Problems solved by technology
However, since charging takes a certain amount of time, the patient needs to move while wearing the cable, which may cause the cable to become entangled or tripped.
In this way, it is a fact that the range of motion of a patient undergoing home medical care and hospitalization is limited by a cable
On the other hand, the medical equipment used in the operating room also has the problem of entanglement or tripping due to the use of more power cables
In particular, if medical staff or patients trip over the cables, the drip tube or artificial breathing tube will fall off, which may lead to major medical accidents.

Abstract
The present invention provides a power supply system and the like suitable for wireless power supply to medical equipment. The medical microwave power supply system (1000) includes: a power supply device (200), which has a power supply circuit (220); and a power receiving circuit (100), which receives wirelessly supplied power from the power supply circuit (220), and Schottky barrier diode (113) for rectification. The Schottky barrier diode (113) uses nickel nitride to form its electrodes. With the above configuration, the reverse leakage current of the Schottky barrier diode can be reduced even at high temperature, and heat generation can be suppressed. Especially in medical equipment where the influence of heat generation on the human body and equipment must be considered, it is extremely important to suppress the amount of heat generation, and it is possible to safely and stably wirelessly supply power to medical equipment.
Description
technical field [0001] The invention relates to a medical microwave power supply system, a medical power receiving circuit, a Schottky barrier diode and a medical microwave power supply method. Background technique [0002] Various methods have been proposed as a wireless power feeding method for wirelessly feeding power. Among them, although a microwave power supply system using microwaves has been proposed, it has not been put to practical use (for example, Patent Documents 1 to 5 and Non-Patent Documents 1 to 2). The medical field is mentioned as a field where such a microwave power supply is expected. In particular, medical equipment used in operating rooms and medical equipment worn by patients, such as portable electrocardiographs, pulse oximeters, pacemakers, etc., need to be supplied with driving power and are driven by secondary batteries. However, the battery capacity of the secondary battery is limited, and generally the larger the capacity, the larger the size....
