The application of medical equipment or technology has driven the overall market demand for medical sensors , but as the degree of networking of these sensors increases, the application of sensors may encounter a network crisis. With the continuous advancement of technology, sensors are increasingly used in the medical field, and these sensors can be used to monitor the most timely conditions. With the development of technology, wireless medical sensor nodes are gradually developing in the direction of multi-parameter, intelligent, miniaturization and low power consumption, and wireless sensor networks will gradually be applied to the medical field. The development and establishment of intelligent ward and community monitoring systems is the trend of medical development at home and abroad. The medical sensor node and the monitoring base station form a personal/home or ward wireless sensor network, and multiple such networks can form a community or an entire hospital monitoring network, or even a larger range of telemedicine monitoring systems. First, the medical sensor node collects physiological parameters of the human body, and after the simple processing of the collected parameters, the data is transmitted to the base station directly or indirectly hop by hop by means of wireless communication. The monitoring base station further processes the data and forwards it to the monitoring center. The monitoring center performs analysis and processing, and timely feedbacks the patient. The monitoring center can also use multiple methods (Internet, mobile communication network, etc.) for remote data transmission and share information with other monitoring centers. Although the application of medical sensors is very attractive, as the network of sensor devices increases, the network security of these sensor devices used in the human body is also facing an increasingly severe situation. Among them, the implantable cardiac defibrillator is mainly used to monitor whether the heart beat is regular and normal, and if necessary, the heartbeat is normal by discharge. The pacemaker uses electrical pulses to maintain the heart's beating. Security vulnerabilities in implantable medical devices are not the first to be discovered, but the study reveals new safety risks for common analog sensors that rely primarily on special activities from the human or surrounding environment as input. Denis FooKune, a postdoctoral researcher at the University of Massachusetts, said they found that these analog devices trust the messages they receive from sensors. Although these medical systems and even consumer electronics have security mechanisms, the information received by analog sensors bypasses their security layer. The device directly converts the input from the sensor into digital information, allowing them to make quick decisions. The researchers also discovered ways to tamper with consumer electronics. They use specific radio signals to pair the microphones on the phone with the Bluetooth headset, FooKune said that such technology may be used for fraudulent transfers, and in another experiment, they canceled the sound of one of the calls in a network call. The signal is replaced by a song. However, Yongdae Kim, a professor of electrical engineering at the Korea Institute of Science and Technology, pointed out that these types of interference can be prevented by the shielding and filtering techniques used today for military-grade equipment. He further stated that more and more safety-critical systems such as smart grids and automated transportation are increasingly relying on sensing technology, but malicious input signals and modified antennas and power supplies can cause serious safety problems. Our PP Resin has a very stable physical and chemical properties according to our professional tests. In addition to the great resistance of shocking strength and other mechanics performance, it also has a good processing performance. Our products have a high heat resistance property which allows us to apply the products in a high temperature environment. Also, the resin pellet has a lazy chemical property, it will not have a react with our daily medical medicine easily. And this also gives us a safety guarantee.
