Ocean analysis of the future development of multi-dimensional force sensors
Future multi-dimensional force sensor products will become more complicated. As sensors are gradually favored, adding sensors to the hardware of many smart products is a big challenge for the development of end products. Taking wireless interference as an example, the current mobile phone itself is very complicated to deal with wireless signals. It is necessary to solve 3G and solve Wi-Fi. Therefore, when adding a sensor that supports wireless communication capabilities such as NFC, it is necessary to fully consider the interference problem. .
The traditional approach is that the core chip exists only as a channel and is passed to the upper application after receiving the signal, so the channel is very simple, but this will increase the complexity of the terminal design, because the latter needs to solve how to use the interface, the interface is not enough. What to do, and how to deal with the upper software.
Currently, some chip vendors are trying to change this process to reduce the complexity of development.
Wang Yufei, senior product manager of Qualcomm, said that Qualcomm's approach is to solve the above problems through a dedicated processing unit with independent computing capabilities on the chip. From the current usage situation, "I think these applications have matured."
However, for the final terminal manufacturer, it has already considered what kind of sensor should be loaded when designing the product concept, although it will increase the workload, but because many can be developed in parallel, it will not extend the product development cycle. .
The variety is still increasing Although the multi-dimensional force sensor itself is very rich in variety, it is still an emerging industry as a whole.
On the one hand, from the use of sensors on the terminal, more is to use the microphone's hearing and camera vision and some simple sensors. For the future, most respondents said that pressure sensors and optical image sensors will be used more widely, such as indoor navigation, shooting anti-shake.
On the other hand, the development of a variety of sensor integration is gradually favored. However, some insiders believe that although integration will bring convenience to development, it will sacrifice flexibility. However, it is undeniable that the development of mobile terminals is bundled with sensors, and sensors such as 3-axis accelerometers, 3-axis gyroscopes, microphones, and stereo wave filters have become standard equipment.
Wang Yufei said: "The types of sensors may increase, but what is more critical is the application form between sensors, especially in software, which will become more intelligent."
According to some public information, in 2013, the accelerometer will continue to rise, the gyroscope incident rate will increase from 10% to 30%, and the geomagnetic meter incident rate will rise to 70%; the humidity sensor will appear in the mobile phone reference design for the first time. .
However, Liu Gang, director of product planning at Hisense Communications, said that although such sensors can be put into production from the technical point of view, it is not suitable for application on mobile phones. "This is still a matter of time."
This also shows that in addition to the existing hardware functions, the mobile terminal can also add new functions by adding different kinds of sensors, thereby achieving more user requirements.
Applications need to find a balance. Although there are reasons to believe that with the increase in the variety of multi-dimensional force sensors, the techniques of temperature, body, brainwave control, fingerprint recognition, and face recognition no longer need to be found in science fiction movies, but only when these technologies are mature enough. And cheap, and popularized on mobile terminals, can reflect its commercial value, which in turn affects the design of next-generation terminals.
