Keeping up-to-date on physical conditions and obtaining health information are fundamental measures for disease prevention. Proactive prevention and early diagnosis are crucial for systematic disease prevention. Biomedical sensors, as a new type of medical device, can provide this information in a timely manner. For patients with serious and chronic illnesses, as well as those working in hazardous occupations, the use of wearable or wireless implantable sensors for real-time monitoring of their vital health characteristics is particularly important.

The development requirements of the medical field are closely linked to the advancement of biosensors. The use of biosensors for real-time monitoring and screening of patients is becoming increasingly important. Telemedicine, disposable sensors, and remote consultation services will gradually expand as the demand for home care grows. These factors dictate that the future development of biomedical sensors will feature low cost, low power consumption, intelligence, miniaturization, multi-functions, remote power supply, non-destructive testing, and wireless transmission.In the current medical field, there are many methods for detecting relevant medical parameters. Most biochemical medical sensors use invasive methods to detect patients, which is painful and not conducive to diagnosis. Therefore, the use of non-invasive and non-destructive medical sensors for detection has become the most ideal detection method. The development of non-destructive medical sensors is also a key focus of biomedical sensor development.

Nanotechnology is the design, manipulation, and use of materials at the atomic and molecular levels, enabling them to develop new functional, biological, chemical, and mechanical properties. The combination of biomedical sensors and nanotechnology holds great potential for development. In particular, the development of biochips, nanobiosensors, and miniature intelligent medical devices will play a positive and effective role in disease diagnosis, treatment, and healthcare.

Currently, critically ill patients are primarily monitored using equipment such as ICUs. However, ICU facilities have several disadvantages, including numerous wiring, complex equipment, high cost, and difficulty in moving. Furthermore, these numerous wiring can have a psychological impact on patients, creating stress and leading to discrepancies between diagnostic data and the patient's actual condition. Wireless medical sensors, developed to address this issue, have no external wiring connections and instead connect to wireless sensor networks via wireless communication infrastructure. This allows patients to complete testing while moving freely and normally, ensuring more accurate and convenient testing.
