Abstract: This application discloses a thermoelectric power generation structure and a temperature measuring sensor. The thermoelectric power generation structure includes: a semiconductor power generation element, a first thermal-conductive element arranged in a first environment and connected to an inner side face of the semiconductor power generation element, and a second thermal-conductive element connected to an outer side face of the semiconductor power generation element. When there is a temperature difference between the first environment and the second environment, the semiconductor power generation element generates electric power. This application solves the technical problem that the thermoelectric power generation structure cannot match a sensor probe and fails to create a thermoelectric power generation environment, and accordingly cannot effectively generate electric power to the sensor probe in an enclosed high-temperature food heating scene.

Abstract: This application discloses a wireless low-frequency communication method and a wireless low-frequency communication system. The wireless low-frequency communication method includes: a first low-frequency communication terminal modulates a first carrier signal loaded with first data into a first low-frequency signal and sends the first low-frequency signal to a second low-frequency communication terminal. The first data refers to instruction data issued by a user. When receiving the first low-frequency signal, the second low-frequency communication terminal demodulates the first low-frequency signal into the first carrier signal and analyzes the first carrier signal to obtain the first data. Communication is carried out through wireless low-frequency signals penetrating metal shields. Communication signals can be strengthened while communication distances can be increased with the metal shields.
