Title:
RADIO SENSING DEVICE
Document Type and Number:
Japanese Patent JP2022048188
Kind Code:
A
Abstract:
To provide a radio sensing device that can be operated endlessly without replacing a battery.SOLUTION: A charging type battery is added to a radio sensing device for charging the battery by radio. When electric waves received with an antenna circuit are converted to electrical energy, the battery stores the electrical energy. A sensor circuit is driven by using the electrical energy stored in the battery to acquire information. A signal including the acquired information is converted to electric waves in the antenna circuit, so that the information can be read by radio.SELECTED DRAWING: Figure 1
