The disposable self-sensing signal test piece 1 can be used in combination with a receiving element 2 that is not mechanically connected to the disposable self-sensing signal test piece 1, the mechanical connection refers to physical direct contact between the two components, and the receiving element 2 can be, but not limited to, a mobile phone, a tablet computer, a computer, or other equipment that can form wireless connection with the disposable self-sensing signal test piece 1 and can display, process and/or relay the detected parameter signal.
The disposable self-sensing signal test strip 1 comprises a test strip body and a power activation means 3, wherein the test strip body comprises an electrochemical processing unit 30, a wireless transmission unit 40, a power supply unit 50, a substrate 60 and a protective layer 70. The substrate 50 has a detection region 10 for contacting the sample to be tested and a circuit region 20 not for contacting the sample to be tested, i.e. the detection region and the circuit region exist in the test strip body. The detection area 10 is provided with a detection circuit 11, and the detection circuit 11 is electrically connected with the electrochemical processing unit 30; depending on the target analyte or the value to be detected, the detection circuit 11 may include, but is not limited to, a working electrode, a reference electrode, an auxiliary electrode, and/or a detection electrode; depending on the target analyte or the value to be detected, at least a portion of the detection circuit 11 may also include, but is not limited to, a chemical reagent, an enzyme, a catalyst, and/or an enzyme attached to the conductive body to facilitate detection of the target analyte or the value to be detected.
The electrochemical processing unit 30, the wireless transmission unit 40 and the power supply unit 50 are disposed in the circuit region 20, and the protection layer 70 completely covers the circuit region 20, the electrochemical processing unit 30, the wireless transmission unit 40 and the power supply unit 50, wherein the protection layer 70 is, for example, a power supply rim and has air/water tightness.
