Recently, the team led by Chinese Academy of Sciences Beijing Institute of Nano Energy and Systems Li Zhou and the Chinese Academy of Sciences Wang Zhonglin foreign team led by Beijing Anzhen Hospital and Chaoyang Hospital, experts developed a Bluetooth signal amplification can be transmitted, for cardiovascular disease warning and Diagnostic self-driven ultra-sensitive pulse sensor.
Pulse sensing technology is one of the most widely used sensing technologies, but the pulse sensing devices still face severe challenges in terms of sensitivity, signal-to-noise ratio, power consumption and cost.
The new device developed in the test successfully converted pulse vibration directly into an electrical signal of up to 1.52V with a signal-to-noise ratio of 10 times that of a photoelectric pulse sensor and a price of 1/5 of the latter. Integration of the pulse sensor with the Bluetooth module enables wireless transmission of pulse signals and visualization and analysis on a smartphone / computer. Using the pulse sensing system, researchers conducted a comparative study of a group of healthy adults and a group of patients, successfully prompted the diagnosis of arrhythmia (atrial fibrillation) and the differential diagnosis of coronary heart disease and atrial septal defect.
This work validates for the first time the feasibility of self-driven sensing technology based on friction nano-generator in the diagnosis of cardiovascular diseases and provides a new idea for the development of mobile intelligent health care.
Powder metallurgy is an industrial technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metal powder) as a raw material, after forming and sintering, to produce metal materials, composite materials and various types of products. Powder metallurgy technology has been widely used in the fields of transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industry, and has become one of the most dynamic branches of new materials science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability, which is very suitable for mass production. In addition, some materials and complex parts that cannot be prepared by traditional casting methods and mechanical processing methods can also be manufactured by powder metallurgy technology, which has attracted the attention of the industry.
