Device for detecting physiological signals of human body

Abstract

The invention discloses a device for detecting physiological signals of the human body. The device comprises a plurality of piezoelectric ceramic pieces, a signal acquisition processor and a power supply, wherein the plurality of piezoelectric ceramic pieces are connected in series and / or in parallel to each other through leads and then are connected with the signal acquisition processor, and the signal acquisition processor is connected with the power supply; the plurality of piezoelectric ceramic pieces are laid on a liner in a dispersed way. The plurality of piezoelectric ceramic pieces are connected in series and / or in parallel to each other through leads and then are connected with the signal acquisition processor, accordingly, the plurality of piezoelectric ceramic pieces are laid below a mattress in the use process and are small in thickness, the thickness of the ceramic pieces determines the thickness of the device for detecting the physiological signals of the human body, and the device is comfortable to use; the plurality of piezoelectric ceramic pieces are foldably collected together to facilitate storage and carrying; the piezoelectric ceramic pieces are a passive sensing device, can save energy, can directly generate electric signals under pressure, are sensitive, and have better sensing effects.

Description

technical field [0001] The invention relates to the field of collecting human physiological signals, in particular to a device for detecting human physiological signals. Background technique [0002] There are many devices for detecting human physiological signals. For example, if a pressure sensor is installed in a mattress, it needs to convert the pressure into an electrical signal and transmit it to the signal acquisition processor; for example, if a piezoelectric film sensor is installed in a mattress, it needs to convert the pressure into a tension Stretch force, sensitivity is not high; for example, if a hollow capsule is set in the mattress, and the tension of the hollow capsule is collected, the production process is complicated; for example, the piezoelectric ceramic sensor is wrapped in a hard object, and the hard object is made into a Objects with a certain thickness, when in use, are placed at the center of the mattress, so that the center of the mattress protrud...
