    Expanding application areas of embedded sensors
    With the advancement of modern hardware in sensors and software components, embedded sensors have become an active and evolving field of embedded computing, and people can see their expanding applications in many fields.
    The IoT platform can use various sensors to operate and provide various intelligence and data.
    They are used to collect data, push data and share data with the entire network of connected devices.
    All this collected data allows devices to operate autonomously, and the entire ecosystem is becoming "smarter" every day.

     

    Medical equipment is used today to diagnose, monitor or treat diseases, or to provide support for people with physical disabilities.
    Various types of sensors are used in medical applications, including temperature probes, force sensors in kidney dialysis machines, airflow sensors in anesthesia delivery systems, and pressure sensors in infusion pumps and sleep apnea machines .
    The implantable pacemaker is a real-time embedded sensor system that can deliver synchronized rhythmic electrical stimulation to the myocardium to maintain an effective heart rhythm.
    Sensor science and engineering actually involve all aspects of life, including safety, security, surveillance, surveillance and general awareness.
    Sensors are essential for industrial applications for process control, monitoring and safety.

     
    Pressure Sensor
      Today's sensors and detectors play an important role in ensuring the safety of nuclear plant workers.
    Nuclear particle sensors have been developed to detect the type of radiation.
    Nowadays, instead of tubes and chambers used for nuclear particle detection, a variety of solid-state sensors can be used.
    Solid-state sensors use materials such as silicon, germanium and cadmium zinc telluride to directly convert incident radiation into electric current.
    These sensors have a high energy resolution, which makes them suitable for detecting accurate radiant energy.
    Silicon PIN photodiodes can be used to detect alpha, beta, gamma and X-ray radiation.

     

      Alpha rays, beta and gamma rays, and neutrons are common forms of ionizing radiation.
    Workers in nuclear power plants receive low-dose radiation.
    The Atomic Energy Management Board (AERB) pointed out that exposure to high levels of ionizing radiation can cause cancer, so it sets limits on radiation doses for workers.
    Nuclear Power Corporation of India (NPCIL) has established strict procedures to keep radiation doses to workers within limits.
    Therefore, it is necessary to regularly record and monitor the radiation dose received by workers.

     

      In the automotive field, safety, rapid identification, timely action, and reliable notifications and warning messages are essential for autonomous vehicles.
    These are monitored by embedded MEMS sensors used in autonomous vehicles.
    Embedded sensor systems include cameras, radars, light-based radar (LiDAR) systems, ultrasonic sensors, wheel speed sensors, and positioning systems (GPS).

     

      Cameras and radar systems really play a prerequisite for all levels of automation.
    Cameras use image sensors to provide information such as speed, distance, and contours of obstacles and moving objects.
    Self-driving cars use rear, front and 360-degree cameras.
    The camera helps the driver to better represent the environment around the vehicle.
    Usually, four to six cameras are required to obtain realistic 3D images.
    The front camera system is used to automatically detect objects within a range of 100-250 meters.
    The algorithm in the camera can identify pedestrians, motor vehicles, side strips, roadsides, etc.
    These can also detect traffic signs and signals.
    Even if the sunlight hits the camera lens directly, the camera needs to have a good dynamic range to provide a clear image.

    Industry 4.
    0, sensors are promising
      Today, the sensor industry is working hard to enhance its pressure sensor product portfolio to improve its operational capabilities in various industries, thereby driving market growth.
    The upgrade of sensors in the market is very fast.
    The purpose of real-time monitoring of machine parameters and equipment is to perform predictive maintenance.
    In addition, due to the improvement of workshop automation, the application field of sensors is also generally increasing.
    IO-Link technology is a digital technology that has been recognized by almost all industries.
    In this industry, IO-Link technology hopes to overcome the traditional challenges of analog systems, such as EMC problems/signal loss, etc.
    , which are very common in analog signals.
    Compared with analog systems, this technology will reduce overall costs.
    It will actively bring big information from sensors into the IoT interface, directly as well as PLC.

     

      Technical experts hope that the sensor can perfectly match the new communication protocol, and can work in high temperature, high pressure and various environments (such as underwater, space, etc.
    ) at a moderate price.
    When it comes to the sensor’s contribution to predicting and preventing future events, it is governed by event data/history, so it needs to be evaluated to analyze the current state of any environment to draw conclusions about the following: the level of deterioration.

     

      Sensors are the eyes and ears of any automated system.
    Therefore, the accuracy and efficacy of any system are critically dependent on the specifications of the sensor.
    Sensors started based on mechanical principles and have even been established on wireless technology.
    They are becoming more and more technology-oriented, with new features, such as wireless sensing, IO-Link, etc.
    In addition, with the advent of Industry 4.
    0, the role of sensors will become more and more important.
    Smart sensors will be needed at every point, and the required information will increase from GO/NO-GO input to a whole new dimension of detailed data from every point on the stage.

     

      As the demand for sensor technology advancement continues to grow to meet the needs of the Internet of Things under the 5G infrastructure, traditional MEMS sensors are facing a new round of development.
    Starting from MEMS manufacturing technology, this is the basis for the actual production of all sensors.
    When manufacturing these novel sensors, new manufacturing methods have been proposed and demonstrated.
    As far as the application of the Internet of Things is concerned, the three main types of MEMS sensors will be widely used in almost all places as the operating frequency increases.

     

      Today, the development of many sensors is underway.
    In the next few years, to maintain new records of all developments and possibilities, things will become more challenging.
    Epidemics and other viral diseases are related to a variety of physiological changes and can be monitored using wearable sensors.
    Many indicators from heart rhythm, such as heart rate (HR), heart rate variability (HRV), resting heart rate (RHR) and respiratory rate (RR), can be used as potential signs of epidemic infection and have been measured by wearable devices .
    Due to the integration of multiple measurements, the total signal-to-noise ratio (SNR) of these indicators is higher than that of a single original signal, and therefore has a higher predictive value.

     

      Seed technology is currently under development to achieve a long-term vision, including intelligent systems that have self-monitoring, self-correction and repair functions, as well as intelligent systems that can modify or deform themselves, which are different from beings.
    The system's ability to see (photonic technology), feel (physical measurement), smell (electronic nose), hear (ultrasound), think/communication (smart electronics and wireless) and move (sensor with integrated actuator) is constantly improving .
    Rapid development and provide an exciting future for sensors.

     

      Integrating sensors into smart devices and systems has improved the ability to measure, analyze, and aggregate data at the local level.
    Autonomously connected sensors can selectively sample and measure many physical properties.
    Based on the ever-increasing functions of fixed access and wireless networks, the development of smart sensors allows the collection of raw data, which is processed into information and transmitted through network connections, making it an important part of today's sophisticated electronic products.
