The acquisition part 3 is used for monitoring or recording physiological signals or environmental states of a living body and acquiring corresponding data. The acquisition part 3 and the circuit layer 1 are also in electrical connection, and the circuit layer 1 transmits the data acquired by the acquisition part 3 to external equipment, such as a monitor, a mobile terminal, an intelligent router, an intelligent television and the like. The absorption layer 2 is used for absorbing with the skin of a living body such as a human body, etc. during the use of the sensor, so that the sensor can be fixedly combined on the living body such as the human body, etc. for continuous monitoring.
