A recent WeChat article titled "Don't be taken by CES, the smartphone dominates the world has just begun" is quite hot. The author believes that the next five years will be the key period for activating the smartphone economy, and last year's Mobile World Congress was released. The Mobile Economy 2015 report predicts that global smartphone penetration will increase from 37% in 2014 to 65% in 2020. In contrast, in China, the wave of new machine launches did not mean that there was no enthusiasm.
Having said that, today's mobile phone innovations are lacking, so is there any application scenario and implementation technology that will activate smartphone innovation in the next few years? At the recent EEVIA 5th ICT Media Forum and 2016 Industry and Technology Outlook Seminar Beijing, Allen Tsai, Senior Business Manager of Maxim Mobile Division, summarized the following wave of mobile phone evolution directions worth looking forward to:
1. From large batteries to energy harvesting/multiplexing;
2. From the straight screen to the curved display;
3. From basic sensors to sensor networks;
4. From the center of the phone application to the perception of biological/environmental awareness.
Allen said: "At present, when major mobile phone manufacturers release new machines, they mainly emphasize how the functions or hardware configurations of mobile phones themselves. In my opinion, it is more important to see the significant impact of mobile phones on human life and culture. What will the next generation of mobile phones change? Maxim believes that in addition to the evolution of various hardware technologies and application apps, mobile phones will have a major impact on the monitoring and health management of individuals in the near future. The social entertainment-centric platform transitions to a platform centered on biology and environmental perception, which is one of the innovative directions for mobile phones in the future."
In particular, he stated that people's attention to the environment and health is increasing, and the application of environment and biosensors in mobile phones is promoted. The data collected by sensors is aggregated and analyzed to form a new service business model, and promote mobile phones. The development of perceptual computing systems, as part of a ubiquitous computing environment, senses the physical environment and adapts its behavior.
For biosensors, in addition to regular signage monitoring, Allen highlights the future of electrocardiogram (ECG) in mobile phone security certification applications. Using ECG for safety certification has the following advantages over fingerprints and irises:
1. The repetition rate is as low as one in four million, and the repetition rate of the fingerprint is one in 100,000;
2. High safety factor: The electrocardiogram is always changing, it is not easy to be acquired by others, and only the ECG signal of the living body is meaningful, so there is no need to worry about being hurt.
However, the use of ECG for safety certification also has its shortcomings. For example, the phone screen is now unlocked and unlocked in less than a second. If you use ECG to unlock, you need to put your hand on the phone for about 6 seconds to 8 seconds, which is too long for the boot application, so it is not suitable for unlocking the phone. However, for applications that require a high level of security protection and authentication (such as large amounts of online remittances and financial transactions), it is appropriate to use ECG for security certification. In addition, it is well known that electrocardiogram is also an important indicator of personal health management. With pulse wave (PPG) measurement, the blood oxygen content of the user's body can be detected to assess the health status.
Allen then detailed the use of Maxim's health (biological) and environmental sensor solutions to achieve product differentiation, including non-contact NFC thermometers; formaldehyde, sulfur dioxide, carbon monoxide and other toxic gas detection; UV index monitoring: online color ratio of goods Wait a minute. The design requirements of the above application scenarios have common features: ultra-low power consumption, high accuracy, minimum footprint, and complete solution (ie, industrial design for mobile phones and wearable devices).
Although many companies are providing biological and environmental sensors, Maxim's philosophy is to make simple and easy-to-use solutions that provide innovative technologies and complete holistic solutions that benefit next-generation mobile phones and smart mobile devices, including: advanced sensor technology and complexity. Photovoltaic systems, application-oriented advanced algorithms, integrated software, applications that surround the everyday life and support the connection to the cloud (App).
