The rapid detection of various biological samples (liquid, gas, secretion, tissue, etc.) of human body to determine one or more key physiological and biochemical indexes is a common means in diagnosis and treatment. The electrochemical sensor can catalyze or control a specific chemical substance in a sample to generate an electrochemical reaction under the drive of electric energy, and the concentration of the chemical substance to be detected can be obtained by measuring electrical parameters (such as voltage, current, impedance and the like) of the reaction process of the electrochemical sensor. The detection device based on the electrochemical sensing principle has been widely used in many medical fields, and is applied to household medical equipment, such as a portable blood glucose tester, because of its simple equipment and low cost.

First, step S01 is executed, and the circuit part 130 wirelessly communicates with the external reader/writer 200 via the coil 120 and obtains power to start the electrochemical sensor 110.
Specifically, the external reader/writer 200 starts the NFC function, and transmits a communication instruction to the outside by transmitting an electromagnetic signal.
The external reader/writer 200 is close to the detection device 100, and after receiving the electromagnetic signal from the external reader/writer 200, the coil 120 processes the electromagnetic signal through the communication and energy acquisition module 131 to read the communication instruction sent by the external reader/writer 200, and obtains electric energy from the electromagnetic signal to supply power to the control module 133.
After the control module 133 is powered on, the communication instruction read by the communication and energy collection module 131 is processed.
The communication instruction comprises a query instruction and a detection instruction. When the communication command is a query command, the detection apparatus 100 enters a query mode.

After the initialization of the measurement module 132 is completed, a working voltage is provided to the electrochemical sensor 110, the electrochemical sensor 110 drives the detection sample to generate an electrochemical reaction, and outputs a corresponding electrical parameter to the measurement module 132.
Next, step S03 is executed, in which the circuit component 130 acquires the electrical parameter from the electrochemical sensor 110, generates a detection result according to the electrical parameter, and sends the detection result to the external reader/writer 200 through the coil 120.
Specifically, the measurement module 132 collects, preprocesses and amplifies the electrical parameter output by the electrochemical sensor 110, so as to be read by the control module 133; the control module 133 processes, filters and calculates the electrical parameters to generate communication data; the communication data is sent to the coil 120 through the communication and energy collection module 131; the communication data is transmitted to the external reader/writer 200 through wireless communication between the coil 120 and the external reader/writer 200.

If the algorithm determines that the detection amount fails due to user operation or other reasons and the detection result is unavailable, the information of the detection failure and the specific reasons are also sent to the external reader-writer 200 through the communication and energy collection module 131.
The external reader/writer 200 receives the detection result sent by the detection device 100 and reports the detection result to the user in the form of text, image, voice, video animation, etc. In the other embodiments of the present invention, the external reader/writer 200 receives the detection result sent by the detection device 100, and then enters the third sub-program, and performs some complex data filtering, unit conversion, and peer-to-peer processing with the standard value on the detection result, and then reports to the user, so as to facilitate the user to use and read the data.
