How will sensors change the world in the next 50 years?
Since the birth of the sensor, since it can help humans turn the once unknowable and difficult to judge information into easily accessible and more accurate data, the sensor has become the most important infrastructure in the digital society. In 2011, Mark Anderson, founder and venture capitalist of Netscape, put forward a very original view that has become a reality: "Software is eating the world." To this day, if the "software" in the sentence is replaced with "sensor", this view also applies.
From smart phones to smart voice devices, from energy platforms to industrial equipment, sensors naturally "incarnate" as humans connecting machines, humans themselves, and the extended organs of the natural environment.
With the development of sensors and related software and hardware technologies such as data storage, energy storage, new materials, and network infrastructure equipment, as well as the continuous decline in costs, the application scenarios of sensors will become more and more abundant.
It is predicted that by 2020, there will be 300 billion sensors in our daily lives around the world, the market size will reach 10.5 billion US dollars, and the market size of printable flexible sensors will reach 7.3 billion US dollars.
So, what are the uses of sensors today? In the future, even in the next 50 years, what kind of evolution will sensors experience, and how will they change the world?
sensors everywhere today
From consumer electronics to agriculture, from transportation to medical care, from energy to aerospace, from industry to urban management, sensors have been deeply integrated into human production and life.
1. Consumer Electronics
In the field of consumer electronics, with the continuous increase of human demand for functions, more and more sensors are integrated in various products. For example, smart phones are equipped with more than ten kinds of sensors, such as light sensors, distance sensors, gravity sensors, gyroscopes, GPS, and fingerprint sensors.
2. Agriculture
In the agricultural field, through sensors installed on animals or in farmhouses, we can monitor animal health and various risks in real time to minimize animal diseases and mortality, and increase productivity and fertility. Through field sensors, we can accurately understand weather and soil data to determine the best time for planting, irrigation, fertilization and harvesting.
3. Architecture
In smart buildings, sensors can monitor the air quality, light intensity, smoke density, temperature changes and other data inside the building in real time, so that we can better manage indoor air quality, reduce energy consumption, and improve the living and working environment.
4. Medical care
In terms of health care, sensors can be used to manage medications and lifestyles of patients with chronic diseases such as diabetes and hypertension, and can also help children or caregivers to monitor elderly people with diseases such as Alzheimer's or Alzheimer's in real time the behavior of. When an abnormality is found, you can immediately seek medical help or call emergency services.
Through sensors, doctors can remotely monitor the patient's heart rate, blood pressure, blood sugar, ECG and other health indicators, and can take electronic pills to understand the patient's medication and treatment status, and give timely guidance and suggestions. In general, sensors can reduce hospital costs, improve medical quality, and reduce the frequency of expensive emergency admissions and hospitalization costs.
5. City Management
For urban management departments, sensors can help managers understand the operation of underground lines and equipment such as gas, electricity, tap water and sewage in real time; they can monitor the flow of road vehicles and pedestrians in real time, and adjust transportation strategies in time to reduce traffic congestion; they can tell Where does the car driver have spare parking spaces to avoid unnecessary time wasting and reduce carbon emissions; it can even detect and track the outbreak and spread of diseases.
6. Other fields
Without sensors, there would be no Internet of Things, and no Industry 4.0. In industry, energy, military and other fields, sensors can realize predictive maintenance of equipment. By analyzing and processing data collected by sensors, they can respond to potential problems, thereby minimizing equipment downtime costs.
