The above-mentioned related art can be seen in US Patent Publication No. US2009/0078588A1 and US2009/0145754A1, which are not described herein again.

It should be noted that the implementation of the sensing unit 226 and the sample solution as the object to be tested are merely illustrative and not limiting. For example, in another embodiment, the present sensing unit 226 can be designed to sense biological characteristics of other objects to be tested, such as a certain physiological parameter of the human body (such as blood pressure or body temperature), that is, the sensing unit. It can be a blood pressure sensing unit or a temperature sensing unit. However, the above techniques are readily known to those of ordinary skill in the art and will not be described again.

The mode of operation of the biological characteristic sensing system 200 of the present embodiment will be described below. First, the user places a sample solution such as a blood sample on the chemical reaction zone 226c of the biosensor test piece 220, and places the biosensor test piece 220 within the range of wireless communication of the metering device 210, for example, The biosensor test strip 220 is adjacent to the metering device 210. Then, the user sends a connection signal to the bio-sensitivity test strip 220 through the metering device 210, so that the processing unit 212 of the metering device 210 first identifies the bio-sensitivity test strip 220, and if the identification is correct, the metering device 210 and the bio-featured sense The test strip 220 is successfully radio coupled.

Then, based on the power provided by the power supply unit 214, the processing unit 212 of the metering device 210 transmits a power signal to the transceiver unit 224 of the biometric test strip 220 by the transceiver unit 216. Then, in response to the power signal, the processing unit 222 of the biosensor test strip 220 enables the sensing unit 226 to sense the biochemical substance in the test sample solution. In this embodiment, after the power signal is received by the antenna 224a of the transceiver unit 224 and rectified and stabilized by the rectifier regulator 224c, the rectifier regulator 224c transmits a working power signal to the processing unit 222, so that the processing unit 222 The enabling sensing unit 226 senses the biological characteristics of the analyte. In detail, where the working power signal is received The processing unit 222 provides a voltage difference (which can be regarded as a voltage driving signal) between the working electrode 226a and the reference electrode 226b to generate and measure the current flowing through the working electrode 226a, the chemical reaction region 226c and the reference electrode 226b. The magnitude of this current (or current value) can substantially reflect the quantitative amount (eg, blood glucose concentration value) of a certain biochemical substance in a sample solution such as a blood sample. In other words, when a sample solution such as a blood sample is used as a test object, the quantitative amount of a certain biochemical substance (for example, a blood glucose concentration value) can be used to indicate a certain biological property of the blood sample ( For example, blood sugar levels).

Then, based on the sensing result (ie, the measured current value) of the sensing unit 226, the processing unit 222 transmits a sensing data signal to the transceiver unit 216 of the metering device 210 by the transceiver unit 224. The sensing data signal has relevant information of the sensing result of the sensing unit 226. In this embodiment, the processing unit 222 of the biometric test strip 220 sequentially transmits the sensing data signal to the transceiver unit 216 of the metering device 210 via the wireless connector 224b and the antenna 224a.

Then, based on the sensing data signal, the processing unit 212 of the metering device 210 stores the information of the sensing data signal in the storage unit 218, and the information of the sensing data signal corresponds to a certain biochemistry. The size of the substance (for example, the blood glucose concentration value) is displayed on the display unit 219. In another embodiment, the processing unit 212 of the metering device 210 can correct the information of the sensing data signal according to the external temperature or the correction mode, and store the corrected information in the storage unit 218, and the corrected information. The quantitative correction value of a certain biochemical substance corresponding to the information is displayed on the display unit 219.

Finally, the user cuts off the radio coupling state between the metering device 210 and the biometric test strip 220 by the metering device 210.

Since the metering device of the biometric sensing system of the present embodiment and the biometric test strip are electrically coupled in a wireless communication manner during operation, the signal is transmitted, so compared with the prior art, the present creative embodiment The metering device does not require physical contact with the biosensor test piece, so that the metering device of the present embodiment does not suffer from the damage of the connector of the conventional metering device after repeated use. Therefore, compared with the prior art, the electrical coupling relationship between the metering device of the biological characteristic sensing system of the presently-created embodiment and the biosensory test piece can maintain a better state under frequent use.
