In China, Bosch has 62 companies. From 2011 to 2016, the total investment in China was nearly 22.9 billion yuan, and the number of Chinese employees reached nearly 59,000. In order to strengthen local innovation capabilities, 36 production bases have been established, including 21 automobile-related production bases, and 22 technology research and development centers, including 12 automotive-related technology research and development centers, with more than 6,300 R&D personnel in China. .
With such strength and innovation, Bosch, when the MEMS price war in the consumer electronics market represented by mobile phones is in full swing, Bosch also has enough reasons for “transformation and upgradingâ€, which will look more like wearable, AR/VR, Internet of Things and so on. Market for growth space to develop new, more challenging and challenging MEMS products, upgrade to integrated solutions such as embedded software and algorithms, integrated sensing combinations, custom IoT sensors and actuator solutions for users Pain points, leading the world of perception in the future.
At the 2018 Munich Shanghai Electronics Show, Bosch Sensortec demonstrated three new core product portfolios, the ultra-low-power accelerometer BMA400 for wearables and the Internet of Things, a high-performance inertial measurement unit for enhanced and virtual reality ( IMU) BMI085, and an interactive projection module for virtual user interfaces in the Internet of Things.
These will help creative engineers and designers meet these challenges and transform and innovate, thus laying the foundation for a truly smarter world.
Three new core product portfolios from Bosch Sensortec
Direct hit point 1: Wearable devices must make a trade-off between ultra-low power consumption and high performance.
Today's smartphones are getting bigger and bigger in size and weight, and it is very troublesome to carry them in your pockets or arms while you are exercising. This logically drives the demand for wearable devices such as smart watches and motion trackers, and provides a convenient and permanent solution for health, sports and fitness monitoring, and thus plays an increasingly important role in our daily lives. IDC (International Data Corporation) predicts that the overall wearable market is expected to grow from a total annual growth rate of 18.2% in 2017 to 222.3 million in 2021 from a total of 11.2 million in 2017.
Regardless of where wearables are applied, there is a common user experience problem: consumers continue to demand longer battery life, are more portable, have more versatility, and have accurate data collection. Reducing power consumption has created a huge competitive advantage for innovative manufacturers who want to succeed in today's competitive environment and expand their market share. At the heart of many exciting new wearable applications, such as smart rings or necklaces, will be introduced in the near future, with ultra-low power consumption and extremely efficient power usage.
Of course, the demand for wearable devices in the future will far exceed health and fitness, and will be characterized by multiple functions, visual design appeal and moments of the line, replacing many of today's “bulky bricks on the wrist†while incorporating smart rings and fashion. In the field of handbags or wallets. This shift will require batteries with higher energy densities, but in the end, smart power will determine the success or failure of most projects.
So how can product manufacturers really reduce power consumption to build such new devices? Motion sensors are an integral part of wearable applications. To overcome these long-standing obstacles, Bosch Sensortec designed the BMA400, a small but powerful MEMS accelerometer designed to meet power challenges. According to Ralf Schellin, the BMA400 combines ultra-low power consumption and outstanding performance in a compact package with built-in counters and consumes only 4μA, only 2.0 x 2.0 x 0.95mm3. The power consumption is reduced by ten times compared to the current accelerometer, and the performance is not compromised. To further extend battery life, the BMA400 automatically wakes up only when motion is detected and automatically returns to sleep mode after the motion has stopped.
Often, accelerometer designs must make trade-offs between low energy consumption and high performance. The BMA400 delivers the best of both worlds: its combination of low power, high performance and advanced features is unmatched by any other device on the market today – arguably out of reach.
Through continuous measurement, the sensor's high-quality measurement signal has been able to precisely define its cut-off frequency, which makes it extremely vibration-resistant. The BMA400 can distinguish between real alarms such as glass breakage and false alarms caused by random vibrations, which makes it possible to use it in IoT use cases such as home smart security systems. Therefore, this sensor can effectively prevent false alarms triggered by external environmental vibrations such as construction engineering.
The advanced features of the accelerometer will also make the motion detection and permanent step count function of the multi-function wearable device consume no power from the application processor. Thanks to its compact package, integrated plug-and-play step counter, and activity recognition, the BMA400 is easy to integrate into new wearable devices, helping to advance new, exciting and stylish devices.
