Due to the gradual improvement of living standards in recent years and the continuous improvement of China’s health care awareness, the aesthetic medicine model has gradually changed from the treatment mode of disease treatment to the prevention mode of early detection and early treatment. Meanwhile, wireless sensor networks (WSNs) are gradually infiltrating into the medical field due to their low power consumption, small size, wireless transmission, and portability which complies with the needs of the development of medical models. Therefore, this paper studies and implements a beauty medical health monitoring system based on WSN and ZigBee short-range wireless transmission protocol; moreover, wireless power transfer (WPT) technology is used for charging sensors. Experimental results demonstrate the feasibility that the maximum power levels converted in sensors by the WPT for different ISM bands can meet the average power consumption expected in the range of 200–500 μW. And the designed system can provide an important practical reference for promoting the informationization of telemedicine and the development of beauty medical systems in China.

Research on the field of crane health monitoring has been conducted for the strain monitoring demand on the using of key components of crane and major safety monitoring requirements of crane in China. Strain monitoring nodes based on wireless transmission network have been designed, and crane structure health monitoring system has also been developed on the basis of this technology. The system has been taken contrast experiments with strain gauge acquisition equipment on-site, and the results of experiments show that this system could not only measure accurate strain, but also realize the real-time monitoring and reflect the stress state of crane on operation in time.
