Folded paper-structured body surface sweat electrochemical sensor and monitoring method

Abstract

The invention discloses a folded paper-structured body surface sweat electrochemical sensor and a monitoring method, and relates to the electrochemical field. A paper substrate in the sensor is foldedto form 5 layers of paper structures; each layer of the paper structure is composed of a drainage layer and a hydrophilic layer; in the folding state, a first hydrophilic layer on a sweat collectinglayer, a second hydrophilic layer on a sweat diversion layer, a third hydrophilic layer on a sweat analyzing layer, a fourth hydrophilic layer on an electrode bearing layer, and a fifth hydrophilic layer on a sweat evaporating layer are contacted layer by layer to form a vertical channel, in which the sweat is diffused from the bottom of the sweat collecting layer to the top of the sweat evaporating layer; an electrochemical electrode system is set on one side of the electrode bearing layer folded towards the sweat analyzing layer; and an electrode detection end is contacted with the third hydrophilic layer on the sweat analyzing layer. The sensor and the monitoring method provided by the invention can separately collect, detect and evaporate the sweat, and reduce the mutual interference;the sweat is capable of flowing; the timeliness and the accuracy of the detection are improved; and at the same time, the discomfort of the user is reduced.

Description

technical field [0001] The invention belongs to the field of electrochemistry, and in particular relates to a body surface sweat electrochemical sensor with origami structure. Background technique [0002] Human sweat contains a variety of metabolites, such as lactic acid, glucose, sodium ions, potassium ions, etc. These metabolites can well reflect the physiological state of the human body. For example, the content of lactic acid in sweat can well reflect the status of oxygen metabolism. When the content of lactic acid in sweat increases, it means that the oxygen content of cells is low; the content of glucose in sweat can reflect the concentration of blood sugar in the human body. Very important. [0003] Wearable devices can continuously monitor the physical state of the human body in real time, and have received extensive attention in the field of health monitoring. Physical sensors for monitoring physiological electrical signals, such as heartbeat, blood samples, and...