Direct hit point 2: AR/VR users are not happy with low latency and less vertigo experience
Augmented Reality (AR) and Virtual Reality (VR) are a market that has continued to evolve over the years. Although the necessary technology has been steadily advanced, the lack of user experience has hampered its promotion. For example, more serious delays, instability and noise can cause motion sickness, which can lead to nausea and other symptoms that make users feel uncomfortable. In addition, issues such as overheating of headsets, wireless data transmission speed and reliability, and generally higher prices present additional challenges for full market penetration.
The augmented reality and virtual reality markets have so far lacked really appealing applications. However, with the launch of the new flagship augmented reality/virtual reality products, the prospects for mobile devices in these areas are beginning to evolve. The range of possible applications of this technology is virtually endless, for example in education and industry. Augmented reality glasses will be very popular in these areas. Overall, IDC predicts that by 2021, the total market for augmented reality and virtual reality headsets will increase to 81 million units, equivalent to a compound annual growth rate of 56%.
In order to achieve the necessary key quality and broad consumer acceptance, vendors need to find a way to mitigate the unpleasant user experience issues that hinder the development of today's augmented reality/virtual reality products. Bosch Sensortec's new BMI085 combines a very low drift gyroscope with a low noise accelerometer to significantly reduce unpleasant motion sickness effects. Its ultra-precise transient detection of head motion shortens the time delay to an almost imperceptible minimum.
The VR glasses with the new BMI085 are still very lightweight.
Ralf Schellin further stated that the extremely low latency of the new BMI085 enables headset manufacturers to eliminate image drift and provide a realistic real-world experience. The IMU offers low motion to photon delays of less than 3 ms and is capable of near perfect stability in high temperature fluctuations often encountered in continuous head mounted displays (HMD) or augmented reality headset scenarios. This system further enhances accuracy and is critical for today's lightning-fast HD augmented reality/virtual reality applications.
The sensor's accelerometer has rock-solid temperature stability and offers impressive low temperature coefficient compensation (TCO), typically less than 0.2 mg/K and a temperature coefficient sensitivity (TCS) of 0.002 %/K. The gyroscope's bias instability is typically less than 2°/h.
The BMI085's gyroscope features a powerful closed loop analog-to-digital conversion mechanism that ensures low drift characteristics even in high temperature environments. The accelerometer achieves a noise density of less than 120μg/√Hz, and the accuracy of the IMU is further enhanced by the data synchronization of the accelerometer and the gyroscope.
Direct hit point three: virtual and flexible man-machine interface for the Internet of Things
Currently, the Internet of Things is driving growth in many industries. IDC predicts that global Internet of Things spending in 2018 will exceed $772 billion and will exceed the $1 trillion mark by 2020. To achieve such bold growth forecasts, IoT solutions will need to prove their value and overcome many technical challenges in terms of size, cost, power and availability.
The user interface has a lot of room for improvement and the potential to be developed to push the Internet of Things to a higher level. To smooth and expand the interaction between users and technology, Bosch has developed exclusive MOEMS laser scanning technology for projecting and sensing interactive images such as menus. In order to promote revenue, the user must be able to see the actual product image, as only the stimulus provided by the audio control interface is not sufficient to trigger a customer's purchase behavior, such as when shopping online.
The interactive projection module enables focus-free laser projection and the flexibility to transform any surface into a particularly intuitive and visually appealing virtual user interface (UI), ideal for Home Appliances, smart speakers, augmented reality glasses, wearables Equipment and other use.

The interactive projection module projects the virtual user interface image onto the surface and continuously scans to detect user gestures and interactions, such as touching, dragging, or clicking. The virtual interface that can be projected onto any surface on demand provides near-infinite application possibilities, without the need for physical control dialing and button blocking, and will revolutionize the IoT and consumer product space. Ordinary devices will immediately have an infinitely flexible IoT interface, and thanks to its compact and energy-efficient features, the interactive projection module is ideal for sci-fi functions such as projecting user interface images from smart watches and personal mobile devices.
The interactive projection module has the technical features needed to achieve this vision, including focus-free projection, compact size and low power consumption. This module enables product designers to create stunning user interface concepts that are expected to bring incredible levels of availability for IoT, smart homes and other applications.
No matter how many exciting new applications are developed for the interactive world, the challenges faced by engineers remain more or less the same, reducing costs and power while ensuring high performance. Balancing and meeting these requirements is where designers can prove their talents and create stunning New Products.
There is no doubt that sensors play a huge role in this increasingly intelligent, fast and connected world. These and other recent innovations from Bosch Sensortec in the areas of MEMS and MOEMS technology will play an important role in this fundamental change and ultimately achieve the goal of creating a smarter world.
