The development of semiconductor technology has made it possible to create new portable and wearable biosensing and monitor components that help people improve their medical skills, help them develop and advance their fitness activities.
Around the world, the population is getting older, and the demand for medical resources is growing. According to the United Nations population projections, by 2025, more than one-fifth of the world's population (nearly 2 billion people) will be over 60 years old. Many of them live in developing countries, where a rising standard of living has made the demand for public health services higher and lower for people under the age of 60. In the United States, recent policy changes have flooded millions of people into increasingly crowded public health systems, and from a global perspective, the Internet is helping consumers have more choices when they need medical care. room. These are just a few of the development directions, highlighting the importance of providing more effective medical services to more people now and in the years to come.
To some extent, addressing the shortage of resources requires more doctors, nurses, hospitals, drug supplies, and other basic ingredients related to treatment. However, even in a traditional hospital environment, there is a need to increase the availability of resources and equipment to meet the needs. In addition, although it is possible to provide the necessary medical personnel and facilities, each individual in the population is also required to pay more attention to personal health. People must care about their health and thus limit their need for certain professional medical services by maintaining good health and good physical condition. Society as a whole, in North America and around the world, as we seek new solutions to the enormous medical challenges we face, we must learn to lead a healthier lifestyle. An important factor in our clinical and residential settings that can help us meet these challenges is electronic technology, which includes advances in bio-stimulus sensing and health surveillance, such as those available at home and outing.

Changes in IC technology
Without the development of integrated circuit (IC) technology, people will not be able to appreciate the impact of increasingly popular biosensing and electronic health surveillance. In general, higher-end end applications are driving IC performance to levels that were previously unattainable. But performance is just one of three innovations in the semiconductor industry (the English expression of these three innovations starts with the letter P), and the other two are power dissipation and price. The progress made in these three areas has created new market opportunities. High-end performance technology is rapidly maturing and optimized for higher integration, smaller size, and better power. These advances can help this technology quickly move from high-end systems to a wider range of applications and applications. At the same time, this cycle is recurring, and this cycle will continue as new technologies for high-performance systems are re-developed.
Today, this migration takes place in many areas of health technology. For example, in Figure 1, the practical electrocardiogram (ECG) developed around 1903 is very large and immovable, and the patient needs to immerse the limbs in a container containing the saline solution to record the ECG. Although the basic principles have not changed, this electronic instrument has evolved from a cumbersome laboratory device to a compact electronic system that is used in any hospital. And he is still evolving into a wide range of biosensing and bio-stimulus applications outside of the traditional hospital environment, including sports watches and even gaming systems. In these applications, heart rate is used to monitor the player's real-time emotional state as the game's difficulty changes.
A new way to track our health
As this technology continues to evolve, electronic systems based on analog and embedded processing technologies enable people to incorporate biosensing and health monitoring into their daily lives in new ways. As shown in Figure 2, today's electronic devices are not ugly to wear, and can even be said to be fashionable. They can be worn on wrists, legs, chest or other parts of the body, or combined with portable electronic accessories that sense personal data. Together. These devices often communicate wirelessly with smartphone applications that process, store, and display information, or other central programs. These types of personal and wearable sensing electronic components are a major trend in the consumer and home health industries. It’s never been as easy to follow your body data and be responsible for your health through wearable electronics.

Much of this data includes readings that look more traditional, pulse pulsating oxygen levels, blood sugar levels, and other vital signs that help people understand their health. However, even in these traditional biosensing applications, wearable wireless electronics can be used in new ways. For example, in the early years, a diagnosis of arrhythmia or a specific arrhythmia would be a problem. If arrhythmia does not occur during ECG in a hospital, it is difficult for the doctor to know about this health problem for a long time. Today, event monitors have emerged and can be worn during normal activities until the symptoms are apparent and recorded by the instrument. Normally, the wearing time will last up to two months. Many event monitors report recorded cardiac electrical activity directly to the doctor. In this way, doctors can extend their observations beyond the clinical scope, and patients with stable health conditions do not need much follow-up.
As the electronic circuits used in these types of devices become smaller and consume less and less, new applications and applications will emerge in the future. These applications will involve all areas of health in the patient's life, providing a more preventive, cost-effective treatment. At the same time, cheap, convenient surveillance systems will be available to the public through retail stores, which will enable everyone to play an active role in health and wellness.
