Abstract

The invention provides a detection microsensor comprising at least one detecting unit 1 and an NFC module 2, wherein the detecting units 1 comprise an extracting electrode 3, a micro-channel 4 and a three-electrode array 5; the extracting electrode 3 transmit the sweat containing substances to be detected to the three-electrode array 5 through the micro-channel 4 for detection to obtain a responsecurrent corresponding to the substances to be detected; and the NFC module 2 is used to convert the response current into a modulation signal. Based on the detection microsensor, the concentration ofphysiological parameters such as glucose, lactic acid and uric acid in the blood can be detected non-invasively.

Description

technical field

[0001] The invention relates to the field of biomedical devices, in particular to a detection microsensor structure and a detection method thereof. Background technique

[0002] Wearable biochips can be attached to the skin, monitor individual vital indicators through physical sensors, or detect individual specific biochemical indicators through electrochemical sensors, and then monitor individual life and health in real time, while existing wearable devices have achieved non-invasive Or minimally invasive detection, so that the wearer feels no pain and abnormality, ensuring the function of normal life and rest. Commercial wearable devices can currently track the position of the human body in real time and monitor basic vital signs, but further extending the use of the device to monitor specific biochemical molecular indicators of the human body and accurately respond has many bottlenecks, such as: molecules in subcutaneous tissue fluid and Whether the conce...
