Since its reform and opening in 1978, China’s economy has grown rapidly and human life and physical well-being have improved significantly. The public health care system is an imperative guarantee of people’s life and physical health. It is necessary to establish a reasonable planning, a reasonable division of labor, and an efficient medical service system to improve the overall efficiency of health care services and ensure the physical health of the people. The balance of public health care services plays a very important role. It plays a very important role in safeguarding people’s basic right to health, regulating social fairness and justice, promoting the sustainable development of medical and health services, and building a harmonious society. Based on 5G sensor technology, this paper combines relevant research on sensor technology at home and abroad and comprehensively uses related theories such as sensing principles and health care services to discuss the internal operation mechanism of China’s public health care service system. It conducts experiments to compare health care services with 5G sensor technology with existing health care service systems. It compares its bed occupancy rates, hospital admissions and discharges, outpatient and emergency department volumes, and average inpatient costs. It studies the impact of 5G sensor technology on public health care services. The experimental results show that after adopting 5G sensor technology, the average bed utilization rate in the H hospital is 88.71%. The total number of hospitalizations was 9.845 million, and the total number of discharges was 8.668 million. The total number of outpatient visits was 44.259 million, and the total emergency department was 7.694 million. The per capita cost of inpatients in H hospital is 15,840 yuan, and the per capita cost of inpatients in W center is 9,661.75 yuan.

The highest beam efficiency in a wireless power transfer (WPT) system that uses focusing components was 51%, using a $$\approx {3}\,{\textrm{m}}$$ ≈ 3 m diameter reflector for a transfer distance of $${7.62}\,{\textrm{m}}$$ 7.62 m . We have beaten that record, and present here a system that surpasses it by 25%. Using the quasioptical framework for reducing spillover losses in WPT, we present a double-reflector system that achieved a higher beam efficiency than the state-of-the-art. The transmitting and receiving antennas were 3D-printed conical smooth-walled horn antennas, specially designed for this purpose. The theoretical analysis enabled the design of a $${5}\,{\textrm{m}}$$ 5 m system, whose energy focus location has been experimentally verified. Then, the complete system was experimented upon, enabling a high beam transfer efficiency of 63.75%. Additionally, the advantage of using quasioptics in radiative wireless power transfer applications is discussed, as well as the sensitivity of its systems. Finally, a comparison with the state-of-the-art is done by the proposal of new figures-of-merit, relating the systems’ physical dimensions and beam efficiency. This research is a paradigm shift by presenting a promising path for future WPT research through quasioptics, whose high efficiencies may enable commercial applications of this technology for solving power supply issues in our society.

“…Resonant inductive wireless power transfer (WPT) is an attractive and efficient way for recharging electronic devices [1][2][3][4]. The simplest implementation consists of just two magnetically coupled resonators in a single-input-single-output (SISO) configuration where power is wirelessly transferred from a single transmitter to a single receiver.…”

Multiple Input Multiple Output Resonant Inductive WPT Link: Optimal Terminations for Efficiency Maximization

et al. 2021

View full text Add to dashboard Cite

In this paper a general-purpose procedure for optimizing a resonant inductive wireless power transfer link adopting a multiple-input-multiple-output (MIMO) configuration is presented. The wireless link is described in a general–purpose way as a multi-port electrical network that can be the result of either analytical calculations, full–wave simulations, or measurements. An eigenvalue problem is then derived to determine the link optimal impedance terminations for efficiency maximization. A step-by-step procedure is proposed to solve the eigenvalue problem using a computer algebra system, it provides the configuration of the link, optimal sources, and loads for maximizing the efficiency. The main advantage of the proposed approach is that it is general: it is valid for any strictly–passive multi–port network and is therefore applicable to any wireless power transfer (WPT) link. To validate the presented theory, an example of application is illustrated for a link using three transmitters and two receivers whose impedance matrix was derived from full-wave simulations.
