Wearable devices become the IoT control center to break through in these three directions
At present, wearable devices have become the core carrier of the Internet of Things, and it is expected to become the IoT control center in the near future. However, the development of the wearable device industry still faces a series of problems such as sensor technology, big data technology, endurance, data security and privacy protection. It should achieve breakthroughs in the following three aspects:
The promotion of key technologies is the core
In the future, the development direction of sensor technology must be miniaturization, intelligence and networking. The sensor size is reduced, the accuracy is improved, power consumption is reduced, and integration is improved. The operating system will achieve high reliability and scalability. Techniques such as voice interaction, somatosensory interaction, and eyeball recognition will be widely applied to wearable devices to achieve multi-dimensional signal cooperative control. In terms of battery technology, human kinetic energy generation and renewable energy utilization will greatly enhance the user experience of wearable devices.
Provide protection against data security threats
On the one hand, there is a need to protect data security and privacy from a technical perspective. According to the data flow, data security and privacy protection technologies for wearable devices are improved from five aspects: data communication, storage security, access control, hardware and software integration, and data security detection. On the other hand, according to the development of the wearable device industry and the needs of the market, the establishment of standards should be accelerated to establish a baseline for the wearable device industry.
Make full use of "black technology" to improve product performance and user experience
For example, the use of flexible electronic materials in wearable devices not only enables the products to have good electronic performance, but also has good ductility and flexibility, improving the user experience and enhancing user stickiness. Graphene, a new material based on carbon, may also play a key role in the breakthrough of wearable technology in the future.

USB3.0 is a USB specification, which was initiated by Intel and other companies. The maximum transmission bandwidth of USB3.0 is as high as 5.0gbps (500MB / s).
While maintaining compatibility with USB2.0, USB3.0 also provides enhancements: significantly increased bandwidth (up to 5Gbps full duplex); better power management;
more power; faster device identification; and higher data processing efficiency.
The reason why USB 3.0 has the performance of "speeding" is entirely due to the improvement of technology.
Compared with USB 2.0 interface, USB 3.0 adds more physical buses in parallel mode.
You can pick up a USB Cable and look at the interface.
On the basis of the original 4-wire structure (power supply, ground wire, 2 pieces of data), USB 3.0 adds 4 lines for receiving and transmitting signals.
So there are eight lines in the cable and on the interface.
It is the additional 4 (2 pairs) of lines that provide the bandwidth required for "superspeed USB" to achieve "over speed".
Obviously, two (1 pair) lines on USB 2.0 are not enough.
In addition, in the signal transmission method, the host control mode is still used, but the asynchronous transmission is changed.
USB 3.0 makes use of two-way data transmission mode instead of half duplex mode in USB 2.0 era. In short, data only needs to flow in one direction, which simplifies the time consumption caused by waiting.
In fact, USB 3.0 does not take any rarely heard of advanced technology, but theoretically increases the bandwidth by 10 times. As a result, it is more friendly and friendly. Once superspeed USB products come out, more people can easily accept and make better customized products.
