Wearable devices will be a major application area for the future of the Internet of Things, and are expected to grow to 145 million units by 2018. As the wearable device technology becomes more advanced, it will gradually be accepted and integrated into life. In the future, various applications of the Internet of Things will be expected to be connected in series through wearable devices and accelerate the formation to make the consumer's living environment more comfortable. wonderful.
The concept of the Internet of Things stems from the concept of the interconnection of things and things discussed by William Henry Bill Gates III in the 1995 Road to the Future. Through the detection of environmental data, and through mobile network transmission and data processing, the Internet of Things can instantly control various home devices and provide rapid care services, but limited by the network transmission technology at the time, the term Internet of Things. It represents only a blueprint for a huge intelligent system.
IoT applications have a wide range of sensors with good growth potential
With the development of the global network foundation, today's fourth-generation mobile communication (4G) and cloud computing environment provide high-speed data transmission processing capabilities, which makes the face of the Internet of Things blurred. The information collected by the sensor is used for information integration and data remittance in a wired or wireless manner, and then enters the software processing level for data analysis and application. The applicable level is gradually extended beyond the personal home environment, including wearable devices, electronic medical care, smart urban environmental monitoring systems, safety first aid strain systems, industrial control, audio-visual entertainment, video streaming, etc. Session.
According to US network equipment company Cisco, international research institute Morgan Stanley and International Data Information Corporation (InternaTIonal Data CorporaTIon, IDC) for global IoT device installation statistics, its equipment by 2020 The total output value of demand will reach 75 billion US dollars, and the compound annual growth rate will reach 8% or more. Figure 1 shows the IoT IoT application, including IP CAM, smart appliance/temperature control, electronic lock and smart remote control.

The IoT industry chain includes components manufacturing, equipment and system integration, network operations, terminal equipment and application services, and components such as RFID, communication chips, sensors, GPS, etc. At present, the global sensor market accounts for about 5% of the semiconductor market. With the rapid development of industries such as IoT, smart phones, automotive electronics, medical electronics, smart cities, etc., wireless (Wireless) and low sensor products are available. Technologies such as Low Power, Miniaturized, Standardization, Low Cost, Composite, Stability, and Reliability put forward higher requirements. The future growth potential of the sensor market is expected to be higher than the overall semiconductor market. .
Taiwan has a division in IC design, foundry and packaging and testing industries. It has the world's top design and process teams. With the strength of 3C products, it is expected to fully develop sensor components. Integrated from the upper/middle/downstream, it can cultivate Taiwan's representative IoT sensor supply chain.
Wearable device features multiple batteries designed into future challenges
Based on the huge IoT system, wearable devices will be a major application area for the future Internet of Things. The MIC (2014) has pointed out that the market for wearable devices in 2014 is estimated to be 3,490. Wantai, which accounts for 2.9% of smart phones, is expected to grow to 145 million units in 2018, accounting for 7.7% of smart phones.
In recent years, various domestic and foreign manufacturers such as Apple, Google, Sony (SONY), Samsung (SAMSUNG), ASUS, HTC, etc., have launched wearable devices including smart glasses, smart headphones, smart watches, wisdom bracelets. Wisdom rings, smart pants, smart shoes, etc., intend to preempt the layout of this huge consumer market. The main features of wearable devices currently include:
. Health management: The device has built-in sensors, including acceleration, heartbeat, temperature, gyroscope, etc., monitors the wearer's status data, and analyzes the sensory data to know the wearer's immediate status, such as running, walking, jumping, standing. Sleeping and breathing heartbeat status, etc., with wireless transmission modules such as Bluetooth or Wi-Fi, can be instantly connected with smart phones, allowing the wearer to long-term statistics and record health status.
. Remote control: Connect to the device through wireless transmission, such as a user's computer, home appliance or smart phone. The user can remotely control the home appliance from a distance by issuing a command through the wearable device.
. Entertainment: Allows users to play music and movies, even gaming applications, directly on wearable devices without having to carry heavy equipment.
. Data transmission: not only the sending and receiving of emails, browsing the Internet, but also the wearable device can provide video streaming services such as instant playback and recording. For example, Google glasses, users can use voice input commands to start the micro-lens equipped for instant recording. Image and upload it to the cloud database.
. Instant positioning: With the Global Positioning System (GPS), you can return to the wearer's position at any time, for elderly and child care and health monitoring, and even with the medical system. When the wearable device detects a sudden illness or condition, such as heart disease, epilepsy, stroke or car accident, it can directly link to the medical network and notify the family, and immediately dispatch an ambulance to the patient's location to grasp the golden rescue opportunity.
Taking Apple's products as an example, mobile phones, tablets, TVs, watches and computer devices have been communicated through cloud management. The incoming call of the mobile phone can be answered freely on the computer or watch. The half of the file processed by the computer can be synchronized to the mobile device, and the lost item can be retrieved by another device.
However, the goal of the Internet of Things is not only applied to typical electronic products, but its real expectation is to digitize all the objects in the real world. In the future, the materials around us will be embedded in electronic tags, combined with wireless networks and various sensors, through the central server to manage, remotely control, search and obtain statistical information.
At present, the main bottleneck of the wearable device is the battery power and the weight and volume of the product. The weight and volume of the wearable device directly affect the wearer's experience. If the device is too heavy, it will not only cause the user to feel Discomfort, the time and willingness to continue to use will drop dramatically. However, while reducing the volume and weight, it also limits the capacity of the battery, and as the data transmission demand and the number of sensors installed increase, the required power consumption is gradually increased, thus reducing the power consumption. And battery management technology will be a major focus of the wearable device hardware industry.
Wearing a device to play the corner of the object is easier to live
Although the wearable device currently provides users with various new experiences and functional applications, most wearable devices only provide functions expansion of computers or smart phones, and are not independent mainstream products. The research and development of technology is still in its infancy, but as the wearable device operation technology becomes more advanced in the future, it will gradually be accepted and integrated into life. The control method will also develop from touch panel, speech recognition, smart gestures to virtual reality projection. Eye tracking and brainwave control make the bulky remote control disappear into life.
In addition, as the ageing problem in Taiwan becomes more and more obvious, the care of the elderly and young children will be an important part of the government's need to improve planning, and wearable devices can provide the most important health monitoring and immediate positioning applications for this demand; Blood pressure, blood sugar, body temperature, body posture and positioning coordinates can prevent the loss of young children and mentally handicapped people and monitor physical health information, which not only can alleviate the shortage of care, but also provide a huge source of business opportunities for wearable devices. .
Imagine that all the appliances in the house need only a gesture, a look, or even a thought, and can be actuated according to their own needs, and even actively calculate the most suitable environment parameters for the user and adjust to the most comfortable state. Through wearable devices, future users and home appliances will gradually be connected in series by the Internet of Things, and the home environment will be more comfortable and exciting.
