a survey report on global wearable devices released by IDC, shipments of wearable devices reached 115.4 million units in 2017, an increase of 10.3% from 104.6 million units in 2016. Shipments in the overall wearables market will increase from 113.2 million units this year to about 222.3 million units in 2021.

The sub-fields of IoT such as smart home, smart agriculture, and environmental monitoring have achieved results, but they have not been widely popularized. Ralf Schellin, general manager of Bosch Sensortec’s microelectromechanical systems (MEMS) product area, said at the press conference: “Because IoT applications are too fragmented, I don’t think there will be a killer application outbreak, but smart home and personal health related applications. The value will be reflected in the relatively early stage, especially the combination of these two fields, obtaining personal health through wearable products, and then integrating with the smart home, its value will be easily presented.”

As the size and weight of smartphones continue to increase, it is very inconvenient for users to carry them when exercising, and smaller-sized wearable devices that integrate motion detection performance are applied. Wearables require frequent charging due to the “always on” feature, which requires a low-power solution for longer battery life. At the same time, in order to better meet the needs of consumers, the functions of the bracelet are constantly enriched. In addition to the step counting function, fashion and design elements are also added. In addition, wearable devices will also derive more diversified products, including watches, earrings, jewelry, clothing, etc.

Usually the low power consumption and high performance of the accelerometer cannot be achieved simultaneously, and the BMA400 has been designed in the product at the same time. Ralf Schellin emphasizes: “The BMA400, with its ultra-low power consumption of only 4 μA from its step counter, combined with its intelligent power management, can greatly extend the life of wearable device batteries.”

BMA400 is an unparalleled product specially designed for wearable devices. In addition to the characteristics of low power consumption and high performance, its volume is only 2.0 x 2.0 x 0.95mm³, which can be designed into very tiny watches, earrings and even Among the glasses, thanks to its compact package, the BMA400 can be integrated into other wearable devices to promote the promotion of wearable devices with fashion elements.

In addition to being used in wearable devices, the unique combination of ultra-low power consumption and high performance of the BMA400 can inspire developers to design more IoT-related applications, and even IoT application scenarios such as aquaculture and bridge vibration detection where batteries cannot be replaced frequently .

Breaking through the technical bottleneck, the AR/VR high-end market has broad prospects

According to Digitimes Research, from 2017 to 2022, the compound annual growth rate of global shipments of AR and VR headsets will reach 41.6%, and the sales of higher-end AR/VR devices is a question of whether this market can be further expanded. key.

Ralf Schellin pointed out: “Low-priced head-mounted displays will gain more market share in the next two years, but we can see more independent high-performance helmets will gain market share in the long term, AR and VR applications. will grow rapidly.”

The next generation of the BMI055, the BMI085 is a high-performance inertial measurement unit designed for virtual and augmented reality applications. For AR/VR devices most prone to dizziness, the BMI085 combines an extremely low-drift gyroscope with a low-noise accelerometer to significantly reduce the uncomfortable motion sickness effect, and its ultra-precise instantaneous detection of head motion will The time delay is reduced to an almost imperceptible minimum. Additionally, the BMI085 is rock-solid temperature stable, capable of delivering impressively low temperature coefficient compensation (TCO), typically less than 0.2 mg/K, and temperature coefficient sensitivity (TCS) up to 0.002%/K. The bias instability of the gyroscope is usually less than 2°/h.

The combination of IoT and AI, the interactive projection module pushes IoT applications to a higher level

According to IDC research data, global Internet of Things (IoT) spending is expected to grow at an annual growth rate of 14.6% to $772.5 billion in 2018, surpassing the $1 trillion integer barrier in 2020, and further rising to $1.1 trillion in 2021 , the 2017-2021 average compound annual growth rate (CAGR) is expected to be 14.4%. In the future, more application scenarios such as smart speakers and voice control will require more and more low-power and compact solutions and visual user interfaces. Despite this, the development of IoT is still limited by many aspects: large-screen displays, mobile devices need to be charged frequently, and online shopping voice control is not enough for all scenarios.

“The interactive projection module is small in size, which solves the pain point of the large Display screen. It also has ultra-low power consumption performance, the interface moves during projection, and does not need to move when it is not projected. The interactive projection module can realize focus-free laser through MOEMS technology. projection and the flexibility to transform any surface into a particularly intuitive and visually appealing virtual user interface (UI), ideal for use with home appliances, smart speakers, augmented reality glasses, wearables and more.” Bosch Sensortec GmbH Leopold Beer, president of the Asia-Pacific region, said, “Compared to DLP and LCOS technology, MOEMS laser scanning technology uses lasers to directly hit the place to be imaged, so it does not need the focusing ring of the lens to focus, and automatic focusing can be achieved.”

The emergence of the Bosch Sensortec interactive projection module is expected to promote the application of various segments of the Internet of Things to a higher level. Leopold Beer is very optimistic about the development of interactive projection applications. “In the future, there will be more and more usage scenarios, and more users will accept its value. Three years later, there may be a large outbreak period.”
